On 02/21/2018 Bob Croke, Jim Herring, Ron Ziance, and I drove to the Aliante Pkwy location to enter the Tule Springs Archaeological Site in the TUSK National Monument in search of the trenches dug during the "big dig". As we entered the monument, we headed out across the barren Las Vegas Wash in a north westerly direction. Once we reached the power line we turned west until we encountered what we thought look liked a large trench that ran north to south. Though we never found any fossils, we did find some seashells and snails. Click her for more pictures and a description ... Tule Springs Archaeological Site (TUSK) - Trip Notes for 02/21/2018).
