What at first seemed to be a hill proves to be a vine-covered and fern-topped wall. More walls rise above the first in a series of titanic steps as the great ziggurat rises out of the jungle to rear its head from the forest canopy. A glint up there catches your eye. It’s hard to see from your vantage point, but someone wearing gold stands at the top, and now you spy a thin wisp of smoke up there as well.
