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. -

Crestone Peak … and a Self Rescue!
Crestone Peak … and a Self Rescue! Exposure: Summit Elev.: 14,294 feet Trailhead Elev.: 9,900 feet Elevation Gain: 5,700 feet starting at upper 4wd trailhead 3850 feet starting at S. Colony Lake camp Roundtrip: 14 miles starting at upper 4wd TH (9,900) 5 miles from S. Colony Lake camp Climbers: Rick Crandall, Rick Peckham 8/15/2015 Crestone Peak, or “The Peak” as known among many climbers, is one of the “double-black diamond” 14ers for climbers. It is located in the Sangre de Cristo range near to the town of Crestone. It and its companion fourteener, Crestone Needle were the last of all the fourteeners to be scaled back in the 1920’s. This remote and rugged mountain was once thought impossible to climb. The name comes from the famous “crete du coq” (cocks comb) on the Italian side of the Matterhorn which was anglicized to Crestone. (From Fourteen Thousand Feet, by John L. Jerome Hart, June, 1925) The easiest route is not the shortest or most direct. 800 feet of elevation must be lost and regained over Broken Hand Pass, which is a 1500’ climb from the South Colony Lake, and then another 2,000 feet must be climbed up the sustained Red Couloir to the summit approach. All climbing is rated at least Class 3. Considerable climbing experience is recommended before attempting this formidable mountain. Crestone Peak – a magnificent mountain. We had plenty of warnings about this mountain, including from Mountain Rescue as you see in the unfolding story. “Crestone Peak is one of the more dangerous fourteener climbs in Colorado; accidents occur often in the Crestones, some caused by falls and others by lightning (a daily summer occurrence in the Sangre de Cristos).” From Summit Post: Adding to the difficulty of the climb is getting there. -

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 -

WRHR Route Description
Wind River High Route !Section 1: Green River Lakes Trailhead to Upper Indian Basin! ! The hike starts with the gentlest of introductions. A mellow wander up the flat and scenic drainage of the Green River for the first few hours, with excellent views of Squaretop Mountain. From the Green River Lakes trailhead, take the trail that heads along the eastern shore of the two turquoise colored Green River Lakes. This trail is marked as both the Highline Trail and the Continental Divide Trail. After passing the two lakes, the trail begins a very gradual climb toward Three Forks Park, which is reached after several hours of hiking. At Three Forks Park the trail turns abruptly west and you begin your ascent into the high country, climbing to just above 10000 feet and over Vista Pass. A slight drop and then a climb into a rocky basin towards Cube Rock Pass will bring you above 10000 feet once again. The High Route will stay above 10000 feet for the next 5 or 6 days, not dropping below this barrier until the final hike out to the car, just !a few miles from the Big Sandy Trailhead.! From Cube Rock Pass continue on the trail toward Peak Lake. There is decent camping on the west side of Peak Lake, but even better camping in the basin just east of the lake. From the outlet of Peak Lake, curve around its north shore, passing through a large talus slide that drops all the way to the shore. Then wander east toward Knapsack Col. -

In Memoriam TERRIS MOORE 1908-1993 Terris Moore, age 85, of Cambridge, Massachusetts, explorer, mountaineer, light-plane pilot and President Emeritus of the University of Alaska, died on November 7 after a massive heart attack. He became internationally known in 1932 when he and three companions reached and surveyed Minya Konka (now called Gongga Shan) in Sichuan, China. Moore and Richard Burdsall, both AAC members, ascended this very difficult mountain (that Burdsall and Arthur Emmons surveyed as 24,490 feet high), and in doing so climbed several thousand feet higher than Americans had gone before. At the time, Moore was the outstanding American climber. Moore, Terry to his friends, was born in Haddonfield, New Jersey, on April 11, 1908 and attended schools in Haddonfield, Philadelphia and New York before entering and graduating from Williams College, where he captained the cross-country team and became an avid skier. After graduating from college, he attended the Harvard School of Business Administration, from which he received two degrees: Master of Business Administration and Doctor of Commercial Science. Terry’s mountain climbing had begun long before this time. In 1927, he climbed Chimborazo (20,702 feet) in Ecuador and made the first ascent of 17,159-foot Sangai, an active volcano there. Three years later, he joined the Harvard Mountaineering Club and also became a member of the American Alpine Club, connections which led that year to his making the first ascent of 16,400-foot Mount Bona in Alaska with Allen Carp& and the first unguided ascent of Mount Robson in the Canadian Rockies. -
Wind River Expedition Through the Wilderness… a Journey to Holiness July 17-23, 2016
Wind River Expedition Through the Wilderness… a Journey to Holiness July 17-23, 2016 Greetings Mountain Men, John Muir once penned the motivational quote… “The mountains are calling and I must go.” And while I wholeheartedly agree with Muir, I more deeply sense that we are responding to the “Still Small Voice”, the heart of God calling us upward to high places. And when God calls we must answer, for to do so is to embark on an adventure like no other! Through the mountain wilderness Moses, Elijah, and Jesus were all faced with the holiness and power of God. That is our goal and our deepest desire. Pray for nothing short of this my friends and be ready for what God has in store… it’s sure to be awesome! Please read the entire information packet and then follow the simple steps below and get ready!
