Memorial to Quentin Dreyer Singewald 1902-1987 WALLACE D Memorial to Quentin Dreyer Singewald 1902-1987 WALLACE D. AND DOROTHEA WYCKOFF LOWRY 607 Rose Avenue, Blacksburg, Virginia 24060 When the Geological Society of America wrote asking us if we would prepare a memorial to Quentin Singewald, we were delighted, for he was a very special person to us ever since our college days in the late thirties and early forties. As his many friends knew, he was the younger brother of Joseph T. Singewald, professor of economic geology at Johns Hopkins University for many years. Quentin was bom in Baltimore on September 28, 1902. He received his B.S. in geology from Johns Hopkins in 1922 and his Ph.D. from that institution in 1926. Prior to receiving the doctorate, he worked summers (1921-1923) for the U.S. Geological Survey doing reconnaissance geologic mapping of petroleum and coal areas in the Rocky Mountains, studying the Cretaceous-Eocene contact in New Mexico, Colorado, and Wyoming, and mapping in the Tonopah quadrangle, Nevada. Upon completing his graduate studies he participated in the Johns Hopkins Ellsworth Expedition, which first mapped ore deposits in the headwaters of the Amazon River in Brazil and Peru. His work involved the preparation of a detailed cross section of the Andes of central Peru. Independently he made a petrographic study of igneous rocks from that area for inclusion in the Ellsworth report. Following work as a geologist with the Trans Continental Petroleum Company of Mexico in 1926-1927, he joined the faculty of the Colorado School of Mines as an assistant professor. In 1929 he left to join the faculty of the Department of Geology at the University of Rochester. In 1931 he was elected a Fellow of the Geological Society of America; B. S. Butler, Edward W. Berry, and Harold L. Ailing were his sponsors. In 1942 he left the University of Rochester and began a career of dedicated and distinguished service with the U.S. Geological Survey that would span more than 30 years. In the period 1942 to 1946 he led a mission to Colombia to assess its mineral resources. The mission’s work also included special short-term studies of mineral deposits in Bolivia and Venezuela. In the spring of 1946, he was assigned by the U.S. Geological Survey to the General Headquarters of the Supreme Commander for the Allied Powers in Tokyo, as chief of the Mining and Geology Division, Natural Resources Section. The Mining and Geology Division was staffed almost entirely by USGS geologists assigned to General Headquarters by the Military Geology Branch. The division’s function was to assess the mineral resources of Japan and to help get the Japanese mineral industry on its feet. While in Tokyo he met his future wife, Mary Boardman, who, as a former WAC with the Signal Corps, had been assigned to General MacArthur’s headquarters. Quentin and Mary were married June 28,1952, and as Sam H. Patterson, a former associate of Quentin Singewald, wrote recently, “Quentin and Mary were great people, and it is a darn shame they didn’t get together and tie the knot 25 years sooner.” In 1948, Quentin became the assistant branch chief of the USGS Mineral Deposits Branch and served in that capacity until 1952, when as regional geologist, he was made supervisor of the newly established Northeast District Office of the Mineral Deposits Branch, with headquarters in Beltsville, Maryland. In 1955 the southeastern U.S. area was added to his responsibilities. 103 104 THE GEOLOGICAL SOCIETY OF AMERICA In 1960-1962, Quentin was technical advisor to the International Cooperation Administration and served as professor and advisor in the Institute of Applied Geology at the University of Istanbul, Turkey. While he was there, an uprising took place; bullets broke windows in the room on campus where he was lecturing. While in Istanbul, Quentin and Mary enjoyed the privileges of the American officers* club, and it is said that Quentin became a fan of belly dancing. Upon their return to the United States, Quentin went to work as a research geologist based at the USGS Beltsville office. He retired in 1974 when the Survey’s new headquarters were established in Reston, Virginia. However, he continued to work on his Colorado studies at home. Allen Heyl, one of Quentin’s Survey associates, thinks highly of the study by Quentin and B. S. Butler of mineral deposits in the Mosquito Range near Alma, Colorado, published as Bulletin 911 of the USGS in 1941. Also according to Heyl, the geologic map of the Mount Tyndall quadrangle, Custer County, Colorado, by Quentin and Maurice R. Brock, is one of the most detailed maps ever published by the Survey. Many of Quentin’s Survey friends recall his supervision of the mapping of thorium deposits in the Wet Mountains of Colorado. That study was begun in the early fifties when thorium was considered a possibly important source of nuclear fuel. While in charge of the Beltsville office, he and Mary entertained that group at Christmas parties at their home in Silver Spring, Maryland. It is said everyone had a good time; as Allen Heyl reported, “Mary was a great cook; Quentin was a great host.” After retiring, Quentin donated his professional library, which included his brother’s complete sets of Economic Geology and the Bulletin of GSA and AAPG, to Ricker College in Maine. That college declared a Quentin Singewald Day in recognition of his contribution, and he and Mary were feted that day. Besides being a Fellow of GSA, Quentin was a member of the Society of Economic Geologists, American Association of Petroleum Geologists, Mineralogical Society of America, American Institute of Mining and Metallurgical Engineers, American Association for the Advancement of Science, Geological Society of Washington, and the Hopkins Club. Mary Singewald died of cancer in August 1984. Quentin died unexpectedly August 1,1987, in Florida where he and Mary had a winter home. As his friend Henry Bell of the Survey wrote, “Quentin was a kind and gentle man, and I have fond memories of him.” We certainly do, and we are sure he and Mary are missed by many others.

