I like to read about these places because often times there are artifacts that people used as talismans. Gold, serpentine, emeralds, carved whale bones and agate were all found in these Panamanian graves and there are similar places in Costa Rica. Blue Jade from a single source has been found in Costa Rica. Often these treasure troves have similar items in them. the great pyramid of Cholula is the largest pyramid by volume ever discovered yet it is unknown to most people. All kinds of things like obsidian mirrors and scepters along with other green stones like serpentine and Jade were found around there.
