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).

Oil, Natural Gas and Helium Potential of the Chupadera Mesa Area, Lincoln and Socorro Counties, New Mexico
Oil, natural gas and helium potential of the Chupadera Mesa area, Lincoln and Socorro Counties, New Mexico by Ronald F. Broadhead and Glen Jones February 27, 2004 New Mexico Bureau of Geology and Mineral Resources A division of New Mexico Institute of Mining and Technology Socorro, NM 87801 Oil, natural gas and helium potential of the Chupadera Mesa area, Lincoln and Socorro Counties, New Mexico By Ronald F. Broadhead1 and Glen Jones2 1 Principal Petroleum Geologist and 2 Assistant Director for Computer/Internet Services New Mexico Bureau of Geology and Mineral Resources, a division of New Mexico Institute of Mining and Technology, Socorro, NM 87801 ABSTRACT The Chupadera Mesa region encompasses 3900 mi2 in eastern Socorro and western Lincoln Counties, central New Mexico. The area includes varied geological elements including the broad Jornada del Muerto Basin in the west, and the Oscura Mountains and Chupadera Mesa in the medial area. The Laramide-age Sierra Blanca Basin and several isolated mountain ranges formed principally by Tertiary-age igneous intrusive bodies occupy the eastern third of the region. The Chupadera Mesa area has been sparsely drilled. A total of 45 wells have been drilled within the project area. This is a density of approximately one well for every 85 mi2. Many of the wells are shallow and reached total depth in Permian strata. Only 20 wells have been drilled to Precambrian basement. This is a density of one well per 200 mi2, or 6.4 townships. Neither oil, natural gas nor helium production have been established. Nevertheless, several of the wells have encountered promising shows of oil, natural gas, and helium. -

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. -

Sunlight Peak Class 4 Exposure: Summit Elev
Sunlight Peak Class 4 Exposure: Summit Elev.: 14,066 feet Trailhead Elev.: 11,100 feet Elevation Gain: 3,000' starting at Chicago Basin 6,000' starting at Needleton RT Length: 5.00 miles starting at Chicago Basin 19 miles starting at Needleton Climbers: Rick, Brett and Wayne Crandall; Rick Peckham August 8, 2012 I’ve been looking at climbing reports to Sunlight Peak for a few years – a definite notch up for me, so the right things aligned and my son Brett (Class 5 climber), brother Wayne (strong, younger but this would be his first fourteener success) and friend Rick Peckham from Alaska converged with me in Durango to embark on a classic Colorado adventure with many elements. We overnighted in Durango, stocking up on “essential ingredients” for a two-night camp in an area called the Chicago Basin, which as you will see, takes some doing to get to. Durango, founded in 1880 by the Denver & Rio Grande Railway company, is now southwest Colorado’s largest town, with 15,000 people. Left to right: Brett, Rick, Wayne provisioning essentials. Chicago Basin is at the foot of three fourteeners in the San Juan range that can only be reached by taking Colorado’s historic and still running (after 130 years) narrow-gauge train from Durango to Silverton and paying a fee to get off with back-pack in the middle of the ride. Once left behind, the next leg of the excursion is a 7 mile back-pack while climbing 3000’ vertical feet to the Basin where camp is set. -

As agreed with your office, we gathered information on areas managed by two agencies: the Department of the Interior’s Bureau of Land Management (BLN) and the Department of Agriculture’s Forest Service. Specifically, this report provides information on (1) legislative guidance and the agency policies governing wilderness study area management, (2) the various activities and uses occurring in the agencies’ study areas, (3) the ways these activities and uses affect the areas, and (4) agency actions to monitor and restrict these uses and to repair damage resulting from them. Appendixes I and II provide data on the number, acreage, and locations of wilderness study areas managed by BLM and the Forest Service, as well as data on the types of uses occurring in the areas. -
2021 OHV Grant Recommended Funding Approval
State Trails Program 13787 US Hwy. 85 N., Littleton, Colorado 80125 P 303.791.1957 | F 303.470-0782 May 6-7, 2020 2020-2021 OHV Trail Grant funding awards as recommended by the State Recreational Trails Committee. This letter is a summary and explanation of the enclosed Colorado Parks and Wildlife (CPW) 2020-2021 OHV Trail Grant funding recommendations for Parks and Wildlife Commission (PWC) approval during the May 2020 meeting. We are requesting approval for 60 grants for a total award amount of $4,273,860. BACKGROUND INFORMATION: The Colorado Parks and Wildlife Division’s (CPW) Trails Program, a statewide program within CPW, administers grants for trail-related projects on an annual basis. Local, county, and state governments, federal agencies, special recreation districts, and non-profit organizations with management responsibilities over public lands may apply for and are eligible to receive non- motorized and motorized trail grants. Colorado’s Off-highway Vehicle Trail Program CPW’s OHV Program is statutorily created in sections 33-14.5-101 through 33-14.5-113, Colorado Revised Statutes. The program is funded through the sale of OHV registrations and use permits. It is estimated that almost 200,000 OHVs were registered or permitted for use in Colorado during the 2019-2020 season. The price of an annual OHV registration or use- permit is $25.25. Funds are used to support the statewide OHV Program, the OHV Registration Program and OHV Trail Grant Program, including OHV law enforcement. The OHV Program seeks to improve and enhance motorized recreation opportunities in Colorado while promoting safe, responsible use of OHVs.
