The Tecolote Hills in the north-central Lincoln County, New Mexico, consist of Permian, Triassic, and Cretaceous sedimentary strata intruded by early Tertiary (?) sills, dikes, and laccoliths. A partial section of the Permian Yeso formation, measured thickness 380 feet, is exposed and is overlain conformably by the Glorieta sandstone member of Permian San Andres formation. This sandstone thins, at least locally, to the south and intertongues with San Andres limestone. The maximum thickness of the Glorieta sandstone is about 215 feet. It is overlain by a 300-foot thickness of San Andres rocks, further divisible into a lower limestone member and an upper gypsum member. The Permian Bernal formation, which is about 50 feet thick, conformably overlies the San Andres formation. Unconformably overlaying the Bernal formation is a 300-foor section of the Triassic Dockum group. Unconformably overlaying the Triassic rocks is a 30-foot section of the Cretaceous Dakota sandstone.
