Como Bluff Anticline, Albany and Carbon Counties, Wyoming

Abstract

Como Bluff anticline is a westward-plunging, asymmetric fold extending across the east-central part of the Laramie Basin. The northeast axial trend of the anticline is nearly normal to the axial trends of the Laramie Basin and the Laramie Range. The northwest and steeper flank of the anticline is faulted by the North Como thrust. The thrust plane dips southeast. The fold probably originated from northwest-southeast compressive stresses. A geologic map of the western quarter of the anticline, interpretative structure sections, and detailed stratigraphic sections are given. The area has been made geologically famous by successful excavations for dinosaurs and other Jurassic reptiles.
