A number of years ago I had the pleasure of visiting the Mayan ruins in Copan, Honduras. It was an amazing experience.....
Tikal is enormous, a 3.5 hour long walking tour in which most of your time is spent walking. They also have a large number of athletic Guatemalan girls as tour guides.
For years it was assumed that Tikal had to be the capital of their empire, until a geologist was inspecting an unusual topographical feature, a ridgeline about 30 miles north of there, unique in the area, which is dotted with small volcanoes. After poking around on it for a while, he said it’s not natural, it’s a buried city.
Archeologists threw up their hands, because they would need thousands of workers and many millions of dollars just to unearth it, much less restore it. We’re too busy. Maybe in a few hundred years.
