Named; derivation of name not stated though probably for Cedar Breaks National Park [Monument] where unit is best displayed. Type section designated along topographic noses in secs. 23, 27, T36N, R9W, Iron Co, UT. Forms "Pink Cliffs" at Cedar Breaks [Great Basin province], Bryce Canyon National Park and along margins of Table Cliff Plateau, Garfield and Kane Cos [Paradox basin and Plateau sedimentary province]; also exposed on east-facing cliffs of Pavant Mountains, Sevier Co [Wasatch uplift]. Rocks previously referred to as Wasatch Formation in southern High Plateaus and Flagstaff Formation in Pavant Mountains. At type consists of 55% calcilutite, 25% calcisiltite, 14% argillaceous calcilutite, and 6% sandstone and conglomerate; relative percentages vary laterally. Thickness ranges from 1907 ft in Pavant Range, thinning to 1434 ft at type and to 525 ft in Table Cliffs Plateau; pinches out to east. In southern High Plateaus overlies Kaiparowits Formation and underlies Brian Head Formation; in Pavant Mountains overlies North Horn Formation and underlies Green River Formation; contacts are conformable or unconformable. Measured sections; correlation of sections. Cedar Breaks-type rocks probably extend eastward to western part of San Juan Basin; also thought to extend in subsurface westward from Pavant Mountains into Great Basin. Equivalent to Claron Formation and to Flagstaff of Wasatch Plateau. Assigned Paleocene and earliest Eocene age based on correlation with Flagstaff.

Not used in this report in Paradox basin. Beds formerly assigned to Cedar Breaks now called pink limestone member of Wasatch Formation. Both Cedar Breaks and Wasatch are of Paleocene and early Eocene age.
