Pg. 32, 41. Deadman limestone member of Nugget sandstone. Dense purplish-gray limestone of almost lithographic quality, with subordinate amounts of gray and greenish chert. Thickness 150+/- feet. Overlies Higham grit member of Nugget and underlies Wood shale member of Nugget. No fossils. [Age is Triassic(?).]
Named from Deadman Creek, in northeast part of T. 4 S., R. 38 E., Boise meridian, in northeast part of Fort Hall Indian Reservation, Bingham Co., southeastern ID, near headwaters of which it is exposed.

Pg. 29, 52. Treated Deadman limestone, Wood shale, and Higham grit as distinct formations, and restricted Nugget sandstone to upper part ("main sandstone member") of Nugget sandstone as recognized by him in previous reports. This is present [ca. 1938] generally accepted definition. Age is Triassic(?). Report includes geologic map, stratigraphic table, history of nomenclature chart.

Pg. 17, 34-35, pl. 1. Deadman limestone. Mapped in Ammon and Paradise Valley quadrangles. Thickness about 150 feet. Overlies Higham grit and underlies Wood shale. Age is Triassic(?). Type locality designated.
Type locality: Deadman Creek in northeastern part of T. 4 S., R. 38 E., Paradise Valley quadrangle, ID, where formation is crossed by the creek and extends northwestward along the ridge parallel to and northeast of prominent band of Higham grit. Named from Deadman Creek.

Pg. 180-181. Mansfield (1927, USGS Prof. Paper 152) recognized following sequence of beds between Thaynes and Nugget formations; Timothy sandstone, Higham grit, Deadman limestone, and Wood shale. These units are distinct lithologically and are equivalent to Ankareh formation of Wasatch and Uinta Mountains of western Wyoming. In present report, Timothy sandstone is considered uppermost member of Thaynes. Higham grit and Deadman limestone are recognized as independent formations and Wood shale is considered westward extending tongue of Ankareh formation. At type area, the Deadman is 150 feet thick and directly overlies Higham grit. [Age is Late Triassic.]

Source: US geologic names lexicon (USGS Bull. 1200, p. 1056).
Deadman Limestone. Consists of (ascending): (1) red-brown, gray, purple, and buff sandstone and siltstone with a few thin limestone beds; (2) gray, commonly mottled green, red, purple crystalline limestone containing gray and pale green chert nodules; and (3) red, brown to red-gray calcareous shale and siltstone with some thin lithographic gray limestone beds in upper part. Thickness about 280 feet. Occurs above Higham Grit and below Wood Shale Tongue of Ankareh Formation. Age is Late Triassic.

Name applied to a 150 ft thick white, pink-, green-, to purple-gray, dense limestone. Contains minor chert. Overlies Higham Grit. Underlies Wood Shale. Mapped as a thin band in east-central part of quad. in Bingham Co., ID in the Snake River basin. Assigned to the Upper Triassic.
