Submerged Shorelines of Jackson Lake, Wyoming: Do They Exist and Define Postglacial Deformation on the Teton Fault

Abstract

The Teton fault is one of the most active normal faults in the world, as attested by the precipitous high front of the Teton Range. Following glacial recession about 15,000 years ago (Porter and others, 1983), offset on the Teton fault southwest of Jackson Lake has totaled 60-80 feet (19-24 m) (Gilbert and others, 1983). In less than the last 9 million years, offset on the Teton fault has totaled 25,000-30,000 ft (7,000-9,000 m) (Love and Reed, 1971).
