No. 11: Summer 1980
If humans first populated North America via the Bering land bridge 10-20,000 years ago, how did human bones and artifacts get buried under a 50,000-year-old alluvial fan in California? Dogma demands that such finds be discredited. Thus, "Pleistocene Man at San Diego," the Calaveras Skull, and dozens of other archeological anomalies have been dismissed as the hoaxes and misidentifications of nonprofessionals. The latest hint of truly ancient man in America came after heavy rains in 1976 cut through 21 meters of deposits at Yuha Pinto Wash, just north of the Mexican border in California. The artifacts, still firmly in place, and associated bones are undeniably human. The overlying sediments are dated at more than 50,000 years old.
