This is a remarkable feature which as the discoverer (K. Laney) justifiably states, "Were this found anywhere on Earth, we'd surely be digging into it." If other anomalous features in the same area could be identified, this would provide corroborative support that we may indeed be looking at an artificial construction.


The pronounced tetrahedral shape. Similarity in base size with the Great Pyramid at Giza (which is 230 m / 756 ft), suggesting perhaps a prehistoric cultural connection.


A hill sculpted by erosive winds.
