The Plio-Pleistocene Quemado Formation of west-central New Mexico
Steven M. Cather and William C. McIntosh


The Plio-Pleistocene Quemado Formation (new name) consists of 29.5 m of volcaniclastic and siliciclastic sandstone and conglomerate at its type section in northwestern Catron County, New Mexico. The Quemado ranges in age from ~4 to <1 Ma, and consists of fluvial deposits that accumulated in several basin/paleovalley systems in upper reaches of tributaries to the ancestral Little Colorado River. The Quemado Formation is, at least in part, correlative with the upper part of the Bidahochi Formation.
