MOUNT SOPRIS 12,965 Feet
Aspen Ranger District 806 West Hallam Aspen, CO 81611 (970) 925-3445 (970) 925-5277- Fax United States Department of Agriculture MOUNT SOPRIS 12,965 feet LENGTH: 6 miles from Dinkle Lake ELEVATION GAIN: 4,253 feet AVERAGE HIKING/CLIMBING TIME: USGS MAP(S): Sopris 10 hours RECOMMENDED SEASON(S): SKILL FACTOR: More difficult Late spring and summer ATTRACTIONS/CONSIDERATIONS: If you plan to climb Sopris, allow two days. The first day, hike to the lakes, set up camp in a designated site and explore, fish or just enjoy the scenery. On the second day, get up early and begin climbing to finish the hike before the aftenoon thunderstorms. ACCESS: Procees south on Hwy 133 for 1.4 miles to Prince Creek Road and take a left. The trailhead is approximately 8 miles up the road and just before the Dinkle Lake at the Thomas Lake Trailhead. The first three miles to Thomas Lakes is easy. NARRATIVE: The easiest route is up the east ridge. From the upper lake, walk to the base of the steep slope to the southeast of the lake. Ascend this slope on the new hiking trail to the ridge, and continue across the high, sparsely timbered slope to the southern ridge. Follow this ridge up the mountain. You will come upon one stretch of fairy steep, loose rock but should have no problem if you use care. Soon you will be on the main ridge to the summit. Enjoy your view! You may want to cross one half mile saddle to West Sopris, which is the same elevation as East Sopris, and offers a superb view of the Crystal River Valley and Avalanche Creek. -

How to Prepare for Traveling on I-70 in Glenwood Canyon (Spring 2021)
How to prepare for traveling on I-70 in Glenwood Canyon (Spring 2021) I-70 in Glenwood Canyon Motorists traveling on Interstate 70 should prepare for reduced speeds, slick roads and limited visibility in Glenwood Canyon, as well as other spring weather conditions that are common along the I-70 mountain corridor. If there is rain in the forecast, motorists should anticipate a possible safety closure of I-70, rest areas and the Glenwood Canyon bike path in the canyon. These safety closures are to protect the traveling public from the potential for debris flow, mudslides or rockfall. Construction impacts will be much lighter on I-70 in Glenwood Canyon compared to Summer 2020. To ensure safety, motorists should plan for occasional lane closures, obey reduced speeds and drive with caution. CDOT also urges travelers to stay focused on the road and avoid distracted driving. Please see below for information about the Glenwood Canyon rest areas and bike path. How to plan ahead Motorists planning to travel on I-70, visit rest areas or ride the bike path in Glenwood Canyon should pay close attention to weather forecasts. I f there is rain in the forecast, be prepared for a safety closure of I-70, rest areas and bike path. CDOT recommends that travelers have a back up plan in the event that closures are necessary. Please refer to w ww.cotrip.org for the latest road conditions and route options. More information is below for planning an alternate route. CDOT also recommends that travelers bring an emergency kit with water, snacks, a flashlight and a blanket, as mountain conditions often change suddenly. -

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 Tectonic Evolution of the Madrean Archipelago and Its Impact on the Geoecology of the Sky Islands
The Tectonic Evolution of the Madrean Archipelago and Its Impact on the Geoecology of the Sky Islands David Coblentz Earth and Environmental Sciences Division, Los Alamos National Laboratory, Los Alamos, NM Abstract—While the unique geographic location of the Sky Islands is well recognized as a primary factor for the elevated biodiversity of the region, its unique tectonic history is often overlooked. The mixing of tectonic environments is an important supplement to the mixing of flora and faunal regimes in contributing to the biodiversity of the Madrean Archipelago. The Sky Islands region is located near the actively deforming plate margin of the Western United States that has seen active and diverse tectonics spanning more than 300 million years, many aspects of which are preserved in the present-day geology. This tectonic history has played a fundamental role in the development and nature of the topography, bedrock geology, and soil distribution through the region that in turn are important factors for understanding the biodiversity. Consideration of the geologic and tectonic history of the Sky Islands also provides important insights into the “deep time” factors contributing to present-day biodiversity that fall outside the normal realm of human perception. in the North American Cordillera between the Sierra Madre Introduction Occidental and the Colorado Plateau – Southern Rocky The “Sky Island” region of the Madrean Archipelago (lo- Mountains (figure 1).

