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.

From July to August 1942, Hal worked at his first professional job as a geologist with the Utah Construction and Mining Company, then from August to Oc­ tober as a mineralogist with the U.S. Bureau of Mines in Salt Lake City. That year he also married Elizabeth Jones in Ogden, Utah. One month later, Hal was inducted into the less persnickety U.S. Army, where he served for three years in the Chemi­ cal Warfare Service. He served his final months in the army service on the island of Saipan. Upon his re­ turn to Ogden, Hal was greeted not Hal examining the first ore cut in the Burgin mine in 1957.
