Neogene tectonics and geomorphology of the eastern Uinta Mountains in Utah, Colorado, and Wyoming

Abstract

A recent reevaluation of the Bishop Conglomerate in the Eastern Uinta Mountains region helps clarify how the conglomerate relates to the Browns Park Formation and, in turn, how both formations relate to middle Tertiary tectonic activity and late Tertiary and Quaternary drainage adjustments. Field relations indicate widely divergent histories for the two formations: They are separated in their type areas by great topographic discontinuity, but east of the Uinta Mountains, between Cross Mountain and Maybell, Colo., the Browns Park lies directly on the Bishop.
