Slow down and dive a little. A blog about cave diving in Mexico.

This weekend brought two more days of wonderful diving.  On Saturday, I dropped Allie off at Xpu Ha Beach and got an opportunity to explore the down stream section of Minotauro.

To access the down stream section, you swim to the back of the Cenote to the duck under.  At the T you make a right.  This section of cave is definitely sidemount.  There are lines everywhere.  If you make the first jump to the right, you have to pass a fun restriction.  After a couple of minutes you will reach a T.  If you go right, you go through a sidemount restriction and end up under the steps in the cenote.  If you go left, the line ends and you can jump back onto the main down stream line.

If you skip the first jump, you will pass serveral others.  At 30 minutes or less, depending on how much jumping you do, you will reach a 4 way T.  I decided to continue straight ahead.  The cave pinches down and starts to turn back on it self and really snakes around.  It is low and silty.  After another 10 minutes, I could feel the distance pressure building and I turned around.  I had plenty of gas, I just felt like I had gone far enough.  Plus, down stream is a noticeable siphon and when the cave gets smaller the water velocity climbs, making the return trip slower and labor intensive.

When I reached the 4 way again, I had plenty of gas so I decided to check out the branch to the right as you are exiting.  The first thing you come to is a very entertaining restriction.  I decided to remove one tank and was rewarded by passing it cleanly.  The branch was a lot of fun.  The passage was never straight for more than a  couple of meters and really twisted and turned.  There were plenty of minor challenges along the way.  I reached the end of that line in less then 10 minutes.  There are some jumps back there that need to be checked out. I turned and decided to check out the other branch.

The left branch, as you are exiting, was much of the same.  Just great sidemount sized cave passage, beautiful tannic stained decorations and plenty of opportunities to hone my skills.

Total run time was 122 minutes and  my max depth was 20feet. This is really one of those caves you can loose an entire afternoon in.   After I cleaned up, I jumped in the Toyota and crossed the highway to Xpu Ha beach.  I met Allie and Sophia and we had a nice dinner on the beach.  I did some swimming and headed home.   What a great Saturday!

Sunday delivered another excellent dive.  I headed down to Nohoch Na Chich with Patrick, Katy, Alain, Alian's friend and Sonny. Sonny is diving with Protec for the week and is an excellent diver.

Until today, I thought there were only two ways up to Heaven's Gate.   I discovered is there is a third line up there.   It never ceases to amaze me how much line has been laid in Nohoch.   The third line is just to the right of the main line.   The swim from Nohoch to Heaven's Gate took about 30minutes.  When we reached Heaven's Gate we T into another line, made a right and swam for another 30 minutes.  As we approached our turn time of 60 minutes, I could see a small very strong green light in the distance.  I couldn't tell if it was a dive computer or a cenote.  I was really drawn to it, it seemed so out of place.  We reached it at the 59 minute mark, just shy of our turn time.  It turned out to be a very thin shaft of light from either a solution tube or a very small cenote.  I didn't have time to really investigate it.  The swim back was uneventful but fast.  We covered the same distance in 13 minutes less.  We were really huffing it.  Our total run time was 114 minutes and max depth was about 30feet.

When we got back to PlayaDel Carmen, we decided to go to dinner together.  Hannah,  Sonny, John, Patrick, Katy, Allie and I went to Pummarola restaurant on 1st avenue and 40th street.  We had an excellent Italian meal and shared some of our war stories.  There was plenty of laughter and we really had a wonderful time!  If you are interested in the food in Playa Del Carmen, you should check out http://www.PlayaEats.com.  It is a restaurant and food review website.

And a fitness update, for those of you following my weight.  I was down to 234lbs this morning.  I have been bouncing between 235 and 239 for a while.  It has been frustrating.  However, I am starting to spend more time around 234 instead of 239.

Allie, Sol and I committed to a Jeff Galloway running program for a half marathon.   This past week I ran 3.5 miles twice and 4 miles once.  I think this is good progress!  Just a couple of months ago a mile was a challenge.  We are targeting the half marathon distance for December 2008.  I will keep you posted.

After seven months of living in Playa Del Carmen and asking Nando to go cave diving, he finally complied!  Nando had a clear day in his teaching schedule and he could get away from the new baby.  We knew we wanted to go side mounting in some tight passage.  Nando doesn’t pleasure dive in anything but.  We talked about Grand Cenote Down Stream, down stream at Xunaan Ha and the shallow cave at The Pit.  After some negotiation, we decided to go down stream at Car Wash.

Car Wash Cenote is about 7km out Coba Road from Tulum.  It got its name because the taxi drivers used to wash their cars there.  Luckily, they no longer do.  Today, it is a beautiful site with bathrooms, changing rooms and a very nice land manager.  Entrance is $100 Pesos per diver and they close at 5PM.

Car Wash Cenote has two systems connected to it: Car Wash Down Steam and Car Wash Upstream.  Until recently I thought it was one system because you could swim from one to the other.  Well, I was wrong, it is actually two systems.  For the two segments to be considered part of the same system, you must be able to swim between them without being in open water.

