First published use as a name applied to a 5000+/-ft thick conglomerate and agglomerate unconformably? above a Miocene basic breccia and unconformably below Pleistocene till. The conglomerate and agglomerate were locally derived. Thin fresh water limestone beds, too. Fossil horse tooth of late Miocene or early Pliocene age identified. Differs from Pass Peak conglomerate as to source area. Pass Peak was derived largely from local Mesozoic and Paleozoic rocks. [Name was first used in an abstract by Eardley, 1942.] Stratigraphic chart. Footnote to chart says that the Camp Davis "flanks the Hoback Range" which lies south of the Gros Ventre Range in the Greater Green River basin.

First used by Eardley (1944) on a privately printed map. Brief descriptions published by several authors 1949-1955. [This paper has first comprehensive description.] Named for Camp Davis, University of Michigan camp, along Hoback River. Type section along east side U.S. Hwy 187, sec 29, T39N, R115W, Teton Co, WY, Yellowstone province. Type abundantly fossiliferous but only basal 450 ft exposed. Thickest most complete section on north side of Horse Creek between sec 13, T39N, R116W northeast to secs 7 and 8, T39N, R115W where is 5,600 ft thick. Present along Snake and Hoback Rivers; may be present southwest of Gros Ventre Mountains. Some high-level gravels in Gros Ventre have been assigned to Camp Davis. At type, lower 250 ft are light-gray, hard, cliff-forming conglomerate (chiefly Paleozoic limestone and dolomite clasts, some pre-Cambrian clasts in gray sandy limestone matrix). Overlying white, gray, pink heterogeneous sequence of limestone, claystone, tuff, pumicite, conglomerate and diatomite 200 ft thick succeeded by: 1) poorly exposed chocolate-colored claystone, one white tuff, interbedded, poorly consolidated conglomerate (derived from Tensleep sandstone, Madison limestone); 2) 4,000 ft red conglomerate (derived from Triassic, Paleozoic and few from pre-Cambrian rocks; coarsest at top). Pliohippus tooth-early Pliocene age. Also has mollusks, ostracodes, diatomite. Younger than Colter formation; older than Teewinot formation.

Age changed from early Pliocene to late Miocene on basis of placement of the Miocene-Pliocene boundary at 5 m.y. Also has mollusks, pollen, and sparse vertebrate fossils of early late Miocene age. Area reported on is in the Yellowstone province.
