Reconnaissance of Red Rock District, Cove Mesa, and Kinusta (Tree) Mesa, Arizona

Abstract

Red Rock district, Cow mesa, and Kinusta Mesa lie in southern Carrizo Mountain region of Apache County, Arizona, 25 miles south or the Utah state line. The Bed Rock district lies along the Arizona New Mexico line, and the two mesas are approximately 15 miles to the west (Plate I) • All o£ these areas are within the boundaries of Navajo reservations in Arizona and New Mexico. Union Mines Development Corporation mapped the rims and contacts of these areas by plane table, prospected and sampled intensively, and also mapped most of the ore showings in detail in 1943 and 1944. Extensive use was made of its reports in the present reconnaissance. Presuming that the previous sampling was careful and reasonably representative, no samples were cut on Cove Mesa or Kinusta Mesa during the present study. Field work was performed between January 2 and 24, 1951, by J. King and R. F. Droullard. Elevations or contacts and rim elevations ere determined by barometric leveling. After convenient bench marks were established on the mesa top, the elevation of contacts, ore horizons, and rims were measured with frequent checks to the bench marks. Locations were determined on a stereoscopic pair or aerial photographs. These data were then transferred to the Union Mines maps, and the structure contours were drawn.