The QRSS FAQ on measuring caves lengths states:

"Authentic underwater cave systems must allow a diver to swim to any point in the system without passing through an open water (direct access to the surface) environment. Avoiding an open water portion by swimming underneath a drip line (a rock overhang) to connect two caves is permitted."

Nando and I had both dove portions of Car Wash Down Stream in the past.  In February, after a dive at Naharon and Car Wash Upstream, my buddy Paul and I did a quick dive in the down stream section.  We hadn’t been there before and hadn’t received any guidance, so we were exploring.  We ended up finding the Chamber of the Ancients section.  That section drops down to 90ft and we did the small circuit in the back. When we returned to the entrance, we discovered earned a deco obligation on our Sunnto computers.  Opps…. Neither of us ever considered we might end up with an obligation.  The lesson is when you do repetitive dives with consistent depth; you really need some awareness and watch your no stop time or plan better.

On this day, Nando and I agreed to make a dive to the Lower White Room first and then if we had enough gas, return the sign, recalculate thirds, and head towards Satin’s Silt Hole.  We reached the end of the line in the Lower White Room in a little under 18 minutes.  A good part of this dive is sidemount only.  The cave goes up into a tight bedding plane full of tanic water.  Then turns left and drops through a restriction and you bust into clear water.  The cave in this section is in excellent condition.  It is highly decorated and stark white.  I guess  its good condition is the result of needing to be in sidemount to reach it.  Unless you go tanks off, you can not reach it in backmount.

On the return we checked out the jump marked by a red arrow just prior to the restriction.  A couple of minutes of hunting and we didn’t find the jump.  I believe it is there, it is on the map, just another opportunity to go searching.

We followed the plan and reached the sign with 1800psi in each tank.  We recalculated and went towards Satin’s Silt Hole.  Looking at the map, I don’t think we entered it.  We swam down the larger passage to the left, tied into the line and found the end, which was another opportunity to jump.

We turned the dive and discovered an unmarked jump.  We had plenty of gas so we elected to check it out.  The line was covered in some super soft floaty silt.  The kind that when you swim by it, it just jumps up at you.  That whole section of the cave is covered in that stuff and it was sidemount cave.  I am sure you can image the result. As the number two man, I got to navigate the cave in limited and zero visibility.  There was at least one restriction that required the removal of a tank.  We turned the dive on thirds as the cave came up to about 10feet.  The exit trip was a little nicer, the silt had settled and I could see where I was going.  It always seems like you have traveled so much further then you really did in the silt out.

Car Wash Down Stream was an excellent sidemount cave dive.  There were tight spaces, restrictions, silt, tanic water, beautiful formations and some inviting no mount leads.  I think it is worth at least one more visit.

Thursday brought the return to more normal diving for me.  I met up with Alain, a swiss tech instructor, helped him through some issues with his Nomad Sidemount rig and drove down to Minotauro for a leisurely cave dive.  Minotauro is nestled in the jungle near the Zero Gravity Dive shop.  The landowners are super nice people and there is always a laugh when we meet with them.

Which brings me to another related topic.  There is a rumored connection between Minotauro and Taj Ma Hal.  I haven't found it if there is.  Maybe it is like the swimming pool at my grammar school.  You know, the one in the basement.   Every once in a while we get the feeling like we should go looking for it.  The entrance to Taj Ma Hal and Minotauro are less then 2000 apart.  I need to make a general survey of each system and see if they trend toward each other and how far apart they might be.  Could be an interesting project if I were bored.  If you have any information on this rumor, let me know?  Might save me some heartache.

Back to the dive!  Alain and I suited up in our side mount rigs and got in the water.  Alian asked me to look at his rig and check it out.  It looked pretty good, there are some danglely issues like his pressure gauge, his crotch ring and his regulator.

If you are wondering what sidemounting looks like, here is a little video.  The first part of the video is Alian in his Nomad Side Mount rig.  The second part of the video is me in my Steve Bogaerts' Razor Sidemount Harness.

The primary complaint with the Nomad is that it is a recreational side mount harness.  It is very general purpose.  It takes a lot of work to get the configuration correct and in the end you may not ever get it.   This complaint is handled completely with the Razor.  The Razor harness is a custom side mount/no mount harness worn under an open water bcd.  I was fitted for my harness when I took my basic side mount class with Steve Bogearts.

Taking the class and getting a custom harness provides two huge benefits.  First, the harness and the bcd fit me perfectly and put me in very good trim and my gear in the right places.   I made two adjustments after I left class.  The first was to add more give in the bcd for more lift.  The second was to add more weight when I got a 9MM suite.

Second, Steve very closely analyzed my configuration and diving for a couple of days providing constant feed back including video.  This feedback accelerated my adjustment to sidemount by 10-15x.  In 5 dives, I was more comfortable then many people I know with 50-100 sidemount dives.  Side mounting just takes a lot of tweaking, and people would rather dive then spend time in open water analyzing and tweaking.  Taking the class enforces a little discipline and starts you off on the right vector.

