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. -

final environmental statement wild and scenic river study september 1979 GUNNISON RIVER COLORADO SPECIAL NOTE This environmental statement was initiated by the Bureau of Outdoor Recreation (BOR) and the Colorado Department of Natural Resources in January, 1976. On January 30, 1978, a reorganization within the U.S. Department of the Interior resulted in BOR being restructured and renamed the Heritage Conservation and Recreation Service (HCRS). On March 27, 1978, study responsibility was transferred from HCRS to the National Park Service. The draft environmental statement was prepared by HCRS and cleared by the U.S. Department of the Interior prior to March 27, 1978. Final revisions and publication of both the draft environmental statement, as well as this document have been the responstbility of the National Park Service. FINAL ENVIRONMENTAL STATEMENT GUNNISON WILD AND SCENIC RIVER STUDY Prepared by United States Department of the Interior I National Park Service in cooperation with the Colorado Department of Natural Resources represented by the Water Conservation Board staff Director National Par!< Service SUMMARY ( ) Draft (X) Final Environmental Statement Department of the Interior, National Park Service 1. Type of action: ( ) Administrative (X) Legislative 2. Brief description of action: The Gunnison Wild and Scenic River Study recommends inclusion of a 26-mile (41.8-km) segment of the Gunnison River, Colorado, and 12,900 acres (S,200 ha) of adjacent land to be classified as wild in the National Wild and Scenic Rivers System under the administration of the National Park Service and the Bureau of Land Management, U.S. D. I. This river segment extends from the upstream boundary of the Black Canyon of the Gunnison National Monument to approximately 1 mile (1.6 km) below the confluence with the Smith Fork. -
Pleistocene Drainage Changes in Uncompahgre Plateau-Grand

C.; Callender, J. F.; [eds.], New Mexico Geological Society 32nd Annual Fall Field Conference Guidebook, 337 p. This is one of many related papers that were included in the 1981 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

DBS-61 posthunt population estimate 1987-2019. Background and Issue Summary: The Dolores River Desert Bighorn sheep herd (DBS-61) is located in southwest Colorado and occupies the canyon country of the Dolores River, and its tributaries, downstream of McPhee Reservoir. It consists of Game Management Units (GMUs) S-63 (Middle Dolores River) and S-64 (Upper Dolores River). The majority of the occupied bighorn habitat occurs on lands managed by the Bureau of Land Management (BLM). DBS-61 is a Tier 1 bighorn population and should be given the highest priority for inventory, habitat protection and improvement, disease prevention and research. Although bighorn sheep were likely indigenous, none were present in the past century. The current population was established beginning in 1986 with the release of 25 bighorn from Arizona. There have been a total of four transplants of desert bighorn into the Dolores Canyon. Population sources have been from Arizona (source for two transplants), Nevada, and Utah.
