Summary:

Pg. D111. Paiute formation. Consists of at least 40 feet of alluvial and colluvial gravel. Overlies andesitic and basaltic lavas of Pliocene and early Pleistocene(?) age with pronounced unconformity; underlies pre-Lake Lahontan soil and earliest deposits of Lake Lahontan (Eetza formation, new) with slight or no disconformity. Age is late Pleistocene.
Type locality: exposure along middle part of Paiute Wash, in sec. 8, T. 16 N., R. 31 E., near Fallon, Churchill Co., southern NV. Named from Paiute Wash. Exposed locally, above 3,960 ft altitude, on piedmonts and in highlands.

Summary:

Pg. 23-24. Paiute Formation. Bulk of unit is alluvial-fan gravel exposed above 3,960 feet elevation. Overlies Bunejug formation (new) and older rocks with pronounced unconformity. Conformably underlies Cocoon soil which in turn underlies Eetza formation. Shown on geologic maps of Carson Lake and Fallon 15-min quadrangles as of Pleistocene age. Is youngest sedimentary unit of pre-Lake Lahontan age.
Type locality: Paiute Wash, in sec. 8, T. 16 N., R. 31 E., on piedmont northeast of Cocoon Mountains, Churchill Co., southern NV.
