Geologic Map of the Central San Juan Caldera Cluster, Southwestern Colorado by Peter W
Geologic Map of the Central San Juan Caldera Cluster, Southwestern Colorado By Peter W. Lipman Pamphlet to accompany Geologic Investigations Series I–2799 dacite Ceobolla Creek Tuff Nelson Mountain Tuff, rhyolite Rat Creek Tuff, dacite Cebolla Creek Tuff Rat Creek Tuff, rhyolite Wheeler Geologic Monument (Half Moon Pass quadrangle) provides exceptional exposures of three outflow tuff sheets erupted from the San Luis caldera complex. Lowest sheet is Rat Creek Tuff, which is nonwelded throughout but grades upward from light-tan rhyolite (~74% SiO2) into pale brown dacite (~66% SiO2) that contains sparse dark-brown andesitic scoria. Distinctive hornblende-rich middle Cebolla Creek Tuff contains basal surge beds, overlain by vitrophyre of uniform mafic dacite that becomes less welded upward. Uppermost Nelson Mountain Tuff consists of nonwelded to weakly welded, crystal-poor rhyolite, which grades upward to a densely welded caprock of crystal-rich dacite (~68% SiO2). White arrows show contacts between outflow units. 2006 U.S. Department of the Interior U.S. Geological Survey CONTENTS Geologic setting . 1 Volcanism . 1 Structure . 2 Methods of study . 3 Description of map units . 4 Surficial deposits . 4 Glacial deposits . 4 Postcaldera volcanic rocks . 4 Hinsdale Formation . 4 Los Pinos Formation . 5 Oligocene volcanic rocks . 5 Rocks of the Creede Caldera cycle . 5 Creede Formation . 5 Fisher Dacite . 5 Snowshoe Mountain Tuff . 6 Rocks of the San Luis caldera complex . 7 Rocks of the Nelson Mountain caldera cycle . 7 Rocks of the Cebolla Creek caldera cycle . 9 Rocks of the Rat Creek caldera cycle . 10 Lava flows premonitory(?) to San Luis caldera complex . .11 Rocks of the South River caldera cycle . -
GEOLOGY and OIL and GAS PROSPECTS of the HUNTLEY FIELD, Montanj
GEOLOGY AND OIL AND GAS PROSPECTS OF THE HUNTLEY FIELD, MONTANj By E. T. HANCOCK. INTRODUCTION. The Huntley field is in Yellowstone and Big Horn counties, south- central Montana, and embraces an area of about 650 square miles, part of which lies northwest and part southeast of Yellowstone River. The field has railroad facilities that are exceptionally good for this general region, being traversed by the main lines of the Northern Pacific and the Chicago, Burlington & Quincy railroads. These roads furnish excellent shipping facilities at Huntley, Warden, Ballantine, Pompeys Pillar, and other points. Acknowledgments. In presenting this report the writer desires to express his thanks to David White for valuable suggestions and criticisms, to T. W. Stanton and F. H. Knowlton for the identifica tion of fossils, and to C. E. Dobbins for assistance in the detailed mapping. He also wishes to call attention to the public service rendered by oil and gas operators who have furnished records of deep borings and by individuals who have contributed in various ways to the success of the investigation. Earlier investigations. The Huntley field is in reality an ex tension of the Lake Basin field, which was mapped by the writer during the summer of 1916.1 The geologic investigation of the region including the Lake Basin and Huntley fields began with the Northern Transcontinental Survey of 1882. Prior to that time geologists had described certain struc tural features and the stratigraphic succession at points closely ad jacent to these fields, such as Judith Gap, the canyon of the North Fork of the- Musselshell, and the Bridger Range, but almost noth ing had been written concerning the geology of the area herein de scribed. -

The Ranch is the largest remaining privately-held block of land in this pristine Rocky Mountain setting. Tucked against the famed Bridger Mountain Range, the Ranch possesses dramatic vistas of the Bridger Mountains and nearby Bangtail Range. It is a comfortable fifteen-minute drive on State Highway 86 (Bridger Canyon Road) to downtown Bozeman. The proximity of the Ranch to a commercial airport, private FBOs and interstate travel within a 25-minute drive make it readily accessible year-round. The secluded trout waters of Bridger Creek course through the core of the Ranch for nearly three miles. This quality alpine-fishing stream hosts healthy populations of brook and rainbow trout. The west side of the Ranch borders the Bridger Bowl Ski Resort and approximately three and a half miles of the Gallatin National Forest, providing unlimited hunting and recreational opportunities. The varied ecosystem of mountains, alpine meadows, and grassy creek bottoms offers prime habitat for an abundance of Rocky Mountain wildlife including elk, mule deer, whitetail deer, bear, mountain lion, moose, and upland game birds. -
Affected Bighorn Sheep Herds S-22 San Luis Peak Sub-Herd
