This is the account of an outing in which some peoples received some very serious injuries.
El pozo del Gavilan, is a sinkhole that I wanted to dive ever since I heard of it. You have to rappel 80m to get to the water.
In 2002 We had everything ready, we where five divers and other five where there also for the ride, we where to use this expedition to accomplish two objectives. Number one was off course the exploration dive into the sinkhole to find the entrance to the cave, go into the cavern area and use this info to plan the cave dive into this system on a latter day. Two, we where also planing to go again on the coming months to descend Golondrinas and Hoya de guaguas so this was a training trip for some of the guys and gals.
So we got there Saturday afternoon sleep well and early morning Sunday started to fix anchors and check equipment (SRT and SCUBA).
10:00 am Wen all was done and came my turn I put on my rack and fix on a 2m piece of webbing all my diving equipment including the 80cuft tank. Off course I was very confident on my skill. So I started to go down and everything was good and well until the first hundred ft went by, then I started to pick up speed and the only way to slow down, at list the only way that I could think of at that moment was to put a turn of rope on my leg. I did slow down all right and got to the bottom with a nice rope burn on my chin.
From the start you get captivated by the beauty of this place, the colour of the water is a kind of aquamarine blue, very beautiful and very strange, but when you get to the small beach at the bottom, that’s a real whoa!!! Moment, the blue of the water reflects on the cavern zone in an incredible kaleidoscope of colour.
12:00 am Any way, the dive went whit out incident, the cavern goes all the way to 50m and there is the entrance to the cave. We where as far as the entrance, I give the signal to turn around and we started a very slow and beautiful accent to the surface, every body got there whit at list 300 psi on the 80’s
So we got out of the water change to dry clothes and started packing preparing for the climb out. Here it got interesting.
2:00 p.m. A friend, less call him diver Number two. Started to climb first, He is a very skilful caver and very fast climber, he uses a walker system, so he went out first and I was to be the last out. The non-divers went next. I was finishing the preparations to start sending equipment up when I heard a terrible scream.
3:00pm There where 2 persons on top all ready, number two and less call the other one number three and 4 climbing tandem two on each rope of this four three where women. All four where immersed in a swamp of killer bees.
I immediately started to put on my wetsuit and indicated the others to do likewise, In the mean time number two hearing the screams went to the edge again to see what was happening.
After trying to give directions on what to do to the two top women from now W1 and W2 and at this time stating to receive also quite a few stings him self, he decided to rappel down some 8m to them to try to help and so he did, put a third rope went down quickly connect W1 to his system, cut the safety lines and climb up. He did this two time by the second time he started to vomit so after the second rescue he went into his SUV an X-terra and made a call for help (thank god we had cell signal).
In the mean time I was down there trying to instruct the two people remaining on the ropes how to changeover from the accending configuration to descending mode. One of them W3 was about 60m from the ground and the other M1 at about 40m up. They couldn’t move, every time they try something the bees will sting.
So I decided to climb up, I and a friend D2 started climbing the ropes, got to M1, I made the change from climb configuration to decent, connected him to my harness and D2 cut him away and down we went.
Fortunately one of the remaining diver on the bottom of the sink was a medical student. So he started to treat the anaphylactic shock from M1, I was making ready to start climbing again.
In the mean time number two got really sick and his desperation try to move the X-terra, by the way did I mention that the X-terra was our main anchor point, well it was. So number two in his shocked mind thought that he could just drive and pull the ropes whit people and all….. Wrong.
3:30pm I was about to do climb rescue number two when the ropes starting to dancing around and move up about 3 meters. Well that was it for the rescue attempt, I couldn’t trust the anchors and as hard as it felt, rule #1 is not to become victim #2.
So I walked back to try to help in the treatment of M1 and to occupy my self in order not to hear the sobs and pleads for help from W3 hanging 60m from the ground and in shock all ready.
Well M1 was non-responsive, started to shake, lost sphincter control and had abnormal breathing. We started ventilating, at about that time I heard the first ambulances and fire trucks.
4:00pm I was getting kind of mad because no body was even trying to communicate with us and was very very worried about W3 that was still hanging and looked unresponsive.
At about 4:15 things starting to happen real fast. I first hear and then saw the rescue helicopter from civil services arriving, now I knew we where in good hands.
I letter learn that on top the bees where attacking anything that moves whit in 100 meters of the sinkhole, a few minutes later about 4:20pm I saw some movement on the ropes and this time for real, unknown to me there where like 50 people between rurales, fireman and other pulling the rope to get to W3 to the top, lucky we didn’t put a rebelay on the line.
So finally W3 was up and I heard another ambulance going away (about 5:30) It was to be a long night yet.
By coincidence knew some of the rescuers including the guy in charge (There are just so many crazies in this parts so we know each other)
They send down a radio and I started to co-ordinate for them from the bottom.
About 2:30 am I am the last one coming out from El Pozo de el Gavilan, pulling with me the last tank, very tired and very worried, next stop the hospital (small town in northern Mexico about 30 min drive) to see about my friends.
Epilogue
Number two spend a night and a day in the hospital on anabolic treatment. Convalescent for about two weeks.
W1 over 600 bee stings 3 days in hospital
W2 latter I learn that she was the one who precipitated the attack over 1,000 bee stings and two weeks in the hospital
M1 about 400 bee stings 3 days in the hospital and two weeks convalescing
W3 1 week in intensive care, 2 weeks in hospital then again two more days in ICU due to a blood cloth and over 1,500 bee stings, still recovering to this day.
Me I am happy but I don’t like those little bees any more.
I post this because all though it could be some thing to learn from, bees are a present danger when doing sinkholes and also I learn a lot on this one. I hope it gives you some lessons on what not to do.
I will elaborate latter.
Cheers and safe caving all.
