There are still hundreds of Mayan pyramids hidden in the forests of Quintana Roo. One of these is located very close to where we banded some growth trees in Tres Garantias (see Selva Maya II and Selva Maya III). It's hard to capture this type of thing in a video, but look for the square cut stones, the arch, and the interior room. The seedlings shown at the end are, not surprisingly, Brosimum alicastrum (see The Curious Case of Brosimum alicastrum). [NOTE: Thanks to Luis Chai for showing this to us].