Ok, back to the dive now.   The entrance to the 'other upstream' is at the back of the cenote under a duck under.  I have dove about 60% of this section in backmount, however, it is tight and hard to not have some impact in that configuration. In sidemount it is much more enjoyable.  This dive includes a very cool carousel formation.  The line passes around the carousel and up into a highly decorated air dome.  After the carousel, it is easy diving until you pass the second T.  The two T's are actually of two circuits of the main line, sort of.  If you go left at each T and then swim to the end of the line, you end up a the second T.  Just prior to getting back to the main line there is a jump to the left.  That is the end of the line from the first T.  it all sounds very confusing and the first time I was up there it was a little confusing.  But now I have a pretty good mental picture of the area.

I should warn you that after the second T it becomes sidemount sized passage and the chance for zero or no visibility, if you are careless, is pretty high.  Please tread lightly and stop when you hit your limit.

I do have one question, there is a mystery arrow at the back of the loop of the main line.  Alian and I searched for the jump for a couple of minutes and couldn't find it.  If you know where to look, email me at: hans@quietdiver.com.

When we reached the cenote again, we had plenty of gas remaining.  This dive has a max depth of 20feet (6 meters).  So, we decided to recalculate and extend the dive again.  Near the duck under there is a line arrow, the jump is 50-60feet and hidden.  That line leads to a very silty side mount section.  This isn't the down stream section.   The line and its branches are pretty short but a lot of fun.  When we arrived the line was in bad shape.  It was loose and the rock it was tied to was broken in lots of places.  Someone trashed the line and left it.  I guess they were a little freaked out.  It goes to zero visibility pretty fast.  In any event, we took some time and restored the line.  It was a good exercise to work on the line in reduced visibility.

The dive was 110 minutes long and we had a great time.  Minotauro is still one of my favorite places to dive!

A traverse from Naharon to Mayan Blue on rebreathers.

This past week has been very busy for Patrick and me.  With the arrival of "Slow Season" here in Playa Del Carmen, we have found more time and more opportunities to get ourselves into some serious dives.  We have made two trips to The Pit and one trip to Sistema Naranjal with our Megalodons.  Luckily, the dives at The Pit were relatively excitement free, other then Patrick reaching the restriction at Jill's Chamber at 105 meters.  However, the dive at Naranjal was anything but boring.

Patrick had finished up a full cave class at Mayan Blue on Sunday.  Unfortunately, the student didn’t complete the A Tunnel / Death Arrow circuit, so we had to retrieve the remaining gear, one spool.  We decided the only reasonable way to do the clean up dive was to traverse from Cenote Cristal (Cenote Naharon) down to the Death Arrow jump, pick up the spool, and swim back.  The swim from Naharon to Mayan Blue typically takes about 2 hours.  We decided to cut the swim a little short by only going to the end of the Death Arrow passage.

When we were planning our bailout gas, I was worried about having enough.  I hadn’t swum this distance and I wasn’t sure of the depths.  Patrick and I agreed to take 2 Aluminum 80’s each.  We ran some calculations and it was enough to get us out if we needed it.  Patrick’s calculations showed that two 80’s would last him 4 hours at this depth.  My SAC is higher, so I didn’t have same cushion.

When it came time to decide on our gas mixes, I asked Patrick what he was taking?  He told me Air.  And then we got into a discussion about bailout.  He very sternly explained to me that the choice of bailout gas didn’t really matter.  He didn’t believe he would ever have to bailout.  However, if he did he would only be punished with deco time.  He explained that he follows a checklist and is meticulous about assembling his unit.  I told him I was going to take 32% regardless of his feelings on the topic and I was going to drop a tank of O2 in the cavern for good measure.  You really never know when something unexpected is going to happen.  Isn't that the definition of unexpected?   We agreed, or I decided in my head, I can’t remember, that if someone bailed out, they would get the 32% and the Air would be the gas of last resort.  At this point, Patrick’s attitude really concerned me and I decided that I was going to have a sit down with him, but I was going to wait until after our dive, as to not mess with his head.

Wednesday arrived and we got on our way.  The dive was going according to plan.  We passed the restrictions heading for Mayan Blue.  At the T, I wanted to "drop" a cookie.  As I got my markers out of my pocket, I dropped my safety spool. I reached for the safety and lost control of my buoyancy and started to fall.  I reached for the inflator, but no luck!  I ended up rolling down the windows saving myself from crashing into the mud, but creating some silting.  I could hear Patrick laughing as he watched this comedy of errors.  I finally got my act together, marked the T and proceeded.  I am sure it looked hysterical, you know how things happen in super slow motion, I know I was laughing about it.

We arrived at the spool at 80 minutes.  He retrieved the spool and we rested briefly.  When we finally got going on the return trip I was in the lead.  We were singing into the DSVs and just enjoying the dive.  After about 10 minutes we settled into a decent rhythm and pace.

