Fantastic Pit at Ellison's Cave, Georgia Ellison's Cave far under Pigeon Mountain in northwest Georgia. The cave's "Fantastic Pit," seen here, is the deepest cave drop in the continental United States at a staggering 586 vertical feet vertical meters).
I went here and stood over the falls on a rock that stuck out, no guard rails and you can stand in the water not far from the edge. So beautiful! Kaieteur Falls, a waterfall on the Potaro River in central Guyana, South America.
