No. 14: Winter 1981 Supplement
Outside Fort Morgan, Colorado, workmen digging pits for a landfill uncovered a prehistoric campsite 40 feet under the sandy bed of an ancient stream. The diggers found bones, worked flints, and burnt stones arranged in a ring. Excavations were stopped when the importance of the site became obvious. Estimates of the campsite's age were as old as 30,000 years -- a figure that would have been heresy a decade or two ago.
