Summary:

Unit is named the Walker Lake Bed of the Salt Wells Member of the Mono Basin Formation. Is located in the Lake Lahontan area, NV. Consists of a layer of rhyolitic tephra about 1 cm thick that contains glass-encased biotite phenocrysts and has a high silica, low magnesium content. May represent a dense, crystal-rich fraction of the Turupah Flat Bed (new) of the Salt Wells. Source is believed to be Mono basin because of its geographic distribution south of Carson Sink. Age is Holocene, about 1.2 ka. (B1565)
