High-Pressure Granulites from the Tetons: The Earliest Record of Himalayan-Style Tectonics in the World

Abstract

In August 2004 a field party from the University of Wyoming consisting of one faculty member, two graduate students, and one undergraduate student spent two weeks mapping the basement gneisses in the area around Moose Basin. During this project we mapped an area on the pass between Moose Basin and Camp Lake (which is just west of Grand Teton National Park) in detail, made detailed traverses along the head of the cirque for about 3 km southeast of the Park boundary, and collected 44 samples for petrology (Figure 1).
