Abstract
The degree of soil development in glacial deposits in the Fremont Lake area (FLA) and Bull Lake type area (BLTA) on opposite sides of the Wind River Range of western Wyoming is chiefly influenced by the ages of the parent materials although other soil-forming factors are important. Soil morphology, clay content, and calcium carbonate content are useful in distinguishing moraines of the Bull Lake glaciation (about 140 to 150 ka) from those of the Pinedale glaciation (about 14 to 35 ka) in these areas. In the FLA, soils in Bull Lake deposits have an average Profile Development Index (PDI) of 39 index-cm and average 15% clay and 7% calcium carbonate (CaCO3), and soils in Pinedale deposits have an average PDI of 25 index-cm and average 6% clay and 1% CaCO3. In the BLTA, soils in Bull Lake deposits have an average PDI of 26 index-cm and average 12% clay and 17% CaCO3, and soils in Pinedale deposits have an average PDI of 20 index-cm and average 9% clay and 11% CaCO3. Differences in soils of the same age between the two areas permit an evaluation of the influences of climate, texture and composition of the parent material, and surface erosion.
