Abstract

The Wind River basin was part of the stable shelf that lay east of the Cordilleran geosyncline during Paleozoic and Mesozoic time. Sedimentary rocks representing all systems except possibly the Silurian are briefly described and related to the tectonic evolution of this region. The tectonic sequence culminated in the intense folding and faulting of the Laramide orogeny beginning in latest Cretaceous and extending into early Eocene time. The later Tertiary records basin filling, followed by late Pliocene and Pleistocene epeirogenic uplift that initiated a long period of degradation which still continues.
