Peale, A.C., 1879, Report on the geology of the Green River district [Wyoming], IN Hayden, F.V., Eleventh annual report of the United States Geological and Geographical Survey of the Territories, embracing Idaho and Wyoming, being a report of progress of the exploration for the year 1877; Part I, Geology and paleontology: U.S. Geological and Geographical Survey of the Territories (Hayden), Annual Report, 11, p. 509-646, pls. 47-66, 66a, 67-75, 75a, 76.


Summary:

Pg. 603-606, 634, 635, 640, 641. Cache Valley group. Soft marls and sands, best exposed in north side of Cache Valley [northeastern Utah and southeastern Idaho] and on Bear River below the middle canyon. They are somewhat variegated and horizontal in position. Deposited in lake, which shows a number of levels. Possibly of same age as Malade Valley group and possibly older. Age is Pliocene(?). [Now [ca. 1938] considered probably of same age as Salt Lake formation.]

Summary:

Pg. 73, 75 (fig. 2). Formation at top of Salt Lake group. Overlies West Spring formation (new). Thickness 1,000 to 2,000 feet. [Age is middle and late Pliocene.]

Summary:

Pg. 1, 2, 6-7. Redefined to /include West Spring formation. Thickness 7,674 feet. Overlies Collinston conglomerate; underlies Mink Creek conglomerate (new). [Age is] Miocene and Pliocene.
[Assigning a formation to a formation is in conflict with rank hierarchy of formal lithostratigraphic units (see CSN, 1933). Perhaps the strata included in West Spring formation by previous workers, are reallocated to Cache Valley formation in this report?]
