Baldy Hill Formation
The Baldy Hill Formation is a geologic formation in northeastern New Mexico and western Oklahoma. It preserves fossils dating back to the late Triassic period.
Description
The Baldy Hill Formation is a dark purple, reddish brown, or greenish gray silty to sandy mudstone with some fine-grained sandstone. Its base is not exposed at the type section, but it is at least. It is overlain by the Travesser Formation, with the contact marked by the Cobert Canyon Sandstone Bed, a persistent layer of conglomerate beds now assigned to the Baldy Hill Formation or possibly the overlying Travesser FormationThe formation may correlate with either the Garita Creek Formation or the Los Esteros Member of the Santa Rosa Formation.
