New Mexico Geological Society Downloaded from: http://nmgs.nmt.edu/publications/guidebooks/19 Multiple intrusions in the San Miguel Mountains, Colorado Calvin S. Bromfield and Alfred L. Bush, 1968, pp. 94-99 in: San Juan, San Miguel, La Plata Region (New Mexico and Colorado), Shomaker, J. W.; [ed.], New Mexico Geological Society 19th Annual Fall Field Conference Guidebook, 212 p. This is one of many related papers that were included in the 1968 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

The mean temperature depression thus determined is ~8.6 +0.7/−0.9 ◦C where the uncertainties account for those inherent in the glacier reconstructions, in model parameters (e.g., melt factors), and possible modest changes in LGM precipitation. Associated equilibrium-line altitudes (ELAs) exhibit a statistically significant directional dependency being lower toward the north and east. Under the assumption that regional temperature change was uniform, required changes in precipitation vary systematically—also exhibit- ing a directional dependency coinciding with that in ELAs—and indicate increases (over modern) occurred on the eastern side of the massif while decreases occurred on the western side. This disparity represents a strengthening of a precipitation asymmetry, particularly winter precipitation, which Citation: Brugger, K.A.; Leonard, E.M.; Refsnider, K.A.; Dolan, P. -

GIS and Geostatistical Analysis of the La Plata Mining District
GIS and Geostatistical Analysis of the La Plata Mining District David S. Schiowitz1, W. Scott White2, and Jeffrey A. Cary3 1GIS/CAD Specialist Bikis Water Consultants, LLC 555 RiverGate Lane, Suite B4-82 Durango, CO 81301 970-385-2340 [email protected] 2Associate Professor Department of Geosciences – Fort Lewis College 1000 Rim Drive Durango, CO 81301 970-247-7475 [email protected] 3Visiting Instructor Department of Geosciences – Fort Lewis College 1000 Rim Drive Durango, CO 81301 970-247-7620 [email protected] ABSTRACT The La Plata mining district is located in southwestern Colorado, and contains numerous gold, silver, and copper deposits. Geologic and structural data for the district was obtained from georeferencing and digitizing an historic geologic map. New stream sediment samples were collected at 41 locations throughout the area, and analyzed for metal concentrations. Using ArcGIS’s surface hydrologic modeling tools, individual watersheds were delineated upstream for each sediment sample location. A geodatabase has been created consisting of geologic formations and structures, veins, rock ages, historic mines, and geochemical anomalies associated with the 41 watersheds. The Spatial Analyst extension was used to analyze the data to aid in visualization and quantification of the relationships among geology, structure, and geochemistry. The results provide greater insight into regional geochemical domains of mineralization and in the modeling of spatial associations of known ore deposits within the mining district. 1 Introduction The objective of this project was to build a spatial database of structural, lithological, and geochemical data, so that a spatial model for gold exploration could be created. This model was created using the Fuzzy Logic Method developed by Graeme Bonham-Carter of the Geologic Survey of Canada, and Gary Reins of the USGS. -

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
