ISBN 1061-7930 SURVEY NOTES 1 Hal Morris, ''Utah Mapper'' by Fitz Davis uring his distinguished ca D reer with the U.S. Geological Survey (USGS), Hal T. Morris authored or co-authored 62 reports pertaining to the geology and miner al deposits in western Utah. Many of these reports contain excellent ge ologic maps, and some deal exclu sively with the geology of a particu lar area. Highlights of his published mapping include the Richfield and Delta 2° quadrangles, ten 7.5-minute quadrangles, and maps for Cove Fort, southern Pine Valley, Milford, and east half of the Frisco quadran gle. Hal also wrote a significant structural paper, "Interrelations of thrust and transcurrent faults in the central Sevier orogenic belt near Leamington, Utah." Hal will always be best known for his collaborations with Thomas S. Lovering in the geologic mapping, studies of hydrothermal alteration, studies of ore deposits, and the de Hal, 1949, a young geologist in the Thomas Range, Juab County, Utah. velopment of exploration techniques for blind-ore deposits in the East Tin tic mining district.