On June 25th and 26th 2012, Seth Ratering USFS Range Tech, Doug Clark USFS Wildlife Tech, and Kevin Suellentrop USFS Wildlife Tech, inspected Table Mountain, Snow Mesa and the Ouray Sheep allotments. The intent of the visit was to locate bighorn sheep, collect bighorn scat, to get familiar with the allotments, and also to check on the ground conditions. No bighorn sheep were spotted during this visit although they are known to be present. We did collect one sample of possible bighorn sheep scat. Determining whether or not the scat was in fact bighorn sheep was difficult due to high population of elk and deer, who also had scattered scat in the whole area. The drought conditions are extremely evident around the whole area, especially above treeline where contact with moisture was limited. Bog sedge (Kobresia myosuroides) was extremely dry and showed very little recent production. It appears it produced early and was able to go to seed, but is now almost completely browned (photo 1). Various forbs are also very unproductive. The only available water on these high mesas is in the lakes and kettles and the few boggy areas (photo 2). During our visit, the mornings did not even produce dew on the vegetation. The east side of the Miners pasture will not be used this year. Instead, the Ouray allotment will be used in the beginning of the grazing season. This allotment has not been used for a number of seasons and shows signs of needing some disturbance. The amount of residual plant matter is beginning to hamper plant vigor in areas of high production. -
Spatial Variations in Snow Stability on Uniform Slopes
SPATIAL VARIATIONS IN SNOW STABILITY ON UNIFORM SLOPES: IMPLICATIONS FOR EXTRAPOLATION TO SURROUNDING TERRAIN by Christopher Cameron Landry A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Earth Sciences MONTANA STATE UNIVERSITY Bozeman, Montana April 2002 COPYRIGHT by Christopher Cameron Landry 2002 All Rights Reserved ERRATA The author, Christopher C. Landry, wishes to inform readers of the Master of Science thesis titled "Spatial variations in snow stability on uniform slopes: implications for extrapolation to surrounding terrain", published April 2002, of an error in the statistical analyses of project results. T-statistic tests were mistakenly performed at p < 0.10 rather than at p < 0.05. Nonetheless, re-performing the T-statistic analyses at p < 0.05 altered the results only marginally, and the conclusions of the research remain unchanged. Subsequent to the publication of the thesis, and the discovery of this error, a peer- reviewed article was submitted, using an alternative statistical approach, and published in Cold Regions Science and Technology. Readers of the original these are referred to the following article: Landry, C., K. Birkeland, K. Hansen, J. Borkowski, R. Brown and R. Aspinall. 2004. Variations in snow strength and stability on uniform slopes. Cold Regions Science & Technology, Vol. 39, p. 205-218. APPROVAL of a thesis submitted by Christopher Cameron Landry This thesis has been read by each member of the thesis committee and has been found to be satisfactory regarding content, English usage, format, citations, bibliographic style, and consistency, and is ready for submission to the College of Graduate Studies. -

A Comparison of Plant Communities and Substrates of Avalanche And
A comparison of plant communities and substrates of avalanche and non-avalanche areas in South-Central Montana by Sharon Thornberry Eversman A thesis submitted to the Graduate Faculty in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE in Botany Montana State University © Copyright by Sharon Thornberry Eversman (1968) Abstract: A study was conducted in the Bridger Bowl area in the Bridger Range in south-central Montana, U,S,A., to determine vegetation and soil features of an avalanche area and compare avalanche tracks with areas where no avalanches occurred, 2x5 dm plots and quarter methods were employed in obtaining quantitative data of plant communities. Surface soil analyses were made. Increment cores were obtained to determine ages of trees, and some trees were cut to determine patterns of tree ring growth, Abies lasiocama is the dominant tree taxon in all timbered areas above 7000 feet. Fseudotsuga menziesii occurs where there is no snow movement and is dominant on forested slopes below 7000 feet. Perennial forbs and grasses occur on all open slopes in communities that have no correlation with snow movement. Exposure, substrate, available moisture, and altitude affect local variations of the herbaceous communities, The topographic features, long-existing snow movement, and the present vegetation patterns have developed concomitantly. / 7 / A COMPARISON OF PLANT COMMUNITIES AND SUBSTRATES OF AVALANCHE AND NON-AVALANCHE AREAS IN SOUTH-CENTRAL MONTANA by SHARON THORNBERRY EVERSMAN A thesis submitted to the Graduate Faculty in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE in Botany Approvedi Head, Major Department MONTANA STATE UNIVERSITY Bozeman, Montana June, 1968 -Iii- .
