Statement of Dan Gibbs Executive Director Colorado Department Of
Statement of Dan Gibbs Executive Director Colorado Department of Natural Resources Before The Subcommittee on National Parks, Forests, and Public Lands of The House Natural Resources Committee April 2, 2019 Chairwoman Haaland, Ranking Member Young, and Members of the Subcommittee: On behalf of Governor Polis and the State of Colorado, we appreciate the opportunity to provide testimony on the Colorado Outdoor Recreation and Economy Act (H.R. 823). We strongly support the CORE Act and hope Congress will move swiftly to enact it. Governor Polis would have liked to be here today with his former colleagues to express his strong support for this legislation. As you know, as a member of Congress, Governor Polis had sponsored the Continental Divide Recreation, Wilderness and Camp Hale Legacy Act, which has now been incorporated into the broader CORE Act. Introduction This legislation—the product of years of collaboration among elected officials, businesses, community members, and a myriad of other interested and affected stakeholders across Colorado—would protect some of the most beloved public lands in Colorado for their unsurpassed recreation, scenery, wildlife, watersheds, historic, and other unique values. As the Executive Director of the Colorado Department of Natural Resources, I support this bill because it will benefit our wildlife by protecting critical habitat and migration corridors; it will protect the outstanding recreational experiences that bring people from across Colorado—and the world—to these special places; it will help safeguard Colorado’s water resources by protecting key watersheds and all water rights; it strikes the right balance by protecting key public lands from development, while protecting all existing mineral rights and leaving other appropriate lands available for mining, oil, and gas development; and because it complements the values and opportunities associated with our state lands. -

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. -
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. -

ROCKY MOUNTAIN National Park CO LO 1^^.00 UNITED STATES RAILROAD ADMINISTRATION NATIONAL PARK. SERIES Copyright by WiswaU The Village of Estes Park nestles in a quiet little valley, surrounded by mountains Page two An Appreciation of Rocky Mountain National Park By ENOS A. MILLS, Author of "Wild Life on the Rockies," "The Rocky Mountain Wonderland," etc. Written Especially fer the United States Railroad Administration j]HE Rocky Mountain National Park is a marvelous grouping of gentle ness and grandeur; an eloquent, wordless hymn, sung in silent, poetic pictures; a wilderness mountain world of groves and grass plots, crags and canyons, rounded lakes with shadow-matted shores that rest in peace within the purple forest. There are wild flowers of every color, and many a silken meadow edged with ferns. Brokenness and beauty, terrace upon terrace, a magnificent hanging wild garden. Over these terraces waters rush and pour. From ice-sculptured, snow-piled peaks, young and eager streams leap in white cascades between crowding cliffs and pines. Through this wildness winds the trail, with its secrets of the centuries, where adventures come and go and where the magic camp fire blossoms in the night. In these primeval scenes the grizzly bear gives to the wilderness its master spell; the mountain ram poses on the cliff; the laughing, varied voice of the coyote echoes when the afterglow falls; the home-loving beaver builds his willow-fringed hut; the birds sing; the cheerful chipmunk frolics and never grows up; and here the world stays young. The Rocky Mountain National Park holds adventure for every visitor. -
