The desert art, which was pecked or sometimes incised into large rock faces, depicted elephants, ostriches, giraffes, and many hunting scenes. But perhaps strangest of all was the abundance of boats depicted in the art. After all, this area was far from any body of water, says Brewer, a University of Illinois professor of archaeology and director of the Spurlock Museum in Urbana
This is rock art found in the Egyptian desert. The location is being kept secret. The art could date back to the Holocene period when the area had an abundance of water - since the art is 50 ft. up on a mountain.
