Is 22.9 ft thick at type where it consists of: brown, massive to banded, silt at base; a middle pebbly, loose, clean, fine grained sand with some angular to subangular pebbles derived from crystalline, Paleozoic, and Tertiary rocks; and an upper brown, massive, thin-bedded, clayey silt. Unconformably overlies Tertiary conglomerate and underlies a white to brown soil. Mapped (geologic map) in a very limited area slightly more than one-quarter mile narrow band for a short distance west of Bull Lake. This till is older than any of the previously recognized tills in the area. Also called Washakie Point glaciation. Occupies terrace 760 ft above the Wind River. Regionally correlates with the Rocky Flats Alluvium and the Nebraskan Till. Of Pleistocene, pre-Wisconsin age. Designated both Washakie Point Till and Washakie Point glaciation.
