Cenote Snorkeling

The other day I went on a guided tour of some of the more impressive of the thousands of cenotes here in Yucatan. This one was quite large and maybe a hundred feet deep at some places. Lots of colors, greens, blues and reds, from the different layers of rocks. The water is fresh and clear. A few small fish make homes out of the cenotes, and bats can be seen and heard flying around the cave overhead.
Something that creeped me out, though, was that I found human bones. Not kidding. Some of the indigenous people used to sacrifice stuff to the cenotes because they were considered sacred. There are lots of jade trinkets on display at the anthropology museum that were found in cenotes. Another guy on the tour found a knife made of stone in this cenote, which he took with him. I left the bones there.
