Boots

Description: Pair of brown suede boots. Almost knee-high, the boots are constructed as slip-on rounded-toe shoes or moccasins with added segments on the quarter to create the length of the boots. At the top, the suede of the boots is folded over outwards forming a pocket for a drawstring around top and a band of suede fringe around the outside of the boot. Indistinct trademark/logo stamped on sole. Illegible stamped mark inside boots. Referred to as "Squaw Boots", these were worn by the donor who acquired them in 1968 from the Fishing Bridge Store, in Yellowstone National Park.

Studies Regarding the Role of Wyoming Natural Gas in Precipitating Primary uranium Minerals from Pregnant Solutions

Description: Abstract: This project was designed to test the chemical feasibility of depositing of depositing a primary uranium mineral from a pregnant solution by exposing the solution to natural gas in an environment favorable to such deposition.

Reconnaissance for Uraniferous Rocks in Northeastern Wind River Basin, Wyoming

Description: From abstract: A reconnaissance search for uraniferous rocks in the northeastern part of the Wind River Basin was made in July and August 1951 in the course of other work. In addition to Tertiary tuffs and associated lignite, coal, and carbonaceous rocks, some radioactivity anomalies, chiefly in granite, which had been detected by airborne equipment in November 1950, were checked on the ground. A tuff of middle or late Eocene age containing 0.003 percent uranium was as high in uranium as any rock found.

Uranophane at Silver Cliff Mine, Lusk, Wyoming

Description: Abstract: The uranium deposit at the Silver Cliff mine near Lusk, Wyo., consists primarily of uranophane which occurs as fracture fillings and small replacement pockets in faulted and fractured calcareous sandstone of Cambrian(?) age. The country rock in the vicinity of the mine is schist of pre-Cambrian age intruded by pegmatite dikes and is unconformably overlain by almost horizontal sandstone of Cambrian(?) age. The mine is on the southern end of the Lusk Dome, a local structure probably related to the Hartville uplift. In the immediate vicinity of the mine, the dome is cut by the Silver Cliff fault, a north-trending high-angle reverse fault about 1,200 feet in length with a stratigraphic throw of 70 feet. Uranophane, metatorbernite, pitchblende, calcite, native silver, native copper, chalcocite, azurite, malachite, chrysocolla, and cuprite have been deposited in fractured sandstone. The fault was probably mineralized throughout its length, but because of erosion, the mineralized zone is discontinuous. The principal ore body is about 800 feet long. The width and depth of the mineralized zone are not accurately known but are at least 20 feet and 60 feet respectively. The uranium content of material sampled in the mine ranges from 0.001 to 0.23 percent uranium, whereas dump samples range from 0.076 to 3.39 percent uranium.

Longwall Gate Road Stability in a Steeply Pitching Thick Coal Seam with a Weak Roof

Description: The U.S. Bureau of Mines (USBM) conducted ground pressure analysis of a wide abutment-type chain pillar in a two-entry gate road of a Western U.S. coal mine with an extremely weak immediate roof. About 15 m of fragile, low-strength mudstone lies between the seam and the lowest competent roof member. Three- and two-entry gate road designs with several pillar sizes and various secondary support systems have been employed to improve tailgate-entry stability, with varying results. This report discusses gate road layout and performance and secondary support effectiveness. The results of the pillar pressure study are compared to pillar loading predicted by a widely used pillar design method and to similar studies in other mines. A stability evaluation of the most recent longwall headgate, using the USBM Analysis of Longwall Pillar Stability (ALPS) method, indicates marginal stability in first-panel mining and instability in second-panel mining. The ALPS method and the USBM Coal Mine Roof Rating system are used to evaluate tailgate-mining stability of the previous gate roads and to determine pillar and entry width and top coal thickness criteria for tailgate stability in future panels.

Preliminary Report on Uranium-Bearing Pliocene (?) Rocks in the Split Rock Area, Central Wyoming

Description: From abstract: A sequence of slightly radioactive Pliocene(?) rocks in the Split Rock area of central Wyoming is at least 600 feet thick, underlies an area of more than 25 square miles, and consists of alternating beds of tuffaceous shale, sandstone, and pumicite. Only a small part of the section has been examined. In addition to the uranium content of the strata, there has been secondary concentration of uranium in brecciated limestone similar to spring deposits that could be of Pliocene or Pleistocene age.

Preliminary Report of the Results of Reconnaissance for Uraniferous Materials in the Powder River Basin, Wyoming

Description: From introduction: During three months of the summer of 1952, a geologic and radiometric reconnaissance examination for uraniferous materials in the peripheral parts of the Powder River structural basin in northeastern Wyoming (fig. 1) was made by the Survey on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. The purpose was to find, describe, locate, and sample deposits of uraniferous or radioactive materials other than those in the central part of the Powder River Basin in the general vicinity of the Pumpkin Buttes.

Geology of Devils Tower National Monument, Wyoming

Description: From abstract: Devils Tower is a steep-sided mass of igneous rock that rises above the surrounding hills and the valley of the Belle Fourche River in Crook County, Wyo. It is composed of a crystalline rock, classified as phonolite porphyry, that when fresh is gray but which weathers to green or brown. Vertical joints divide the rock mass into polygonal columns that extend from just above the base to the top of the Tower.
