Creation of the Teton Landscape: The Geologic Story of Grand Teton National Park

A concise geologic account traces the origin and development of the Teton Range and its adjoining valley by examining ancient crystalline cores, sedimentary sequences, tectonic uplift along faults, and later volcanic and sedimentary events. The narrative explains how tilted crustal blocks, crustal movement, and ongoing fault activity produced dramatic relief, and how water, glaciers, and mass movements have sculpted peaks, canyons, landslides, and glacial lakes. Photographs, diagrams, and a brief appendix on geologic time and terms support clear, field-oriented explanations of the region’s rock record and continuing landscape evolution.
