    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.

All written comments received during the comment period would be made available to the public and considered during Final EA preparation. The provision of private address information with your comment is voluntary and would not be released for any other purpose unless required by law. However, this information is used to compile the project mailing list and failure to provide it would result in your name not being included on the mailing list. August 2011 DRAFT FINDING OF NO SIGNIFICANT IMPACT (FONSI) INTRODUCTION -The Air Force is interested in obtaining public and agency comments on this revised proposal to designate a low altitude training area for training Air Force Special Operations Command (AFSOC) aircrews. This Draft FONSI is provided as part of the attached Environmental Assessment for public and agency review. NAME OF PROPOSED ACTION - Establishment of Low Altitude Training for Cannon AFB, New Mexico. DESCRIPTION OF THE PROPOSED ACTION AND NO ACTION ALTERNATIVE - The United States Air Force (Air Force) proposes to designate a low altitude training area in northern New Mexico and southern Colorado where 27 Special Operations Wing (27 SOW) aircrews operating from Cannon AFB would train for worldwide operations under their global response commitment. Cannon AFB based MC-130J and CV-22 aircraft rely on darkness, terrain, and low altitude to provide masking during missions. 27 SOW aircrews are required to maintain flight proficiency in varying terrain including mountainous terrain, varying threat levels, different climatic conditions, and low altitude after dark missions to support Special Operations Forces.

  • Request for Council Action
    REQUEST FOR COUNCIL ACTION Date: July 22, 2013 Item No.: 14.a Department Approval City Manager Approval Item Description: Discuss Redevelopment of the Hagen Property at 2785 Fairview Ave. and Authorize Application for a Minnesota DEED grant. 1 BACKGROUND 2 The Hagen property, located at 2785 Fairview Ave, currently contains a multi-tenant trucking terminal. 3 In 2009, the City purchased approximately 2.05 acres of the property for future Twin Lakes right-of- 4 way. The City was recently approached by representatives of the property and a developer regarding 5 the redevelopment of the remaining 5.83 acres of the Hagen property. 6 7 The developer, Sherman Associates, Inc. is proposing to construct a three-phase project over a three- 8 year period beginning in the spring of 2014. Phase 1 would result in approximately 110 units of market 9 rate rental housing. Phase 2 would feature approximately 6,000 square feet of office/retail. Phase 3 10 would provide approximately 65-80 units of mixed-income rental housing. All units of housing would 11 be non-age restricted. Approximately 80% of the housing units in Phase 3 will be market rate, with the 12 remaining 20% targeted for households earning at or below 50% of area median income (AMI). A 13 project narrative, site plan, and company background are included in Attachment B. 14 As part of the preliminary discussion with staff, the developers have identified a financing gap to 15 construct the project as proposed. As one way to help close the financial gap, the developer and staff 16 have been working on an application for a redevelopment grant from the Minnesota Department of 17 Employment and Economic Development (DEED).

  • Naturally Occurring Acid Rock Drainage In
    IMPACTS ON WATER QUALITY AND BIOTA FROM NATURAL ACID ROCK DRAINAGE IN COLORADO’S LAKE CREEK WATERSHED1 David A. Bird2, Matthew A. Sares, Greg A. Policky, Travis S. Schmidt, and Stanley E. Church Abstract. Colorado’s Lake Creek watershed hosts natural acid rock drainage that significantly impacts surface water, streambed sediment, and aquatic life. The source of the ARD is a group of iron-rich springs that emerge from intensely hydrothermally altered, unexploited, low-grade porphyry copper mineralization in the Grizzly Peak Caldera. Source water chemistry includes pH of 2.5 and dissolved metal concentrations of up to 277 mg/L aluminum, 498 mg/L iron, and 10 mg/L copper. From the hydrothermally altered area downstream for 27 kilometers to Twin Lakes Reservoir, metal concentrations in streambed sediment are elevated and the watershed experiences locally severe adverse impacts to aquatic life due to the acidic, metal-laden water. The water and sediment quality of Twin Lakes Reservoir is sufficiently improved that the reservoir supports a trout fishery, and remnants of upstream ARD are negligible.

Church Abstract. Colorado’s Lake Creek watershed hosts natural acid rock drainage that significantly impacts surface water, streambed sediment, and aquatic life. The source of the ARD is a group of iron-rich springs that emerge from intensely hydrothermally altered, unexploited, low-grade porphyry copper mineralization in the Grizzly Peak Caldera. Source water chemistry includes pH of 2.5 and dissolved metal concentrations of up to 277 mg/L aluminum, 498 mg/L iron, and 10 mg/L copper. From the hydrothermally altered area downstream for 27 kilometers to Twin Lakes Reservoir, metal concentrations in streambed sediment are elevated and the watershed experiences locally severe adverse impacts to aquatic life due to the acidic, metal-laden water. The water and sediment quality of Twin Lakes Reservoir is sufficiently improved that the reservoir supports a trout fishery, and remnants of upstream ARD are negligible.
