Tabulation or Ore Reserves and Past Production for the Uranium-Vanadium Region of Colorado, Utah, New Mexico, and Arizona

Description: The tabulations on these pages include all of the known areas in Colorado, Utah, New Mexico, and Arizona having economically important uranium-vanadium deposits of the type which are generally referred to by the terms roscoe-lite and/or carnotite. Though similar deposits are known to exist in other areas they are to be viewed as being little more than mineralogical curiosities.

Memorandum Listing the Areas in Colorado, Utah, Arizona and New Mexico that are Geologically Favorable for Developing Large Reserves of Vanadium Ore by Prospecting

Description: Introduction: Vanadium ore is being mined at many places in western Colorado, southeastern Utah, northeastern Arizona, and northwestern New Mexico (fig. 1). Eight mills in this region produced about 4,300,000 pounds of V2 05 in 1942, representing about 90 percent of the vanadium obtained from domestic sources. Although ore production has mostly exceeded mill capacity since 1937, production during the last half of 1942 averaged only about 19,000 tons or ore a month, whereas the capacity of these… more

Vanadium Deposits of Colorado and Utah: a Preliminary Report

Description: From abstract: Deposits of vanadium-bearing sandstone are widely distributed in western Colorado and eastern Utah and have been the principal domestic source of vanadium, uranium, and radium. Except during a few years when operations were relatively small, deposits at one or more places in this region have been intensively mined since 1909. Production has increased considerably each year since 1937.

Nickel Deposit Near Gold Hill, Boulder County, Colorado

Description: From Introduction: "Scattered throughout the Colorado Front Range, there are many small copper deposits, believed to be of pre-Cambrian age. The have been widely prospected but have produced little or no ore. In one of these, the Copper King mine, near Gold Hill, Colo., nickel was discovered in 1930, and development in the following years has exposed some 25,000 tons of ore containing from 2 to 3 percent of nickel. No other nickel deposit is known in the Front Range, but a somewhat similar depo… more

Stratigraphy, Structure, and Mineralization in the Beaver-Tarryall Area, Park County, Colorado: A Reconnaissance Report

Description: From Introduction: "The recent large increase in gold production from the Alma district has greatly stimulated interest in territory immediately to the east, where many small gold-bearing veins have been discovered. Consequently, as a cooperative project of the United States Geological Survey and the State of Colorado, 7 weeks in 1938 were devoted to renaissance work to determine the origin of the placer gold and the possibilities for discovering valuable lode deposits either near the surface o… more

Regrassing for Soil Protection in the Southwest

Description: "This bulletin is designed to help the stockmen and farmers, of the Southwest [United States] particularly, in reestablishing depleted ranges where unfavorable climatic conditions and heavy demands on the range have served to make improvement of the range by natural means a slow and difficult process. It discusses the latest methods of artificial revegetation that have proved most effective in regrassing the ranges. It also discusses the more promising grasses and indicates that areas to which … more

Strawberry Culture: Western United States

Description: Revised edition. "This bulletin applies both to the western portions of the United States in which ordinary farm crops are grown largely under irrigation and to western Oregon and Washington where irrigation is not essential for strawberry production but may be profitable. It describes methods practiced in the more important commercial strawberry-growing districts of the West; it aims to aid those persons familiar only with local and perhaps unsatisfactory methods, as well as inexperienced pros… more

Strawberry Culture: Western United States

Description: Revised edition. "Strawberries can be grown in those parts of the western Untied States in which ordinary farm crops are irrigated as well as in western Oregon and Washington, where irrigation is not essential but may be profitable. The principles of irrigating strawberries are essentially the same as those for other crops. Because strawberries are sensitive to the alkali salts that irrigation brings to the surface, such salts must be washed out or skimmed off. The strawberry grower, after choo… more
