From abstract: The Legin group area comprises five privately owned claims, nine Government claims, and some public land. The area is in parts of secs. 28 and 29, T. 43 N., R. 19 W., New Mexico principal meridian, San Miguel County, Colo. It is about 45 miles from the Government mill at Monticello, Utah, and 50 miles from the Vanadium Corporation of America mill at Naturita, Colo. The Legin group area has yielded a total production of more than 18,000 short tons of carnotite ore that averaged 0.32 percent U30 and 2.5 percent V 205 . Most of this production was accomplished during the years from 1935 to 1944, and from 1949 to October 1951.

The following report covers a reconnaissance for new discoveries of radioactive lignite deposits in the Green River Basin and Uinta Basin of Wyoming and Utah where similar discoveries to previous studies in North Dakota, South Dakota, Montana, and Wyoming were made. Additionally, there were new prospects examined, as well as reconnaissance for uranium deposits.

Report discussing the reconnaissance for radioactive uraniferous rocks in parts of Colorado, Wyoming, and Utah. Regional geology of each area, results of regional reconnaissance, and miscellaneous prospects are included.

From Introduction: "The Leadville Quadrangle, Colorado (Fig. 1), was evaluated to identify and delineate areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits. Geologic environments were placed into one of three categories--favorable, unfavorable, or unevaluated--based on National Uranium Resource Evaluation (NURE) program."

Appendices containing supplementary analytical data of uranium occurrences, chemical analyses of stream-sediment, rock, and soil samples, and tabulated radiometric and gamma-ray anomaly data to accompany a report on U.S uranium resources in the Leadville Quadrangle, Colorado.

Abstract: Nine artificial-recharge pits were excavated in the alluvium in upper Black Squirrel Creek basin, Jimmy Campy Valley, and in the alluvium overlying the Widefield aquifer in Fountain Valley. Each artificial-recharge site was instrumented to measure inflow, stage fluctuations, and water-table fluctuations. Artificial-recharge tests conducted in upper Black Squirrel Creek basin indicated that the average adjusted rates of infiltration for the three sites ranged from 1.6 to 2.4 feet (0.5 to 0.7 meter) per day. Tests conducted in Jimmy Camp Valley indicated that the average adjusted rates of infiltration for the two sites ranged from 3.8 to 24.7 feet (1.2 to 7.5 meters) per day. Tests conducted on the Widefield aquifer indicated that the average adjusted rates of infiltration for four sites ranged from 2.3 to 12.9 feet (0.7 to 3.9 meters) per day.

Abstract: The Lake Minnequa area, located immediately south of the Arkansas River, is mantled with as much as 46 feet (14 meters) of alluvium covering bedrock of Pierre Shale and Niobrara Formation. Surface water enters the area by the Minnequa Canal and the St. Charles Flood Ditch. The water is stored in Lake Minnequa and other reservoirs. Seepage from St. Charles Reservoirs No. 2 and No. 3 is the major source of water to the alluvial aquifer. The depth of the water table ranges from 0 to 40 feet (0 to 12.2 meters). A 0.5-square-mile (1.3-square-kilometers) area immediately south of Lake Minnequa has a water table less than 6 feet (1.8 meters) below land surface. Lake Minnequa is the principal cause of the shallow water table and resulting waterlogged soil. The bedrock hill east of Lake Minnequa and ground-water flow also contribute to the problem. To eliminate the waterlogging problem, the water table would have to be at least 6 feet (1.8 meters) below land surface. Possible alternatives for eliminating the problem include lowering the water, level in Lake Minnequa, placing a network of dewaterinq wells, or constructing a drainage system in the waterlogged area.
