Named for exposures on the west side of Continental Peak, sec 29, T27N, R100W, Fremont Co, WY in the Wind River basin. Type section designated near center of sec 35, T27N, R101W where a 251 ft thick section measured. Disconformably overlies Bridger formation. Disconformably underlies Beaver Divide conglomerate member (new) of Chadron formation. Consists of green to gray volcanic ash, and red, gray, brown sandstone. The sandstone may be fine grained, coarse grained, ashy, argillaceous, cross-bedded, and contain nodular and discoidal concretions up to 2 ft thick. Divided into two parts by a disconformity at type. Is 145 ft thick in section measured north of Oregon Butte in sec 2, T26N, R101W, Sweetwater Co, WY in the Greater Green River basin. Geologic map; cross sections; stratigraphic table. Mapped only in the Continental Peak and Oregon Buttes areas. Has been recognized in the Red Desert to east and to northwest at Elk Mountain and Tabernacle Butte. Fossils (gastropod, turtle bones, alga, ostracodes) found at several localities.

Term Continental Peak Formation should not be applied to the middle and upper Eocene rocks of the Beaver Rim area or of the Great Divide basin, WY, Greater Green River basin, because the rocks of these areas accumulated in a different structural basin than the Continental Peak. Name Wagon Bed Formation introduced for the middle and upper Eocene rocks of these areas. Wagon Bed is divided in 6 units; unit 1 is the oldest unit. Continental Peak is thought to be equivalent at least to unit 5 of the Wagon Bed.

Mapped in several outcrops in the center part of the study area, Fremont Co, WY in the Wind River basin. Consists of pink, poorly sorted, medium- to coarse-grained tuffaceous sandstone. Has a 0-35 ft thick conglomerate near base of cobbles of Paleozoic limestone, chert and quartzite in a fine-grained, limy, pink sandstone matrix. Formation is as much as 350 ft thick. Unconformably overlies Bridger Formation. Unconformably underlies unnamed upper Eocene conglomerate. Assigned to the upper Eocene.
