Relation of Uranium to Hypogene Mineral Zoning in the Front Range Mineral Belt, Colorado
From abstract: Many of the mining districts of the Colorado Front Range mineral belt contain mesothermal sulfide ores that exhibit a zonal distribution. Present data indicate that in most of the zoned districts pitchblende and/or secondary uranium minerals are most abundant in a transition zone between central areas containing predominantly pyritic gold ores and peripheral areas containing dominantly lead-zinc-silver deposits. Copper in the form of chalcopyrite is also probably more abundant in the transition zone than in adjacent zones.

Mineral Resources of the Willow Creek and Skull Creek Wilderness Study Areas, Moffat County, Colorado
Abstract: The Willow Creek Wilderness Study Area (CO-010-002) and the Skull Creek Wilderness Study Area (C-010-003), which contain 13,368 acres and 13,739 acres, respectively, are in northwest Colorado near the Utah border. There are no identified resources in either of the study areas. The study areas have low resource potential for undiscovered uranium, vanadium, copper, and all other metals; oil and gas; and coal.

Treasure Hill Area, Larimer County, Colorado
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.

Geology of the Hot Sulphur Springs quadrangle, Grand County, Colorado
Scope and Purpose of Work: The quadrangle was mapped as part of the U.S. Geological Survey program of classifying and evaluating lands in the Public Domain. Mineral rights for coal had been retained in parts or all of Tps. 2 and 3 N., Rs. 77, 78, and 79 W. These areas are in part underlain by sedimentary rocks of Late Cretaceous(?) and early Tertiary age (Middle Park Formation), and in North Park these rocks are called the Coalmont Formation and contain coal. The chief purpose of the work was to map and study any coal beds found and to make a detailed geologic map that can be used as part of a geological atlas of the United States.
