Soils of Post-Audubon Age, Teton Glacier Area, Wyoming

Abstract

Glacial deposits of late Neoglacial age in the Teton Range are dated by use of relative age-dating criteria. Soils of post-Audubon (1,850 to 950 BP) and post-Gannett Peak (300 to 100 BP) age are recognized on moraine surfaces. Morphological, physical, and chemical characteristics of the post-Audubon soils are discussed and correlated with soils of the Colorado Front Range. Recent geomorphological and pedological investigations suggest that glacier fluctuations in the Teton Range during the late Neoglacial may be broadly synchronous with those defined elsewhere in the Rocky Mountains.
