The 2012 U.S. Forest Service Planning Rule defines Species of Conservation Concern (SCC) as “a species, other than federally recognized threatened, endangered, proposed, or candidate species, that is known to occur in the plan area and for which the regional forester has determined that the best available scientific information indicates substantial concern about the species' capability to persist over the long-term in the plan area” (36 CFR 219.9). This overview was developed to summarize information relating to this species’ consideration to be listed as a SCC on the Rio Grande National Forest, and to aid in the development of plan components and monitoring objectives. 3.

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

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. -

Hoyt, Ph. D. University of Northern Colorado Department of Earth Sciences (Earth & Atmospheric Sciences) 1970-2020 1 1956-1970s: THE FIRST YEARS, Tollefson the Magnificent The first tale I ever heard about how the Department of Earth Sciences started hearkens out of the mid-1950s. Oscar W. Tollefson, who had almost graduated from the Univ. of Colorado (Ph D in geology), found himself sitting next to Colorado State College (CSC) President Bill Ross on a commercial flight between Washington, D.C. and Denver. Tolley, as he was universally known in professional circles, was the loquacious sort and so of course he struck up a conversation with a guy who, it turns out, was an amateur rock , fossil, and mineral collector. Bill Ross came from a background in buildings and grounds and knew a lot about earth materials and weather! Though we don’t know exactly what was said in that four hours, we do know that Bill Ross recognized a rare enthusiasm for teaching and learning in the young Tolley. Ross also probably recognized that Tolley’s persuasiveness and persistence would go a long way at the growing College. The Earth Sciences academic program was founded at Colorado State College (CSC) in 1956 by Dr. -

The journal was patterned after the journal Radiocarbon and covered isotopic age-dating (except carbon-14) on rocks and minerals from the Western Hemisphere. Initially, the geographic scope of papers was restricted to the western half of the United States, but was later expanded. The journal was sponsored and staffed by the New Mexico Bureau of Mines (now Geology) & Mineral Resources and the Nevada Bureau of Mines & Geology.

Central Region Technical Attachment 93-01 the Front Range/Palmer
AMS-73-0P - 95B O l **-rTiT.i-tc~,rg-rT LIBRARY JUN 18 2010 f CRH SSD Atmospf- JANUARY 1993 CENTRAL REGION TECHNICAL ATTACHMENT 93-01 THE FRONT RANGE/PALMER DIVIDE BLIZZARD OF 7 JANUARY 1992 Ron McQueen and Ray Wolf National Weather Service Forecast Office Denver, Colorado 1. Introduction A moderate intensity blizzard struck the eastern edge of the Colorado Front Range and northeast Palmer Divide on 7 January 1992. The storm produced up to 22 inches of snow with three to six foot drifts (including 14 inches of snow in twenty-four hours at the Weather Service Forecast Office in Denver (WSFO DEN), a record for January). This was a result of a rapidly intensifying eastward moving cyclone. Blizzard conditions were most pro nounced in a 30 to 40 mile wide band, mainly east of Interstate 25 from the Wyoming border south to the Palmer Divide (Figure 1). This storm also caused heavy snow in the Four Corners area on the 6th, and the Colorado mountains on the 6th and 7th. Widespread heavy snow on the 6th amounted to between three and eight inches in the Four Corners. Two day snowfall totals for the mountains ranged from 12 to 18 inches in the Southwest Mountains and between 8 and 25 inches in the Northern and Central Mountains. This storm provided an excellent opportunity for forecasters at WSFO Denver to use the Denver AWIPS Risk Reduction and Re quirements Evaluation (DARE) workstation to its fullest diagnos tic and forecasting capacities. The DARE workstation is the functional prototype AWIPS workstation. -