At about 20 minutes, I saw a quick flash of the light head of me.  I instinctively turned and started to swim to Patrick.  We were about 50feet apart.  It took me a second to process the situation.  What I saw was one of the breathing hoses from the KISS Classic just floating in the water and I saw Patrick deploying a bailout reg.  My first thought was, ‘Oh shit, what do I do?  My bailout regulators are really secured and are not quickly accessible.’  Before I was close enough to help, he got his regulator out.  I arrived and assessed the situation.  The exhale breathing hose had disconnected from the canister.  At Patrick’s request, I reattached the hose.  We thumbed the dive, changed positions and started swimming.  This is when my heart rate finally picked up and I became aware of the gravity of the situation.  This was a real live catastrophic loop failure way back in a cave.  This is the exact type of unexpected situation we train and prepare for.  I knew we had enough gas, but I still got hit with some adrenalin.  I had to stop and think about my breathing and heart rate for a second.  My heart rate really isn’t under my control sometimes.  The base of the brain just reacts.

As we swam, I stayed near to Patrick in case something else went wrong.  I checked my computer and marked the time.  We had 60 minutes of swimming up stream to exit the cave.  Patrick cleaned up his hose routing and attempted to go back on the loop.  As I watched him attempt this, I just kept thinking, "You can’t recover a KISS from a total flood.  Don’t try."  He found out in short order it was a done deal.  Then I offered him my 32%.  He waved it off, and he started to play with his X1.  Patrick later told me he thought he would be fine on air.  However, a couple of minutes later when we reached the T, he realized he was running out of no stop time and asked me for some 32%.

He asked at the worst time for me.  I was about to pick up my cookie and had too many things going on at once.  I struggled with my tank for a minute and finally told him to start swimming.  It would be easier to make the switch underway instead of hovering.  At this point I made a mistake, I think I was a bit overloaded and my brain was fried.  Instead of doing one thing at a time, I had the tank neck out of the bungee in the left hand.  I reached down to get the cookie with my right.  Now I was swimming with both hands full trying to get my tank completely off.  Ug! What a nightmare!

I finally stopped and stowed the cookie.  Then I passed the tank to Patrick.  He reached down to pull the regulator off the tank and the mouth piece came off!  The irony is that Patrick recently told me it was stupid to put the bungee necklace under the same zip tie as the mouth piece and that the mouth piece would come off at the worst time.  I defended my choice and didn’t change my configuration.  The bungee was wrapped around the tank neck and under the single zip tie.  When he showed me the regulator without the mouth piece, I could hear his voice in my head and I laughed.  I have since changed my configuration for CCR diving.  I removed my 120 degree swivel and the necklace on the bailout regulators.  I want them to be as accessible as possible.  Now, I believe that I will need them at the worst possible time.  He replaced the mouth piece and started to enjoy the joy that is 32% EAN.

Patrick swam off and I struggled with his tank.  This dive taught me my sidemount bungees are too short to be useful in an emergency.  As I struggled with the tank, I swam into the ceiling with my rebreather.  It got a little hung up so I jerked my head down.  I immediately realized my head was way heavy and I was heading for the floor!   A huge rock had broken loose and was on its way to pinning me.  I rolled to the right and the rock fell off my head before I hit the ground.

Again, I laughed.  I couldn’t believe how many things had happened to us on a single dive.  We have been diving for seven months together and all of those dives had been incident free.  A series of walks in the park, including cave dives to 300ffw.  The type of diving that breeds complacency.

I caught up to Patrick and we continued to exit.  We decided to pull our gear.  As I pulled my spool from the jump between Southern Sacbe and Southwestern Sacbe, I created a nasty knot around the main guideline.  I ended up cutting the spool free from the guideline.  It was the last in a row of incidents.  We exited safely with a total run time of 180 minutes.  I estimate the total distance at around 8000 feet.

Patrick and I agreed that we handled all of the situations acceptably.  We did a serious review of the dive and have both made changes to our rigs and attitudes.  As I mentioned, I changed my regulators and I lengthened the sidemount bungee.  Patrick also made some changes to his regulators to ensure they are accessible.  We adjusted our bailout gas attitudes.  And we agreed to take better care to avoid team separation.

Once the stress started to pile on, it made simple tasks like a tank swap more difficult.  A task he and I normally can handle in a minute or less took a couple of minutes.  My overall awareness decreased and we got a good distance apart more then once after the main failure.

I feel it was an excellent dive!  We both returned and no one was hurt.  We tested our abilities as a team, and as individuals in a stressful situation.  We both stayed calm and controlled our breathing.  We reacted instinctively and completed the tasks at hand.  We realized our performance wasn’t perfect but it was acceptable. The whole dive confirmed to me the following idea.  Bailout is for unexpected situations and it does matter.  No matter how bullet proof you might think you are or your procedures, unexpected shit happens and it will happen at the worst time.  And these situations never happen alone, they are always compounded by other events.

