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. -

Impact Report Photo by Riley De Ryk Letter from the Director
Rocky Mountain Field Institute 2020 Community Impact report Photo by Riley de Ryk Letter FROM The Director Dear Friends and Supporters of RMFI, It goes without saying that 2020 was a year like no other. Yet, despite all of the challenges we, and the rest of the world, had to overcome, we, above all else, remained grateful. Grateful that we were still able to operate; grateful that we were able to employ nearly 30 people and do so safely; grateful that so many sought and relied on nature for mental, physical, and emotional well-being; and grateful that we accomplished incredibly impactful stewardship projects at a time when our public lands needed them most. We could not have accomplished all that we did without your generosity, support, and steadfast commitment to RMFI. We sincerely appreciate each and every one of you who collectively make the work that we do possible. Thank you. When the pandemic hit in March 2020, we were faced with tremendous uncertainty as to whether we’d even be able to have a field season. But, the more we spoke with our key land management partners, the more it became clear they needed our staff and our expertise out on the ground. We immediately set out to develop COVID-19 operating procedures and guidelines to keep our staff and community safe and then got to work. Slowly, we began introducing volunteer opportunities into our schedule and when it was all said and done, we ended up having the biggest and most impactful season to date. Some important project highlights and accomplishments include finishing a new -

5B Part Two- MAY
Pike National Historic Trail Association Newsletter May-B 2016 Vol. 10 No. 5B Part Two- MAY Celebrating 210 Years- The Santa Fe Trail Association (SFTA) celebrated the Bicentennial of Pike’s 1806-7 Southwest Expedition 10 years ago. One can use our website- zebulonpike.org to recall the many activities conducted during 2006. The Pike National Historic Trail Association became the child of the SFTA. It was formed by John Patrick Michael Murphy and our current President. SFTA donated its website and many of its leaders including Dr. Leo Oliva and Dr. Clive Siegle volunteered. Others from the Bicentennial Committee quickly joined the effort including Zebulon Montgomery Pike, Dorothy Urban, and Mike Bandera with Dr. Rev. Roy Escott Pike, Erwin Young, Patrick Surrena, Tom Rollings and Rex Rideout. Bicentennial Liberty Bell & Daffodil Pike’s Damn’d Rascals- 4 John Brown BOTH expeditions. Went with Pike, Robinson and Miller to climb Pikes Peak Tried for desertion August 2, 1809, at New Orleans. He had deserted Lt. Wilkinson at Fort Adams November 21, 1807, and had been absent until June 6, 1809, when he surrendered to Maj. Amos Stoddard at Natchitoches. His sentence of corporal punishment was remitted because of voluntary surrender. Brown lived in the Cold Water district of St. Louis County, Missouri, for 42 years. When he died at the age of 86 his obituary appeared in the Missouri Republican, August 21, 1840. He is believed to be the oldest rascal. January 24, 1807 Saturday- Pikes Journal … he [Brown] exclaimed, “that it was more than human nature could bear, to march three days without sustenance, through snows three feet deep, and carry burdens only fit for horses” &c.&c.” “Brown, you this day presumed to make use of language which was seditious and mutinous, … I will pardon, but be assured, should it ever be repeated, by instant death, I will revenge your ingratitude and punish your disobedience.” This was one of a very few instances where Pike had to discipline. -

Wild Connections Conservation Plan for the Pike & San Isabel National Forests Chapter 5 – Complexes: Area-Specific Management Recommendations This section contains our detailed, area-specific proposal utilizing the theme based approach to land management. As an organizational tool, this proposal divides the Pike-San Isabel National Forest into eleven separate Complexes, based on geo-physical characteristics of the land such as mountain ranges, parklands, or canyon systems. Each complex narrative provides details and justifications for our management recommendations for specific areas. In order to emphasize the larger landscape and connectivity of these lands with the ecoregion, commentary on relationships to adjacent non-Forest lands are also included. Evaluations of ecological value across public and private lands are used throughout this chapter. The Colorado Natural Heritage Programs rates the biodiversity of Potential Conservation Areas (PCAs) as General Biodiversity, Moderate, High, Very High, and Outranking Significance. The Nature Conservancy assesses the conservation value of its Conservation Blueprint areas as Low, Moderately Low, Moderate, Moderately High and High. The Southern Rockies Ecosystem Project's Wildlands Network Vision recommends land use designations of Core Wilderness, Core Agency, Low and Moderate Compatible Use, and Wildlife Linkages. Detailed explanations are available from the respective organizations. Complexes – Summary List by Watershed Table 5.1: Summary of WCCP Complexes Watershed Complex Ranger District -

Photo credit Dean Waits. and Sam Laird, Bobbi Leavens and Charlie the Pooch. Photo credit Dean For April the snow was still a few feet deep near Tennessee Pass Waits. as it covered all but the top of one of the several remaining Coke PPG 100th Anniversary Hike to Barr Camp ovens. Yes, it’s been a great snow year for the Sawatch and Mosquito Ranges as explained by Eric Hunter, leader of these adventurous Pikes Peak Group trekkers. It was still cool and the snow relatively firm on this beautiful blue bird sky day, later warming into the 50’s thus softening the snow for this 8-mile jaunt and creating an anticipation for the cold beer and food later. The trail we hiked along is loaded with history and lots of current- day activity. In the 1880’s the Denver, Rio Grande & Western trains chugged along this roadbed to get over the pass and later through a tunnel. -
Contributions to the Geography of the United States, 1922
CONTRIBUTIONS TO THE GEOGRAPHY OF THE UNITED STATES, 1922. PENEPLAINS OF4 THE FRONT RANGE AND ROCKY MOUNTAIN NATIONAL PARK, COLORADO. By Wnxis T. LEE. PURPOSE OF THE PAPER. The purpose of this paper is to call attention to some of the major surface features in the Rocky Mountain National Park and to point out their probable correlation with similar features in neigh boring regions. The observations on which the paper is based were made in the summer of 1916, during an investigation in which other work demanded first consideration. This paper may therefore be considered a by-product. For the same reason many of the observa tions were not followed to conclusions, yet the data obtained seem to be sufficient to establish a certain order of events, the recognition of which may be of assistance in working out in detail the geologic and geographic history of the Rocky Mountain region. TWO CYCLES OF EROSION PREVIOUSLY RECOGNIZED. In an account of the general geology of the Georgetown quad rangle, Colo.j Ball x describes three distinct types of land forms " an old, mature mountainous upland; younger V-shaped valleys in cised in this upland; and glacial cirques developed at the heads of some of the streams, passing downward into U-shaped valleys." Ball describes the mountainous upland as consisting of highlands of rounded or gently sloping tops which are remnants of an ancient peneplain or old surface of erosion. Most of these remnants in the Georgetown quadrangle lie above an altitude of 11,500 feet. On thig old peneplain there were many monadnocks, some of which are now recognizable as the summits of the highest mountains. -
