Abstract

Field and laboratory analyses of soils developed on piedmont and alpine moraines suggest a temporal discrepancy exists in the termination of Pinedale (> 10,000 yr B.P.) glaciation from the northern to the southern region of the Wind River Range of Wyoming. Two radiocarbon dates reported from separate regions of the mountains support the soils relationships, and indicate ice retreated from the southern piedmont approximately 3,000 years earlier than ice retreat is recorded in the north. Together, the differences in soil development and the range of reported dates suggest the southern moraines are older, and reflect an unequal distribution of glacial ice in the mountains during the terminal Pinedale.
