On-Site At The Upper Pleistocene Sehoo Formation, Nevada

Here, the view is roughly due north to the fine silts and clays of the Upper Pleistocene Sehoo Formation, Nevada. Interbedded with the dominantly lacustrine (lake-deposited) sedimentary section are a number of volcanic ash beds; two of the more prominent ash intervals have been dated by radiometric means at roughly 24,500 and 22,000 years old, respectively.
