Most of the glaciers Historical Perspective were valley glaciers, but ice caps formed on uplands Following early recognition of deposits of two alpine locally. Discussion of the deposits of all of these ranges glaciations (Gilbert, 1890; Ball, 1908; Capps, 1909; would require monographic analysis. To avoid this, Atwood, 1909), deposits of three glaciations gradually representative ranges in each province are reviewed. became widely recognized (Alden, 1912, 1932, 1953; Atwood and Mather, 1912, 1932; Alden and Stebinger, Purpose and Scope 1913; Blackwelder, 1915; Atwood, 1915; Fryxell, 1930; This report summarizes the evidence for correlation Bradley, 1936).

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. -

Principles and practices for the restoration of ponderosa pine and dry mixed-conifer forests of the Colorado Front Range. RMRS-GTR-373. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 121 p. Abstract Wildfires have become larger and more severe over the past several decades on Colorado’s Front Range, catalyzing greater investments in forest management intended to mitigate wildfire risks.The complex ecological, social, and political context of the Front Range, however, makes forest management challenging, especially where multiple management goals including forest restoration exist. In this report, we present a science-based framework for managers to develop place-based approaches to forest restoration of Front Range ponderosa pine and dry mixed-conifer forests. We first present ecological information describing how Front Range forest structure and composition are shaped at multiple scales by interactions among topography, natural disturbances such as fire, and forest developmental processes. -
5-Year Review Short Form Summary
5-Year Review Short Form Summary Species Reviewed: Preble’s meadow jumping mouse (Zapus hudsonius preblei) FR Notice Announcing Initiation of This Review: March 31, 2004. 90-Day Finding for a Petition to Delist the Preble’s Meadow Jumping Mouse in Colorado and Wyoming and Initiation of a 5-Year Review (69 FR 16944-16946). Lead Region/Field Office: Region 6, Seth Willey, Recovery Coordinator, 303-236-4257. Colorado Field Office, Susan Linner, Field Supervisor, 303-236-4773. Name of Reviewer: Peter Plage, Colorado Field Office, 303-236-4750. Cooperating Field Office: Wyoming Field Office, Brian Kelly, Field Supervisor, 307-772-2374. Current Classification: Threatened rangewide. Current Recovery Priority Number: 9c. This recovery priority number is indicative of a subspecies facing a moderate degree of threat, a high recovery potential, and whose recovery may be in conflict with construction or other development projects or other forms of economic activity. Methodology used to complete the review: The 5-year review for the Preble’s meadow jumping mouse (Preble’s) was accomplished through the petition and rulemaking process. On December 23, 2003, we received two nearly identical petitions from the State of Wyoming’s Office of the Governor and from Coloradans for Water Conservation and Development, seeking to remove the Preble’s from the Federal List of Endangered and Threatened Wildlife. Both petitions were similar and maintained that the Preble’s should be delisted based on the taxonomic revision, and based on new distribution, abundance, and trends data that suggested the Preble’s was no longer threatened. On March 31, 2004, we published a notice announcing a 90-day finding that the petitions presented substantial information indicating that the petitioned action may be warranted and initiated a 5-year review (69 FR 16944-16946). -
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. -

COLORADO CONTINENTAL DIVIDE TRAIL COALITION VISIT COLORADO! Day & Overnight Hikes on the Continental Divide Trail
CONTINENTAL DIVIDE NATIONAL SCENIC TRAIL DAY & OVERNIGHT HIKES: COLORADO CONTINENTAL DIVIDE TRAIL COALITION VISIT COLORADO! Day & Overnight Hikes on the Continental Divide Trail THE CENTENNIAL STATE The Colorado Rockies are the quintessential CDT experience! The CDT traverses 800 miles of these majestic and challenging peaks dotted with abandoned homesteads and ghost towns, and crosses the ancestral lands of the Ute, Eastern Shoshone, and Cheyenne peoples. The CDT winds through some of Colorado’s most incredible landscapes: the spectacular alpine tundra of the South San Juan, Weminuche, and La Garita Wildernesses where the CDT remains at or above 11,000 feet for nearly 70 miles; remnants of the late 1800’s ghost town of Hancock that served the Alpine Tunnel; the awe-inspiring Collegiate Peaks near Leadville, the highest incorporated city in America; geologic oddities like The Window, Knife Edge, and Devil’s Thumb; the towering 14,270 foot Grays Peak – the highest point on the CDT; Rocky Mountain National Park with its rugged snow-capped skyline; the remote Never Summer Wilderness; and the broad valleys and numerous glacial lakes and cirques of the Mount Zirkel Wilderness. You might also encounter moose, mountain goats, bighorn sheep, marmots, and pika on the CDT in Colorado. In this guide, you’ll find Colorado’s best day and overnight hikes on the CDT, organized south to north. ELEVATION: The average elevation of the CDT in Colorado is 10,978 ft, and all of the hikes listed in this guide begin at elevations above 8,000 ft. Remember to bring plenty of water, sun protection, and extra food, and know that a hike at elevation will likely be more challenging than the same distance hike at sea level. -