Patrick used just over 2000PSI from one Aluminum 80 to exit from 60 minutes into the cave.  I hope you learn a little from this, I know I have learned a lot.

As always, your comments and criticisms are welcome here.  If you want to know more about the incident, leave a comment and one of us will respond.

Okay, they are not really spy photos.  I emailed Rob after I saw his post on his wreck diving blog about his new sidemount rebreather and asked him some questions and if he had any other photos.  I thought that my "valued" readers would love to see more of his unit.   And I have my own selfish motives, I really wanted to learn more about his unit.  I think it is totally RAD!

One of the most popular questions I am asked is, "When are you going to sidemount your rebreather?"  My standard response is, "I am not planning on it anytime soon."  That is followed with, "Why not, Hans?"  I usually answer, "Any place I would want to use my rebreather sidemount would require too much bailout to sidemount effectively.  It might work for survey where I need a lot of bottom time, but I might not be covering a lot distance.  However, I just haven't felt the need."  I think at some point, I might change my mind, just not today.  But I digress, the point here is that you want to see photos of Rob's sidemount Prism rebreather.  Here they are.  Click the images to see a large version.

The unit is still in development in these photos.  Rob had some issues to work out, like the wing and the placement of his light canister.  My understanding is it is progressing nicely.  I asked Rob a couple of questions and here are his answers.

Hans: Have you dove it in the ocean?

Rob: I have indeed taken the sidemount rig into the  ocean.  Did two nice dives on the Arundo last Sunday, 100 minutes and 70  minutes.  Big bag oflobsters, 3.5 dozen scallops, plus an old  bottle.

Hans: How hard is it to kit up on the boat?

Rob: Kitting up is definitely different.  Put on the harness/counterlungs,  cinch everything up.  Sit down, butt clip both sides, hook up manual O2,  display and hud on one side, adv and wing on the other.  plug in the hoses  and connect, a bit of a pain but a one-click manifold is in the works.   Then bungee both sides and I'm set.  Easiest thing is on an engine cover,  barring that to just sit on the ground.

Hans: What modifications did you make to the Prism?

Rob: As you can see from the pics, I'm still wearing the standard counterlungs, just customized - Y-pipes, meg adv, inspiration opv, stock prism drains.

Hans: How is the work of breathing?

Rob:  WOB is the same as a stock unit.  The counter lungs are in the standard position, so I still get all the benefits of over the shoulder counter lungs.

Hans: What kind of weight do you need to trim the unit in the water?

Rob: Weight wise I am using:

• Two 2lbs on top of the harness
• A 3lbs and a 4lbs in the counterlung pockets.  (Prisms have these on the back.  Very convenient.)
• A 5lbs in my right side weight pocket.  Nothing in the left.
• The rig itself has a 3lbs and a 5lbs weight zip tied to the base.

I am possibly a bit heavy in this configuration, but not terribly so for salt water.  I can also use an AL80, in which case I can drop a few pounds.

Hans: Is it hard to turn off the O2?

Rob: It takes nothing to shut off the O2 as the knob is pointed right at my  hip. Can also unclip either side and swing it around in front of me to get through restrictions.

I want to thank Rob for allowing me to post his photos and his response!  And now for the extra special treat.  Here is a photo of a Prism (Right) and a Megalodon (Left) rebreather.  Both are sidemounted in the same fashion.  Click the image for a larger version!

If you want to see a video, I posted a link to Rob in his sidemount rebreather. If you have any questions you want me to ask Rob, let me know by commenting. I will follow-up and get responses as fast as possible. Safe diving and keep on pushing.

The no cave diving streak is officially over.  For the second day in a row I went cave diving!  I wasn't sure where to dive, then I spoke to Nando and Patrick and found out they would be at Taj.  That was all the convincing I needed.  As independent as I would like to believe I am, I do really enjoy the social nature of diving.  Just being at the same Cenote with friends, even if I am not diving with them, is good enough for me.

The plan was to revisit an area of Taj Ma Ha that I hadn't been to in 3-4 months.  This time in sidemount with the idea of looking for sidemount sized passage.  I went down stream on the white line.  The white line runs from Cenote Taj Ma Ha to Cenote Scarada.  The swim time for that traverse is about 30 minutes.  I think the average depth is about 25 feet.

In any event, I swam to the double arrows and jumped to the right.  This jump is just a minute or two short of Cenote Scarada.  A minute or so after the jump, I came to another line arrow.  I tied my reel in and started to poke around looking for the jump.  My first attempt netted me a dead end with zero visibility that required me to navigate turned 90'.  Once I backed out of that mess, I found the jump.  It isn't really in a logical place compared to the arrow.  The jump is beyond the arrow to the left.  There isn't a straight shot from the arrow to the jump, I guess they want to hide the jump a little.  The end of the line has a big red arrow and is hard to miss once you see it.

