Did the Ancient Egyptians Inhabit the Grand Canyon?

Beautiful and breathtaking, this vast cleft in the earth holds many secrets, perhaps none more mysterious than the one reported in the Phoenix Gazette, on April 5th 1909. An explorer, one G.E. Kincaid (who had served the Smithsonian for over thirty years) was reporting a startling archeological discovery.  Kincaid's boss, Professor S.A. Jordan of the Smithsonian – who were financing the expedition – was said to be enthusiastic that the find be further investigated, as it was of ‘major significance’. Kincaid had found, about 2000 feet up the canyon wall above the Colorado river – some forty-two miles upstream from the El Tovar crystal canyon – a cave entrance to a vast underground city, chiseled from the solid rock.  weblink
