Abstract: The Treasure Hill area consists of eight mining-lode claims in secs. 10 and 15, T. 9 N., R. 70 W., Larimer County, Colo. All of the workings were examined and samples were taken from most of them. The results of the examination indicate that there is little or no detectable radioactivity in the schist and granite of the area.

Report documenting the suitability of Colorado for plant locations to produce synthetic liquid fuels, based on raw materials such as coal, oil shale, natural gas, and oil-impregnated strippable deposits.

Volume of supplementary data, illustrations, and other information related to a study of the suitability of areas in Colorado for developing coal, natural gas, oil shale, and other deposits into synthetic liquid fuels.

From introduction: The reconnaissance was made during the summer of 1951 by two field parties: (1) a reconnaissance in parts of Oklahoma, Texas, New Mexico, and Arizona by Russell Gibson, and (2) Geological Survey reconnaissance in parts of New Mexico,.Colorado, Utah, Idaho, and Wyoming (by the writers), the results of which are summarized in this report.

From abstract: An area 2,200 feet long and 400 to 1,300 feet wide within the Haputa ranch, Custer County, Colo., has been mapped at a scale 1:1,200. The rocks in this area consist of quartz-hornblende schist, granite gneiss, hornblende-andesine gneiss, gabbro and peridotite, microcline granite, and pegmatite, of pre-Cambrian age, and lamprophyre dikes of Tertiary age.

A letter written to T. N. Carswell from Ruby Conaway McIntosh, Denver, Colorado. McIntosh advises Carswell that she read of his work in the Abilene Reporter and has enclosed a clipping about a friend doing similar rehabilitation for the state of Colorado. The enclosure includes an article printed by the Denver Post dated October 29, 1951 titled "Let Your Heart Fill Your Chest -- Parolees Get Help."

"This report describes the geologic and hydrologic characteristics of the ore-bearing sandstone as determined in the core samples from three diamond drill holes on calamity Mesa, Mesa County, Colorado, and correlates these data with localized gamma-ray activity detected in three drill holes."

From introduction: The results of U. S. Geological Survey exploration in the Legin group area are summarized briefly in this preliminary report. No additional drilling is planned. The Legin group area comprising nine Government-owned claims, three privately owned claims and adjoining public land, is in San Miguel County, Colo. The area explored includes parts of secs. 28 and 29, T. 43 N., R. 19 W., New Mexico principal meridian (fig. 1).

Report discussing "field and laboratory studies of ground-water conditions in the carnotite-bearing Morrison formation in southwestern Colorado and southeastern Utah" with the objective of determining "possible relations between ground waters and the carnotite deposits."

Report summarizing the study of carnotite-bearing sandstone deposits in the Colorado Plateau.

Abstract: Results of detailed mapping of the Salt Wash sandstone member of the Morrison formation in the Uravan and Gateway districts, Montrose and Mesa Counties, Colo., suggest that large areas containing both lenticular bedding in the ore-bearing sandstone and persistently altered mudstone beneath the sandstone are generally favorable for carnotite deposits.

From introduction: Mapping, sampling, and radiometric reconnaissance of the uranium-bearing deposits in the Laramie formation in the vicinity of the Old Leyden coal mine, sec. 28, T. 2 S., R. 71 W., Jefferson County, Colorado (fig. 1), was completed August 10, 1951. Topographic and geologic maps were made of areas approximately 6,000 feet by 3,000 feet (scale 1:2h00), and 1,200 feet by 800 feet (scale 1:600). Underground workings at three clay mines and at the Old Leyden mine were also mapped. With the exception of the 1:600 map, which accompanies this report, these maps will be transmitted later with a more comprehensive report.
