The development of the fruit industry caused much of the valley land to be broken up into small parcels that were practical for fruit- growing. The large, open range live- stock operations that are common in many parts of the West are unusual in the North Fork. The Campbells’ present operation is actually made up of seven different original homesteads, nearly all of which were in fruit at one time. It is now the largest area of open space be- tween Hotchkiss and Paonia. The de- mand for land for housing subdivisions is moderate in the North Fork, compared to other parts of Colorado. But even this demand has caused real estate prices to increase. This demand is hampering ranchers from adding additional proper- ty to their land base.

    Final Report on the 2006 Ponderosa Campground Prescribed Burn Survey, Curecanti National Recreation Area, Gunnison County, Colorado Robert H. Brunswig, Ph.D. Anthropology Program School of Social Sciences University of Northern Colorado Greeley, Colorado 2006 Project Undertaken for the National Park Service as a partner of the Rocky Mountains Cooperative Ecosystem Studies Unit (RM-CESU) RM-CESU Cooperative Agreement No. H1200040001 Executive Summary The University of Northern Colorado, under contract to the National Park Service, conducted an archeological survey of Ponderosa Campground, Curecanti National Recreation Area, on July 28, 2006. The survey was done as part of an archeological inventory for a larger prescribed burn program under the National Wildlife-Urban Interface (WUI) Program. One small prehistoric site and four isolated finds, associated with ephemeral hunting-gathering activities were documented. The survey’s documented cultural resources, when viewed locally and regionally, fit within an annual, seasonal cycle of subsistence procurement and processing common to the region over the past several millennia. ii Table of Contents Introduction....................................................................................................................... 1 Environmental Context .................................................................................................... 3 Geology............................................................................................................................... 3 Soils....................................................................................................................................

    THE PROPOSED GUNNISON FOREST RESERVE COLORADO _________ Examination, Report, and Recommendations By Smith Riley _________ Bureau of Forestry U.S. Department of Agriculture 1904 A facsimile of a copy acquired from the National Archives and Records Administration, Rocky Mountain Regional Office at Denver Federal Center February 24, 2005 by David Bradford. 1 The Proposed Gunnison Forest Reserve, Colorado ________ Location – Area – Topography The proposed Gunnison Forest Reserve is in Central Western Colorado, lying mostly in the Gunnison County with small projections into Delta and Montrose Counties. Designed largely to protect the flow of the Gunnison River, it covers the northern and eastern watershed of that stream, including the West Elk Mountains, Fossil Ridge, and all the mountainous area on the headwaters of Taylor and East Rivers. It contains 929,704 acres, and is 72 miles from east to west and 36 miles from north to south. The larger portion of the Tin Cup, Italian Mountain, Crested Butte, and Sunset mining districts are within the area. Only mountain lands are included, the higher points being between 13,000 and 14,000 feet in altitude, and the lowest limits between 7,000 and 8,000 feet. With the exception of the Taylor Park district and the Black Mesa, just above the Gunnison Canon, the entire area is rough in the extreme and difficult to traverse. The streams rising in the West Elk Mountains flow in deep rough canons which divide the lower south and west slopes into many mesas. The Taylor Park district is precipitous along the divide, and breaks off to tough mountainous country just above the south line of the reserve.

  • Appendix 1: Citizen Conservation Proposal
    Appendix 1: Citizen Conservation Proposal Abrams Mountain Scenic Special Interest Area Proposed Designated Area Uncompahgre National Forest 3,000 acres Ouray Ranger District General Description At 12,801 feet, Abrams Mountain (aka Mount Abrams), is an iconic peak that rises steeply and directly above the city of Ouray and can be viewed for many miles while driving from Montrose toward Ouray. It is the centerpiece landscape feature for the City of Ouray and surrounding area. Gray Copper Falls and several other falls are outstanding scenic features just west of Brown Mountain. There are several historic mines on the slopes of Abrams Mountain and Brown Mountain. Elk, deer and bighorn sheep use the area. The area is not identified as a Colorado Roadless Area. Scenic Values Mount Abrams dominates the San Juan Skyway Scenic Byway for most of its length from Red Mountain Pass across Ironton Park. Its lush green slopes provide a spectacular backdrop to Ouray during the summer, and it is equally beautiful in the winter. From the summit, there are spectacular views to the south of the Red Mountains (1,2,3) and across the valley to Hayden Mountain. Abrams Mountain is part of the long four-mile Brown Mountain ridge, which rises up and down several summits to a high point of 13,339 feet that is the official summit of Brown Mountain. Also known as Duco Mountain, it is identified by a benchmark on the summit. The spectacular Gray Copper Falls and trail is directly west of the Brown Mountain summit. The upper end of the Gray Copper Falls trail intersects with a popular jeep trail spur off the Corkscrew Pass road near the Vernon mine, but the Gray Copper Falls Trail offers visitors a beautiful hike to see the falls.

  • Constraining the Timing of River Incision in the Upper Colorado Drainage Basin Using Apatite (U-Th)/He Thermochronology in the Elk Mountains, Western Colorado
    Constraining the Timing of River Incision in the Upper Colorado Drainage Basin Using Apatite (U-Th)/He Thermochronology in the Elk Mountains, Western Colorado Coleman Hiett Department of Geological Sciences University of Colorado, Boulder Departmental Honors Thesis April 10, 2017 Thesis Advisor: Lon Abbott, Department of Geological Sciences Defense Committee Members: Charles Stern, Department of Geological Sciences Lisa Barlow, Baker Residential Academic Program ABSTRACT This study utilizes apatite (U-Th)/He, or AHe, to produce a vertical transect of cooling histories along the height of the partially exhumed Crystal Pluton in the Elk Mountains of west/central Colorado. These cooling histories are interpreted to reflect exhumation controlled by the incision of the Crystal River – a tributary of the Colorado River. A period of rapid exhumation is observed from 8 – 11 Ma, likely beginning earlier, that is consistent with previous AHe data taken from nearby exhumed plutons in the Elk and northern West Elk Mountains. This period of exhumation predates the incision of a low relief surface that developed in northwestern Colorado by ca. 10 Ma, and is therefore not believed to have been controlled by the incision of the Colorado River. A review of previously noted incision constraints suggests that post-10 Ma Colorado River incision has become more rapid in the last 1 – 3 Ma, suggesting that climate change, rather than epeirogenic uplift, is the major driver for recent river incision. 1. INTRODUCTION 1.1 Concerns of the Colorado River For more than a century, geologists have struggled to better understand the geologic evolution of the western United States.

ALPINE VASCULAR FLORA OF THE RUBY RANGE, WEST ELK MOUNTAINS, COLORADO Emily L. Hartman and Mary Lou Rottnian Abstract —The Ruby Range is a northern extension of the West Elk Mountains of west central Colorado. Composed primarily of sedimentary rocks, the range is heavily faulted and intruded by many dikes and sills. Eight study areas, selected as representative of the major topographic features of the range, were analyzed floristically. A vascular flora of 220 species in 111 genera and 35 families is reported. The phytogeographic distribution of the flora is primarily alpine and western North American. The flora of the Ruby Range shows a 74% similarity to the flora of the San Juan Mountains to the southwest. The Ruby Range, a northern extension of composed of either quartz monzonite por- the West Elk Mountains (Prather 1982) of phyry, granodiorite porphyry, or dacite por- west central Colorado, is west of the Conti- phyry are intruded into the sedimentary for- nental Divide between 107 degrees 05 min- mations.