That line is the sidemount passage I was looking for.  It could be done in backmount, but it would be a big mess.  The cave is complete swiss cheese and there is a lot of really fine white silt and little bits of cave falling down everywhere.  Just my percolation made a real mess of the first part of the passage.  The passage continues to twist and turn and takes you up through a lot more swiss cheese.  It was a lot of fun to dive.  The line continued where I turned.  Not sure if I am going to go back, it seems really unstable back there.  All that swiss cheese rock just gives me the jitters.

I am grateful for the explorers that came before me, however, sometimes the line I find is in the weirdest/worst places.  It is almost like they weren't thinking when they ran it.  This line was particularly bad.   I can't really imagine how they surveyed it.

During most my training with Steve he has stressed one major topic: "line laying and placement".  We spend a lot of time discussing how and where to place the line, what type of tie-offs to use and why.   The idea is that a well placed line will be enjoyable and efficient to survey as well swim.  He told me that the more line I put in and the more I look at line, I will start to notice good line and poorly laid line.  Well, he is right.  I saw some poorly laid line today.  It wasn't dangerous, but it wasn't the cleanest either. End of rant.

After I turned the first part of the dive, I spent some time exploring the rest of the area.  The line I originally jumped onto looped  back the same starting point.  There is another line arrow out there, but I couldn't find the jump.

Sometimes I think, "Nahhh... don't go to Taj.  It is so boring."  Then I go and find out there was another section I hadn't been too.  It is amazing how mch diving can be done at one site and still not see all of it, or experience all of its personalities.

Today, Allie and I finally got out cave diving.  It had been 15 days since my last dive and I felt really wonky!  The original plan was for Patrick, Katie, Allie and I to go to the Cenote off the dirt road past Chemuyil.  Unfortunately, Patrick came down with a bacterial infection, so that left just Allie and I, which turned out to be a real blessing.  I love to dive with my wife and it is nice to go some place new with her.

The site is called Cenote Xunaan Ha, which the Cenote keeper translated to Water Goddess.  To find it, take the first right down the dirt road after Chemuyil. You will pass what looks like a nuclear test site housing development gone wrong on the left and a fork in the road.  The turn in will be on your left.  Drive down the nicely maintained road to the parking area.  Don’t worry there are plenty of signs advertising it on the highway and on the road.

The fee for entrance is 40 Pesos per diver.  The walk from the car to the water is about 150feet.  The Cenote is gorgeous.  One side is all rock and the opposite side is a peat swamp.  The water is clear and the people are super nice.

It took us longer then normal to gear up and once I was in the water, I found that my HID didn’t ignite.  I was bummed, but we had additional lights in the car.  I got another light and we finally got the dive going.  The upstream entrance is pretty obvious.  The main cave line is in the day light zone.  At first I looks like it is going to be a challenge to find the line, but after a minute it appears in the open, plain as day.

The striking thing about this dive is the beauty and the number of options.  There were lines and line arrows everywhere.  It is just right to backmount and Allie and I really enjoyed it.  Max depth was 30 feet; average was around 25.  We turned the dive after 900psi and about 40 minutes.  There was definitely some flow exiting the cave which sped things up a little on exit.

The cave is in good shape.  It is sort of like Minotauro upstream.  I am going to make a couple of more trips back.

When we got back to open water Allie exited and I stayed in to take a look at down stream.  Down stream looks like it is going to be a serious challenge.  It starts out as a cave through the peat swamp.  The bottom and right hand wall are lime stone.  The ceiling and left wall are mud/peat.  There are roots everywhere and it is silty! Kind of scary, I kept wondering when it was going to collapse on me.  The cave looked like it terminates, but there is A LOT of water moving through there.  On my second inspection, I saw that it doubles back on itself and then drops down through a very serious restriction.  It is a siphon so all the percolation and my lack of skills blew it out pretty quick.  I stuck my head in the hole a couple of times and it looks like it is going.  I heard that it is a no-mount restriction but do-able.    We will see.  Maybe I will send the super skinny Patrick ahead of me to inspect it.

Overall it is a lovely new site that is cheap and will require a handful of trips.  It offers plenty of side-mount and backmount opportunities.

My buddy in NJ, has finally received his side-mount Prism.    Check out how slick it looks!  He says he has a little more tweaking to do to make everything thing streamlined.  I can imagine how much time will really need to be invested in getting something so cool exactly right.

He has posted a very cool video of him diving it at Dutch Springs.  Notice all the exposure protection?  If you take a look at his rig, he is wearing his bailout/diluent on one side and the rebreather on the other side.  There is a sphere of 02 at the bottom of the canister.  Overall it is looking very very slick.  Rob, you are a rock star.  Now tell us how it dives!

The interesting thing about side-mounting the rebreather is that it handles the one cylinder or two cylinder for bailout question.  Now you only need one to balance you, the unit is the other.  If you need more bailout, then you just wear them like you would side-mount stages.  And it just looks so much easier on his back.  Of course there are many other benefits, but I am not going to go through them today.

