The Climate and Hydrologic History of Southern Nevada During Late Quaternary

ably the penultimate major wet-climate periods. Spring deposits at Crater Flat and at the Lathrop Wells Diatomite 20 krn south of Yucca Mountain and paleowetland deposits near the Amargosa River show that discharge occurred between about 40,000 and 8,000 years before the present. The discharge, at least in part, came from the regional aquifer when the water tables rose to a maximum of about 100 m above present levels, as indicated from the depth to regional ground water at the Lathrop Wells diatomite site.
