<br />')ar: Ii <br />~ u'~ <br /> <br />The geology was reviewed in the field, and the parts <br /> <br />. of the project area where detailed mapping by other members <br />of the Geological Survey had not been completed were mapped <br /> <br />by the writer. Field mapping was done on aerial photographs. <br /> <br />The base map was prepared by the Topographic Division of <br /> <br />the U.S. Geological Survey from Army Map Service maps. <br /> <br />Detailed stratigraphic sections were measured in the project <br /> <br />area, and outcrops in adjacent areas in Utah, New Mexico, <br /> <br />and Arizona were examined. Color terms used to describe <br /> <br />rocks are taken from the "Rock-Color Chart" of the National <br /> <br />Research Council, (Goddard and others, 1948). <br /> <br />Records of the wells and springs were obtained, where <br /> <br />possible, from the Bureau of Indian Affairs, ute Mountain <br /> <br />Tribal officials, and local drillers. The writer also had <br />tt access to the published and unpublished geologic and <br />hydrologic data of the Holbrook, Ariz., Salt Lake City, Utah, <br /> <br />and Denver, Colo., office of the Ground Water Branch of <br /> <br />the U.S. Geological Survey. Additional information on <br /> <br />the geology and hydrology, including electric, gamma-ray, <br /> <br />and neutron logs of oil and gas test wells, was examined. <br /> <br />. <br /> <br />.;? tJ <br />
