You may or may not have seen my previous shots of cenotes, the natural sinkholes of the Yucatan Peninsula, Mexico. One was like an idyllic lagoon, the other a crystal clear jungle pool. But there are other other kinds of cenotes too, like this one above - narrow and deep, descending into subterranean caverns, either fully or partially flooded, where in the dim light you can see amazing formations in the limestone rock, and stalactites & stalagmites too. Inhabited only it seems by bats and spiders on the rock faces but no visible life (aside from snorkellers and divers) in the water. All cenotes however have one thing in common, all are connected by underground rivers which flow eventually either East to the Caribbean Sea or West to the Gulf of Mexico. Having clambered down the ladder to a small wooden dock below and taken a few shots, my camera was safely double sealed in a waterproof bag carried by Antonio the guide. We put our masks on and slipped into the water, swimming through the cave and into an even dimmer lit tunnel with just a few feet of air and then a rock ceiling above, and who knows what depth of water below. After about 50 yards we emerged into a brightly lit deep crater, caused by a large jungle tree on the surface having collapsed the limestone ceiling and now continuing to grow at the bottom of the crater, with all kinds of ferny and reedy plants growing amongst and around its roots. Then into another tunnel and finally emerging again into yet another crater, full of plant life, with wooden steps leading to surface. These we climbed to the surface as Antonio explained the meaning of this particular cenote's name. It seems that many bones of deer and other mammals have been found in the craters. The explanation being they had most likely stumbled into the surface holes at night and fallen then become trapped below. Cenote Pet Cemetery was actually named by cave divers, apparently well known for their slightly twisted view on the world.
