ScienceDaily for July 22, 2010 reported on research in fresh-water pools considered sacred by Mayan.
Steering clear of crocodiles and navigating around massive submerged trees, a team of divers began mapping some of the 25 freshwater pools of Cara Blanca, Belize, which were important to the ancient Maya. In three weeks this May, the divers found fossilized
animal remains, bits of pottery and -- in the largest pool explored -- an enormous underwater cave.