  • Aerial Survey Highlights for Colorado 2014
    Aerial Survey Highlights for Colorado 2014 Aerial detection surveys of tree killing or damaging insects and diseases are conducted annually over Colorado’s forest lands. This is a cooperative effort between the US Forest Service and the Colorado State Forest Service. In 2014, 28 million acres were surveyed by 7 trained federal and state surveyors. Highlights of the survey by damage agent are reported below. In 2014, all reported agents are insects that kill and/or defoliate trees. This report includes only forest damage that is visible from the air. Spruce Beetle • Since 1996, spruce beetle has affected approximately 1,397,000 acres to varying degrees in Colorado. • Spruce beetle activity was detected on 485,000 acres in Colorado in 2014. Of these, 253,000 acres are in areas not previously mapped as having spruce beetle activity (new acres). This epidemic continues to expand rapidly (Figures 1, 2). In some areas, the outbreak has moved through entire drainages in the course of one year. In the most heavily impacted drainages, nearly every mature spruce has been killed (Figure 3). • The spruce beetle epidemic is expanding most rapidly in southern Colorado’s Forests and impacts many thousands of acres. Areas affected are found from the La Garita Wilderness Area to north of Cottonwood Pass, the Sangre de Cristo and Wet Mountains, as well as south to the Colorado border and into New Mexico. Aerial survey in south central Colorado showed spruce beetle epidemics expanded on the San Juan (26,000 new acres on 53,000 active acres), Rio Grande (78,000 new acres on 192,000 active acres), Gunnison (54,000 new acres on 79,000 active acres), and San Isabel (26,000 new acres on 31,000 active acres) National Forests.

Mt. Olympus, mythological home of the Greek gods, Yosemite’s Half Dome, the ever-classic Matterhorn, Alaska’s Denali, and Colorado’s Pikes Peak all share the quality of compelling attraction that a charismatic alpine profile evokes. At the base of our peak along the confluence of two small, nondescript streams, Native Americans gathered thousands of years ago. Explorers, immigrants, city-visionaries and fortune-seekers arrived successively, all shaping in turn the region and communities that today spread from the flanks of Pikes Peak. From any vantage point along the Interstate 25 corridor, the Colorado plains, or the Arkansas River Valley escarpments, Pikes Peak looms as the dominant feature of a diverse “bioregion”, a geographical area with a distinct flora and fauna, that stretches from alpine tundra to desert grasslands. “Biodiversity” is shorthand for biological diversity: a term covering a broad array of contexts from the genetics of individual organisms to ecosystem interactions. The news tells us daily of ongoing threats from the loss of biodiversity on global and regional levels as humans extend their influence across the face of the earth and into its sustaining processes. On a regional level, biologists look for measures of biodiversity, celebrate when they find sites where those measures are high and mourn when they diminish; conservation organizations and in some cases, legal statutes, try to protect biodiversity, and communities often struggle to balance human needs for social infrastructure with desirable elements of the natural landscape.

  • Denudation History and Internal Structure of the Front Range and Wet Mountains, Colorado, Based on Apatite-Fission-Track Thermoc
    NEW MEXICO BUREAU OF GEOLOGY & MINERAL RESOURCES, BULLETIN 160, 2004 41 Denudation history and internal structure of the Front Range and Wet Mountains, Colorado, based on apatite­fission­track thermochronology 1 2 1Department of Earth and Environmental Science, New Mexico Institute of Mining and Technology, Socorro, NM 87801Shari A. Kelley and Charles E. Chapin 2New Mexico Bureau of Geology and Mineral Resources, New Mexico Institute of Mining and Technology, Socorro, NM 87801 Abstract An apatite fission­track (AFT) partial annealing zone (PAZ) that developed during Late Cretaceous time provides a structural datum for addressing questions concerning the timing and magnitude of denudation, as well as the structural style of Laramide deformation, in the Front Range and Wet Mountains of Colorado. AFT cooling ages are also used to estimate the magnitude and sense of dis­ placement across faults and to differentiate between exhumation and fault­generated topography. AFT ages at low elevationX along the eastern margin of the southern Front Range between Golden and Colorado Springs are from 100 to 270 Ma, and the mean track lengths are short (10–12.5 µm). Old AFT ages (> 100 Ma) are also found along the western margin of the Front Range along the Elkhorn thrust fault. In contrast AFT ages of 45–75 Ma and relatively long mean track lengths (12.5–14 µm) are common in the interior of the range. The AFT ages generally decrease across northwest­trending faults toward the center of the range. The base of a fossil PAZ, which separates AFT cooling ages of 45– 70 Ma at low elevations from AFT ages > 100 Ma at higher elevations, is exposed on the south side of Pikes Peak, on Mt.

The projects, both conducted by the Colorado Natural Heritage Program, are two distinct projects that are highly integrated with respect to methodology and fieldwork. Both projects utilized the same Natural Heritage methodology that is used throughout the globe, and both searched for and assessed the plants, animals, and plant communities on the Colorado Natural Heritage Program’s list of rare and imperiled elements of biodiversity. Each report prioritizes potential conservation areas based on the relative significance of the biodiversity they support and the urgency for protection of the site. All information explaining Natural Heritage methodology and ranks is repeated in each report, so that each report can stand alone and be used independently of the other. This report, Survey of Critical Biological Resources of Pueblo County, presents all potential conservation areas identified in Pueblo County that support rare and imperiled plants, animals, and significant plant communities, including wetland and riparian areas.
