Report discussing the U.S. Geological Survey's investigation of the Calamity group area and the carnotite deposits which are found in this area, often in sandstone.

A report regarding Caronotite Resources of the Calamity Group Area, In Mesa County, Colorado.

From abstract and summary: Long Park and vicinity is in T. 47 N., R. 17 W., Montrose County, Colo. The U. S. Geological Survey started a program of drilling in the area in April 1949, to find deposits that might be developed into new mines and to appraise the reserves of the area. This drilling was done during two periods of time under separate contracts.

Report discussing an investigation of copper deposits in sandstone that were believed to be possibly uraniferous, and uraniferous asphaltite deposits.

Report discussing different types of uranium deposits found in Colorado mines and the geological guides which can help locate these deposits.

"This paper summarizes the results of the field studies of the Survey's Reconnaissance Group and outlines some geologic criteria that may be useful in guiding the search for uranium ore. The writers wish to acknowledge the cooperation of the minding companies and individuals who materially aided the program of investigations by reporting radioactive localities and by submitting samples of radioactive rocks and ores."

Discussing a reconnaissance of uranium-bearing deposits in the Yampa River Region, in Colorado

Introduction: Studies of uranium-vanadium occurrences in the Four Corners region show that, with the exception of the Lukachuai area, all of the major deposits in the Morrison formation are grouped around the various igneous masses which are scattered irregularly throughout the Colorado Plateau. The pattern of deposition varies from mountain group to mountain group and each will be described separately. Maps accompany this report to supplement the descriptions of ore occurrences in the vicinity of the La Sal, Abajo, Carrizo, and Henry mountains. Elsewhere, it is believed that a written description will suffice.