Controls on Geothermal Activity in the Sevier Thermal Belt, Southwestern
PROCEEDINGS, 44th Workshop on Geothermal Reservoir Engineering Stanford University, Stanford, California, February 11-13, 2019 SGP-TR-214 Controls of Geothermal Resources and Hydrothermal Activity in the Sevier Thermal Belt Based on Fluid Geochemistry Stuart F. Simmons1,2, Stefan Kirby3, Rick Allis3, Phil Wannamaker1 and Joe Moore1 1EGI, University of Utah, 423 Wakara Way, suite 300, Salt Lake City, UT 2Department of Chemical Engineering, University of Utah, 50 S. Central Campus Dr., Salt Lake City, UT 84112 3Utah Geological Survey, 1594 W. North Temple St., Salt Lake City, UT 84114 [email protected] Keywords: Sevier Thermal Belt, hydrothermal systems, heat flow, geochemistry, helium isotopes, stable isotopes. ABSTRACT The Sevier Thermal Belt, southwestern Utah, covers 20,000 km2, and it is located along the eastern edge of the Basin and Range, extending east into the transition zone of the Colorado Plateau. The belt encompasses the geothermal production fields at Cove Fort, Roosevelt Hot Springs, and Thermo, scattered hot spring activity, and the Covenant & Providence hydrocarbon fields. Regionally, it is characterized by elevated heat flow, modest seismicity, and Quaternary basalt-rhyolite magmatism. There are at least five large discrete domains (50 to >500 km2) with anomalous heat flow, including ones associated with Roosevelt Hot Springs, Cove Fort, Thermo and the Black Rock desert. Helium isotope data indicate connections to the upper mantle are developed over the region of strongest and most concentrated hydrothermal activity. By contrast, stable isotope data demonstrate that most of the convective heat transfer is associated with shallow to deep circulation of local meteoric water. Quartz-silica geothermometry suggests that convective heat transfer is compartmentalized by stratigraphic horizons and sub-vertical faults. -
Chapter 3 of the State Wildlife Action Plan
Colorado’s 2015 State Wildlife Action Plan Chapter 3: Habitats This chapter presents updated information on the distribution and condition of key habitats in Colorado. The habitat component of Colorado’s 2006 SWAP considered 41 land cover types from the Colorado GAP Analysis (Schrupp et al. 2000). Since then, the Southwest Regional GAP project (SWReGAP, USGS 2004) has produced updated land cover mapping using the U.S. National Vegetation Classification (NVC) names for terrestrial ecological systems. In the strictest sense, ecological systems are not equivalent to habitat types for wildlife. Ecological systems as defined in the NVC include both dynamic ecological processes and biogeophysical characteristics, in addition to the component species. However, the ecological systems as currently classified and mapped are closely aligned with the ways in which Colorado’s wildlife managers and conservation professionals think of, and manage for, habitats. Thus, for the purposes of the SWAP, references to the NVC systems should be interpreted as wildlife habitat in the general sense. Fifty-seven terrestrial ecological systems or altered land cover types mapped for SWReGAP have been categorized into 20 habitat types, and an additional nine aquatic habitats and seven “Other” habitat categories have been defined. SWAP habitat categories are listed in Table 4 (see Appendix C for the crosswalk of SWAP habitats with SWReGAP mapping units). Though nomenclature is slightly different in some cases, the revised habitat categories presented in this document -
