 On 10/30/2012 Harvey and I hiked the Upper Las Vegas Wash area looking for the location of the the 1962 paleontological dig that uncovered hundreds of old fossils. Upper Las Vegas Wash is a series of aprons — bajadas — that fringe the rugged ranges of the Sheep Mountain Range. Though this part of the wash is normally dry, except during the monsoon season, it has been accumulating sediment for many centuries, leaving a sedimentary record of conditions and ecosystems covering millions of years. Unfortunately we didn’t find anything of interest, not even a shell, let along examples of extinct mammoths and ground sloth fossils.