Rob, answer me this, our hungry readers want to know:

• Where are the counter lungs?  Are there 1 or 2?  Looks like they are in the standard position....
• How hard is it to shut down the O2?
• How is work of breadth in the different orientations?  I know I end up in some strange ones in side-mount.
• I wonder what the kitting up procedure is like on the boat?  I have tried to mount my side-mount bottles standing and it can be a real PITA.  I wonder if the same is true about the ccr?
• I wonder how much weight he added to balance that big steel cylinder?

So many questions!  Maybe I will try and score a visit with Rob in September, when I am home.  I would love some detailed photos and answers!

If you have any questions, let me know.

A Broken bed, Whale Sharks, A Pregnant Doctor and Injections, The Real Dive Life!

Where do I start?  Some time in the end of June, when I sat down into bed, I broke the bed frame.  I broke it right where my lower back rests while I am sleeping.  On top of that, add the fact that we were sleeping on a very tired mattress through which I could feel the springs.  I knew that the bed was broken but I kept using it.  My thought was that I could live with it, though it was really starting to bother me.

Then my parents came to town for a whirlwind tour of the Yucatan in my 4Runner.  Their visit and the accompanies stress eliminated all exercising for about two weeks.  Then we drove around the Yucatan at break neck speeds which was followed by some competitive whale shark snorkeling and photography.  The end result was that my back was completely messed up.   I had a lot of pain in the lower back and was unable to bend over.  I stretched and took Aleeve but nothing was working, it was getting worse by the day.

Now for the kicker, I was scheduled to take my CCR Hypoxic Trimix with Steve this week. I had been looking forward to it for a couple of years.  The whole reason I got the Meg was to dive Trimix.  I emailed Steve to let him know my condition and we agreed that mixed gas diving and lower back injuries sound like a terrible combination.   We decided to postpone class.  A TOTAL AND COMPLETE BUMMER!  But, it was the only reasonable and prudent course of action.  It would be awful to take a lower back hit because I was greedy.

It is really a kind of win for both of us.  I was nervous about taking the class this week and Steve wanted to get some exploration done.  I hadn't been putting enough time in on the CCR and I was planning to put a bunch of time on it in the week between my parents and my class.   With my back out of whack, I couldn't put the time on the unit.  Plus, I think the universe was telling me I needed to slow down a little.  I have really been packing in the training and not doing enough practice.  Now I have my reprieve.

And now we are at the needles part of the story.  On Friday, my back was killing me and I couldn't find a chiropractor or a masseuse to look at it.  I had two separate appointments, which resulted in no call no shows from the masseuse.  I blew off ice cream waiting for this guy.  The best Chiropractor in town, which at least 5 people referred me to, had broken his ankle.  And the next chiro doesn't work over the weekend.  So there I was, when Sol saved the day.  He suggested I go to the clinic where he went.  I complied and we stopped in.

Acupuncture needles in my back.We were seen immediately!  We entered the office and there was a very good looking small young girl behind the desk.  She asked if we wanted to do this in English or Spanish?  Which was immediately responded to by Sol, who was wearing a huge shit eating grin, with, "Your a doctor?"  She replied, "Yes, I am a doctor and I am pregnant. I have thirty years."  I asked, "30 years practicing medicine? You look great!"  She smiled and replied, "No, I have been practicing medicine for 6 years."   The consult went well, and she told me I needed to see a specialist and she wanted to get me out of pain.  She prescribed three injections and a three day course of anti-inflammatory.  I was nervous about both, but we talked about the drugs.  The injection is B12 and something else and the anti-inflammatory is just that.  I agreed to the course of treatment under the assumption she was going to give the shot.  Well, that isn’t how it worked out.  She left the room and brought back a nurse, who was a much older and rounder Mayan lady.  I got my shot and went on my way.  She gave a great shot, it just wasn’t the girl behind the desk.  That was the first needle.

On Saturday night, I needed to get my second shot.  I was informed that the pharmacy would give me the injection if I asked.  As it turns out, they wouldn’t.  I could buy my needle and my drugs there, but had to find someone else to inject me.  The pharmacy sent me to the Red Cross.  The Red Cross charged me $5USD or 50Pesos to inject me.  I skipped right to the front of the line.  It was surreal.  I watched the Para-medic prepare the drug.  It was two glass vials that needed to be broken open and mixed in the syringe.  Sol took a picture, which I will withhold.  And the medic laughed his ass off.  Needle number two down.

On Sunday evening it was time for injection number three.  At this point, I was emboldened by our experiences.  So, we hit up the pharmacy for the supplies and we went home.  This time I mixed up the drugs and gave the needle to my wife, Allie, to inject me.  I wanted to save the $5 and risk of airborne staff that can be found at the Red Cross.  Allie had had two glasses of wine prior to being handed the needle, so she was a little nervous and so was I.  She pinned me and pumped my rump full of the drugs.  Everything went according to plan and needle number three was finished.  She did a great job!  I never expected my wife to need to inject me.  I guess that is one of the wonders of the self serve medical system here.

