Named	Greater Green River basin	Sandstone Conglomerate Shale Clay

Summary:
Named as a member (one of four) of the Green River formation for exposures in Laney Rim and Cathedral Bluffs, which form the northwest edge of the Washakie basin in Sweetwater Co, WY, Greater Green River basin. The feature Cathedral Bluffs lies in T19N, Rs95 and 96W. Mapped continuously from Cathedral Bluffs on both sides of Washakie basin into Carbon Co, WY and south into Moffat Co, CO, also in the Greater Green River basin. No type locality designated. Overlies Tipton shale member (new) of the Green River. Underlies Laney shale member (new) of the Green River unconformably. Geologic map. Stratigraphic charts. Measured sections. Ranges from 0 to 1,500 ft thick. One section near Lookout Mountain, WY has 1,200 to 1,500 ft section of Cathedral Bluffs which is described as brilliant colored--red or red-purple with light green bands--"clay and sand." The member otherwise described as containing red or varicolored conglomeratic sandstone, shale, and clay. Of Eocene age.

Summary:
Stratigraphic rank term changed from Cathedral Bluffs redbeds member to Cathedral Bluffs tongue. Formation association changed from Green River formation to Wasatch formation. Mapped (geologic map) around Rock Springs uplift, Sweetwater Co, WY into Vermilion Creek area, Moffat Co, CO in the Greater Green River basin. Is about 1,200 ft thick in vicinity of Lookout Mountain, CO. Overlies and intertongues with Tipton tongue of Green River formation (formerly Tipton shale member of Green River). Underlies Laney shale member of Green River formation. Of Eocene age.

Revised Overview	Greater Green River basin

Summary:
Is a tongue of the Wasatch formation that tongues north toward Cyclone Rim, Great Divide basin, Sweetwater Co, WY in the Greater Green River basin into the newly named Battle Spring formation, a coarse-grained to pebbly arkosic sandstone. Battle Spring at Cyclone Rim is equivalent to and intertongues with all the parts of the Green River and Wasatch formations. Estimated to be 1,400 to 1,600 ft thick near Cyclone Rim where it underlies Morrow Creek member of the Green River formation. To south it underlies the Morrow Creek equivalent, the Laney shale member of the Green River. Eroded from central part of Great Divide basin. Fossils scarce. Inferred middle Eocene age. Cross section.

Areal limits Revised	Greater Green River basin

Summary:
Cathedral Bluffs Tongue of Wasatch Formation areally extended to the west margin of the Greater Green River basin and applied to rocks above Wilkins Peak Tongue of Green River Formation and unconformably below Laney Member of Green River. This interval of rock was named New Fork Tongue of Wasatch by Donavan (1950). It was later designated upper tongue of Wasatch by Oriel (1961) and by Lawrence (1963). Sullivan (1980) named it Desertion Point Tongue of Wasatch. These different names have been applied to the same rocks. The name Cathedral Bluffs was defined first and has precedence. Stratigraphic diagrams, measured sections. Of early and middle Eocene age; NOTHARCTUS found 42 ft above base at the Pinnacles (sec 25, T24N, R101W); HYRACOTHERIUM found near Wilkins Peak-Cathedral Bluffs contact in sec 24, T24N, R99W; both fossils are early Eocene perissodactyls.

Areal limits Overview	Greater Green River basin

Summary:
Isopach map (fig 27) shows areal extent within Greater Green River basin, WY and CO. Cathedral Bluffs (Wasatch Formation) intertongues with and replaced by Wilkins Peak Member of Green River Formation from margins toward center of basin. Basal part intertongues with underlying Tipton Shale Member of Green River; upper part intertongues with overlying Laney and Godiva Rim Members of Green River. Intertongues and replaced by Butte Spring Formation in northeast part of basin. Merges with main body of Wasatch in southeast and southwest parts of basin. Ranges in thickness from 0-2000 ft; maximum thickness is near center of Washakie basin and in western Sand Wash basin. Stratigraphic chart; cross sections. Eocene age.
