Thesis an Investigation Into Beaver-Induced Holocene
THESIS AN INVESTIGATION INTO BEAVER-INDUCED HOLOCENE SEDIMENTATION USING GROUND PENETRATING RADAR AND SEISMIC REFRACTION: BEAVER MEADOWS, ROCKY MOUNTAIN NATIONAL PARK, COLORADO Submitted by Natalie Kramer Department of Geosciences In partial fulfillment of the requirements For the degree of Master of Science Colorado State University Fort Collins, Colorado Summer 2011 Master's Committee: Advisor: Ellen Wohl Co-Advisor: Dennis Harry Paul Meiman Copyright by Natalie Kramer 2011 All Rights Reserved ABSTRACT AN INVESTIGATION INTO BEAVER-INDUCED HOLOCENE SEDIMENTATION USING GROUND PENETRATING RADAR AND SEISMIC REFRACTION: BEAVER MEADOWS, ROCKY MOUNTAIN NATIONAL PARK, COLORADO This study used ∼1 km of near-surface seismic refraction (SSR) data and ∼6 km of ground pene- trating radar (GPR) data to infer the impact of Holocene beaver activity on sediment aggradation in Beaver Meadows, Rocky Mountain National Park. GPR data were used to uniquely identify radar packages of genetically related strata corresponding to glacial, non-glacial, and beaver-induced sed- imentation. The radar package relating to glacial deposition was wedge-shaped and predominantly composed of a diffraction-rich, chaotic facie. The radar package relating to alluvium was draped over the glacial deposits and was characterized by multiple facies, but in general contained complex, slightly continuous reflectors interfingered with continuous, horizontal to subhorizontal reflectors. The radar package related to beaver-induced sedimentation was characterized by a laterally con- tinuous parallel facie, interpreted to be ponded sediment, that abruptly truncated into a zone of chaotic reflectors, interpreted to be a beaver dam. In order to determine the relative magnitude of post-glacial deposition, the bedrock contact was determined using seismic refraction, GPR, auger data, and previous seismic and drilling studies. -
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. -

State of the Park Report
National Park Service U.S. Department of the Interior State of the Park Report Rocky Mountain National Park Colorado December 2017 National Park Service. 2017. State of the Park Report for Rocky Mountain National Park. State of the Park Series No. 50. National Park Service, Washington, DC. On the cover: Hallett Peak reflected in Dream Lake. NPS Photo. Disclaimer. This State of the Park report summarizes the current condition of park resources, visitor experience, and park infrastructure as assessed by a combination of available factual information and the expert opinion and professional judgment of park staff and subject matter experts. The internet version of this report provides additional details and sources of information about the findings summarized in the report, including references, accounts on the origin and quality of the data, and the methods and analytic approaches used in data collection and assessments of condition. This report provides evaluations of status and trends based on interpretation by NPS scientists and managers of both quantitative and non-quantitative assessments and observations. Future condition ratings may differ from findings in this report as new data and knowledge become available. The park superintendent approved the publication of this report. Executive Summary The mission of the National Park Service is to preserve unimpaired the natural and cultural resources and values of national parks for the enjoyment, education, and inspiration of this and future generations. NPS Management Policies (2006) state that “The Service will also strive to ensure that park resources and values are passed on to future generations in a condition that is as good as, or better than, the conditions that exist today.” As part of the stewardship of national parks for the American people, the NPS has begun to develop State of the Park reports to assess the overall status and trends of each park’s resources. -