That brings us to Monday!  Today, I went in and had a consult with a physician, a real MD, who specialized in pain management and acupuncture.  We talked about my condition; he examined me and then prescribed a course of Ozone Therapy and acupuncture.  The Ozone is to resolve the herniated disk; the acupuncture is to relieve the muscle tension/spasms.  My homework is to read up on the Ozone treatment.  In the mean time, he stuck 12 needles in me making the count 15.  I had never done acupuncture before, so I was a little skeptical.  However, I have heard good things about it.  It didn’t hurt.  It did put me to sleep.  And it gave me a funny taste in my mouth like my body was detoxing.  I have another visit scheduled for Thursday morning.  I am not exactly sure how I feel about it, though I am willing to give it a shot.  I am going to couple it with a return to my yoga practice and some walking.

I am desperate to get active again.  I hate getting off the beam, acupuncture needles in my leg, and feeling like a slob.  I think I am going to dive this week a little, maybe 2-3 dives, nothing deep.  Though that will really depend on how my back feels.  As of tonight, it seems to be well on its way to recovering!  Hopefully, I will be in tip-top shape shortly.

Plus, Allie, Sol and I have agreed to start a training program to train up to running a half-marathon.  I don’t want them to get too far out in front of me.

Have you tried acupuncture or other holistic or eastern approaches to your pain?  How did it work for you?

Every once in a while I get nostalgic for wreck diving.  I have been trying to organize a trip to the Puerto Morelos wreck for weeks and no one wants to go with me.

I learned to technical dive by diving the wrecks off of New Jersey.   If you haven't dove the North East, by which I mean Long Island and New Jersey, you are really missing out.  Let me describe some of the finer facets of wreck diving in the North East:

• Get up at 3:30AM to drive 1.5-2 hours to the boat followed by a 1.5-2 hour boat ride to the wreck.  50% of the time I find out the trip is called at the dock, 25% of the time divert to tug or the Mohawk in 50ft of water, 25% get to the planned dive site.
• Heavy seas make me sea sick.  I am chronically sea sick.  I have been since I was a mate on my Dad's offshore boat.  One summer, I went to Gloucester, Mass to chase giant tuna.  All I was able to chase for a month was my ass to the gunnel.   Now, I take Dramamine and live with medicine head.  I have  a pretty good solution, one the night before and half of one in the morning.  Controls the sickness and the medicine head.
•  Pull on drysuit with enough under-garments for a two hour dive in 54'F water while sitting in the 90'F summer sun.  Forget to attach the pee valve correctly.  Bath in my own sweat before I get off the boat.
• Roll off the boat into a heaving sea.  Drag myself down the anchor and only realize I am on the wreck when my hand touches it.  Navigate like a blind guy in the muck for 2 hours looking for 2 lobsters I don't eat.  Bag em and give em away.
• On the ride home help Rob Infante shell a couple of dozen scallops.  Sleep for a while.  Start to plan next week's expition.
• Upon arrival, drive 2 hours in the hot traffic home.  Rise my Meg in a 33 gallon garbage pail.  Dry the gear on the lawn and in the yard.  Spend the next two days recovering.
• Calculate the cost for the weekend:  $50 Car Fuel, $125 Boat, $20 Tip, $10Food, Plus Rebreather Costs.
• Schedule it again for the next weekend.

And just for comparison, typical day of cave diving:

• Stop working at 2PM and assemble/pack Meglodon or side-mount gear.
• Dive 25-40 minutes to  dive site.
• Pay $8.00 USD to land manager.
• Pull on wet suit and pee in it.
• Dive for 2-3 hours.
• Drive to Puerto Aventarous and buy a Magna Classic ice cream bar.  They have the best chocolate shell.
• Arrive home and dump scrubber, clean loop, and deposit dive gear in the living room to dry.  It all lives in a laundry basket from Walmart.
• Calculate costs: $10USD Fuel, $8USD Entrance, $1USD Icecream, plus rebreath costs.
• Schedule it again for the next day.

Even with all the insanity of wreck diving, I still love it.  And if I lived in NJ, I would be going almost every weekend year round!  I am one of those crazy guys who goes out in Decemeber, January and February.

My favorite wreck is the USS San Diego.  I can spend hours inside that wreck.  I think my second favorite is the USS Algol and third might be the Northern Pacific.  Unfortunately, I only got on the Northern once, but it looks like it offers tons of opportunities.  I know this is a cave diving blog, however, I think most of us have a soft spot for some challenging wreck diving.  Which brings me to the reason for this post.  My friend Brandon recently got a new camera and published a very nice dive report of a dive on the Stolt Dagali.   A very cool wreck that is just a couple of miles from the USS Algol.  His photos really fired my nostalgia.   And from my recount, I am sure you can see why I misss it!

Your turn:

• Do you wreck dive?
• What is it like for you?
• What is your favorite wreck?
• What boat do you dive from?
• Know any wrecks here in the Yucatan I can go dive?  Must be something out there!
