Summary:
Unit is named the Mono Basin Formation. Is exposed in the Mono Lake and Lake Lahontan areas, NV and CA. Is divided into the Carson Sink Bed (new) and the Salt Wells Member (new) which, in turn, contains the Walker Lake Bed (new) and the Turupah Flat Bed (new). Consists of tephra, the source of which is believed to be Mono basin in eastern CA because of its similarity in petrography and age to known tephra from Mono basin and its geographic distribution, which is limited to the area south of Carson Sink. Age is Pleistocene and Holocene, 35 to 0.6 ka. (B1565)
