The Kaiparowits region, a geographic and geologic reconnaissance of parts of Utah and Arizona

Uranium resources of the Green River and Henry Mountains districts, Utah - a regional synthesis

“…In 1875 and 1876, Gilbert (1877) studied the Henry Mountains. During the period from 1915 through 1923, Gregory and Moore (1931) made intermittent geologic investigations in the western parts of the Henry Mountains district. In the summers of 1926 and 1927, McKnight made a thorough investigation of the area between the Green and Colorado Rivers (McKnight, 1940).…”

Distribution of elements in sedimentary rocks of the Colorado Plateau - a preliminary report

“…In the San Rafael Swell (Gilluly and Reeside, 1928) Valley area Baker and others, 1936) of southeastern Utah and northeastern Arizona, the Carmel consists of sandstone, shale, and mudstone; but in southwestern Utah (Gregory and Moore, 1931;Gregory, 1938Gregory, , 1950Gregory, , 1951 it is composed chiefly of fossiliferouslimestone. Sediments of the Carmel formation deposited on the Colorado Plateau are estimated to have totaled about 2,800 cubic miles.…”

“…The original thicknesses of the rocks are now confined chiefly to the basin areas of the plateau (McKee, 1951): the Uinta Basin and Piceance basin (Fisher, D. J., 1936;Walton, 1944;Kinney, 1955) in the northern and northeastern part of the Colorado Plateau, the San Juan basin (Reeside, 1924;Sears, 1934;Sears and others, 1941;Silver, 1951) in the southeastern part, and the Black Mesa basin (Gregory, 1917) in the southwestern part. Upper Cretaceous rocks are also exposed in the high plateaus of Utah (Spieker, 1931(Spieker, , 1946 that border the Colorado Plateau on the northwest and in the Zion and Bryce Canyon National Parks regions of southwestern Utah (Gregory and Moore, 1931;Gregory, 1950).…”

“…The Entrada in central and southwestern Utah (Gregory and Moore, 1931;Gregory, 1938Gregory, , 1950Gregory, , and 1951and Gilluly and Reeside, 1928) consists of an earthy sandstone and siltstone facies which becomes a clean fine-grained sandstone in Colorado, eastern Utah, northeastern Arizona, and northern New Mexico (Craig and others, 1955). In the vicinity of Moab, Utah, a thick sandstone unit that overlies the Entrada sandstone is known as the Moab tongue of the Entrada .…”

Geology of the Green River Desert-Cataract Canyon region, Emery, Wayne, and Garfield Counties, Utah

“…Between October 1929 and September 1930 the stream flow in the river below the mouth of the Green River ranged from a minimum of about 2,000 secondfeet in January to a maximum of about 47,000 second-feet during the spring runoff in June. 2 The river flows in a deep narrow canyon and has a steep gradient with numerous rapids; the altitude of the river surface decreases from 3,880 feet at the mouth of the Green River to 3,460 feet at the mouth of the Dirty Devil River, which is at the average rate of nearly 9 feet per mile for a distance of 49 y% miles. Although the river normally contains an abundant water supply, the confining canyon walls permit access to the river at very few localities.…”
