Glaciological investigations of the Upper Fremont Glacier in the Wind River Range of Wyoming were conducted during 1990-1991. The glaciological data will provide baseline information for monitoring future changes to the glacier and support ongoing

The primary subject of this paper is a test of optical dating using sand-sized quartz grains from an independently well-dated Holocene dune sequence from the Ferris dune field, Clear Creek, Wyoming. The use of a stratigraphic sequence provides

This study aims to establish the timing of strath formation and review the mechanisms for terrace formation in rivers that drain Wyoming's Laramie Range. They provide evidence for terrace formation in a river that was distally glaciated, and one
Data from airborne air-sensing probes reveal wave structures in the planetary boundary layer of the atmosphere in the wind corridor of south-central Wyoming. The airflow, which is nearly laminar throughout much of the region, responds in a series
of resonant lee waves when it encounters topographic obstacles. Gravity waves and turbulent mixing are associated with a downward transport of vertical momentum and occur in the region of accelerated windflow in the central Wyoming wind corridor. Kelvin
-Helmholtz waves are prevalent in the area of hydraulic jump at Windy Gap. Understanding of such waves and their controls is essential to siting of wind-energy systems in high-wind regions like the Wyoming wind corridor and in interpreting the mechanisms

Quartzite artifacts and debris occurring on pediments near Pinedale (Wyoming) include cobbles from which multiple flakes have been removed by percussion. Some of the specimens have been polished and abraded by wind-blown sand. Neither feature
