Proterozoic Geology of the Granite Village Area, Albany and Laramie Counties, Wyoming, Compared with that of the Sierra Madre and Medicine Bow Mountains of Southeastern Wyoming

Description: Abstract: "Precambrian metavolcanic rocks north and south of the village of Granite, Wyoming, belong to a sequence of isolated metavolcanic and metasedimentary masses in the Sherman Granite of the southern Laramie Mountains. Similar rocks lie to the west, in the Precambrian uplifts of the southern Medicine Bow Mountains and Sierra Madre. A major fault system, the Cheyenne belt, splits these two ranges into northern and southern domains, and may constitute a suture along which Early Proterozoic … more

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.

Whistle, a Nearly Dormant Geyser in Upper Geyser Basin, Yellowstone National Park, Wyoming: The First Geyser to be Studied by Research Drilling

Description: The following report follows the first research drilling study on a geyser. Whistle, a nearly dormant geyser in the upper geyser basin in Yellowstone National Park, Wyoming, has been proven to depend its water supply on deep overpressured water that's a far more extensive system than surface measurements can determine.
