Bailey Mark Hopkins 1980
AN ABSTRACT OF THE THESIS OF MARK H. BAILEY for the degree of Master of Science in Geology presented on June 7, 1979 Title: BEDROCK GEOLOGY OF WESTERN TAYLOR PARK, GUNNISON COUNTY, COLORADO Signature redacted for privacy. Abstract approved: I ._&V_j - Dr. Robert D. Lawrence The western Taylor Park area covers about 65 square miles on the western flank of the Sawatch Range. It is underlain chiefly by Precambrian rocks, partiallycovered on the east by glacial debris andoverlapped on the west and south by Paleozoic sedimentary rocks. The Precambrian rocks include a group ofmetasedimen- tary rocks of an undetermined age greaterthan 1700 m.y. The metasedimentary rocks include five mineralogicallydis- tinct units, quartzite, quartz-muscovite schist, quartz- epidote schist, quartz-plagioclase-biotite schist,and quartz-biotite-microcline-sillimaflite schist. The higher grade sillimanite-bearing biotite schists arerestricted to the western half of the map area and closelyassociated with the Forest Hill granitic rocks. The metasedimentary rocks were intruded twiceduring Precambrian time. The oldest intrusive event resulted in syntectonic emplacement of granodiorite and biotite tona- lite rocks. These rocks correlate with the 1700 m.y.old Denny Creek granodiorite gneiss and Kroenkegranodiorite which are mapped and informally named in the adjoining Mount Harvard quadrangle. The second, post-tectonic, igneous eventproduced granitic rocks that are dated at 1030 m.y. byRb-Sr meth- ods. These rocks include two comagmatic graniticphases, the Forest Hill porphyritic granite and the ForestHill cataclastic granite. A third phase, the Forest Hill horn- blende granodiorite, intrudes the porphyritic graniteand, therefore, is younger than the granitic phases. The 1030 m.y. -

Case 1:13-cv-01723-RBJ Document 91 Filed 06/27/14 USDC Colorado Page 1 of 36 IN THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF COLORADO Judge R. Brooke Jackson Civil Action No. 13-cv-01723-RBJ HIGH COUNTRY CONSERVATION ADVOCATES, WILDEARTH GUARDIANS, and SIERRA CLUB, Plaintiffs, v. UNITED STATES FOREST SERVICE, UNITED STATES DEPARTMENT OF AGRICULTURE, UNITED STATES BUREAU OF LAND MANAGEMENT, UNITED STATES DEPARTMENT OF THE INTERIOR, DANIEL JIRÓN, in his official capacity as Regional Forester for the U.S. Forest Service’s Rocky Mountain Region, SCOTT ARMENTROUT, in his official capacity as Supervisor of the Grand Mesa, Uncompahgre, and Gunnison National Forests, and RUTH WELCH, in her official capacity as the Bureau of Land Management’s Colorado State Office Acting Director, Defendants, and ARK LAND COMPANY, INC., and MOUNTAIN COAL COMPANY, L.L.C., Intervenor-Defendants. ORDER The North Fork Valley in western Colorado is blessed with valuable resources. The area hosts several coal mines as well as beautiful scenery, abundant wildlife, and outstanding recreational opportunities. And as is sometimes the case in rich places like this, people disagree about how to manage the development of those resources. In the case before the Court, the plaintiff environmental organizations seek judicial review of three agency decisions that together 1 Case 1:13-cv-01723-RBJ Document 91 Filed 06/27/14 USDC Colorado Page 2 of 36 authorized on-the-ground mining exploration activities in a part of the North Fork Valley called the Sunset Roadless Area. These exploration activities are scheduled to begin on July 1, 2014. -

IV. Motorized Recreation Route Recommendations
APPENDIX IV COHVCO – TPA –RMEC COMMENTS 6/1/09 IV. Motorized Recreation Route Recommendations The following roads and trails are recommended by COHVCO, in addition to those in the preliminary proposed alternative, and those submitted as a group recommendation in the Colorado 500 letter dated 15 September 2006. These are intended to be a part of an alternative in the DEIS that more fully responds and addresses a historic and enhanced motorized recreation transportation system for all federal lands in the Gunnison Basin. Recommendations 1. Trail 561 Eyrie Basin Trail. An historically used trail by miners and modern day single track motorcyclists. From Italian Creek Road, it drops steeply into Eyrie Creek Basin where it connects to the Taylor Park Road. This trail accesses private land, but has a landowner interested in maintaining public motorized use. 2. Trail 413 Matchless Mountain Trail. An historical use trail that is a single track motorcycle use trail leading from near the top of Matchless Mountain on the west to the west side of Taylor Reservoir where it heads north to a crossing of the Taylor River just above Rivers End Campground. Scenic route from a 12,300 foot peak to the Reservoir’s Edge, and ridden almost exclusively downhill. Access to Trail 413 is off of Trail 424, the Gunnison Spur Trail. It provides challenge for advanced riders in a low use area. 3. Trail 424 Spur Trail Connector. Connects from the Dinner Station Campground to Road 753.1. A historically used motorcycle trail. The route provides a continuity of access to the entire Spur Trail System from the Taylor Park Road. -
