Alaska Range
Alaska Range Introduction The heavily glacierized Alaska Range consists of a number of adjacent and discrete mountain ranges that extend in an arc more than 750 km long (figs. 1, 381). From east to west, named ranges include the Nutzotin, Mentas- ta, Amphitheater, Clearwater, Tokosha, Kichatna, Teocalli, Tordrillo, Terra Cotta, and Revelation Mountains. This arcuate mountain massif spans the area from the White River, just east of the Canadian Border, to Merrill Pass on the western side of Cook Inlet southwest of Anchorage. Many of the indi- Figure 381.—Index map of vidual ranges support glaciers.

Index glaciers range in size from tiny unnamed cirque glaciers with areas of less map modified from Field than 1 km2 to very large valley glaciers with lengths up to 76 km (Denton (1975a).

Alaska Range glaciers extend in elevation from above 6,000 m, near the summit of Mount McKinley, to slightly more than 100 m above sea level at Capps and Triumvi- rate Glaciers in the southwestern part of the range. -

Wrangell-St. Elias National Park and Preserve, Denali
Central Alaska Network Geologic Resources Evaluation Scoping Meeting Summary A geologic resources evaluation (GRE) scoping meeting was held from February 24 through 26, 2004 at the NPS regional office in Anchorage, Alaska to discuss geologic mapping in and around the parks and geologic resources management issues and concerns. The scoping meeting covered the three parks in the Central Alaska Network (CAKN) – Wrangell-St. Elias National Park and Preserve (WRST), Denali National Park and Preserve (DENA), and Yukon Charley Rivers National Preserve (YUCH). A summary of the status of geologic mapping and resource management issues is presented separately for each of these parks. The scoping summary is supplemented with additional geologic information from park planning documents, websites and NPS Geologic Resources Division documents. Purpose of the Geologic Resources Evaluation Program Geologic resources serve as the foundation of the park ecosystems and yield important information needed for park decision making. The National Park Service Natural Resource Challenge, an action plan to advance the management and protection of park resources, has focused efforts to inventory the natural resources of parks. The geologic component is carried out by the Geologic Resource Evaluation (GRE) Program administered by the NPS Geologic Resource Division. The goal of the GRE Program is to provide each of the identified 274 “Natural Area” parks with a digital geologic map, a geologic evaluation report, and a geologic bibliography. Each product is a tool to support the stewardship of park resources and each is designed to be user friendly to non-geoscientists. The GRE teams hold scoping meetings at parks to review available data on the geology of a particular park and to discuss the geologic issues in the park. -

Thus, we’ve teamed up with the American Breast Cancer Foundation, an organization that is doing their part to save our world, one breast at a time, in order to do our part, in hopes of becoming role models and encouraging the rest of the world to do their part too. So here’s our plan: We are going to climb Denali (Mount McKinley) via the West Buttress route in June of 2006. -

Other Bering Sea, Chukchi Sea, Gulf of Alaska, and the Pacific objectives are to describe geological hazards (i.e., Ocean. volcanic and seismic hazards) and geological resources (i.e., mineral and fossil fuel resources), and to describe the scientific, economic, and social significance of the earth for this region. As an example, the figure on the last page illustrates earthquakes belts for this dangerous part of the globe. What is the Northern Cordillera? The Northern Cordillera is comprised of Alaska and Western Canada. Alaska contains a series of parallel mountain ranges, and intervening topographic basins and plateaus. From north to south, the major mountain ranges are the Brooks Range, Kuskokwim Mountains, Aleutian Range, Alaska Range, Wrangell Mountains, and the Chugach Mountains. -

North America Summary, 1968
240 CLIMBS A~D REGIONAL ?\OTES North America Summary, 1968. Climbing activity in both Alaska and Canada subsided mar kedly from the peak in 1967 when both regions were celebrating their centen nials. The lessened activity seems also to have spread to other sections too for new routes and first ascents were considerably fewer. In Alaska probably the outstanding climb from the standpoint of difficulty was the fourth ascent of Mount Foraker, where a four-man party (Warren Bleser, Alex Birtulis, Hans Baer, Peter Williams) opened a new route up the central rib of the South face. Late in June this party flew in from Talkeetna to the Lacuna glacier. By 11 July they had established their Base Camp at the foot of the South face and started up the rib. This involved 10,000 ft of ice and rotten rock at an angle of 65°. In the next two weeks three camps were estab lished, the highest at 13,000 ft. Here, it was decided to make an all-out push for the summit. On 24 July two of the climbers started ahead to prepare a route. In twenty-eight hours of steady going they finally reached a suitable spot for a bivouac. The other two men who started long after them reached the same place in ten hours of steady going utilising the steps, fixed ropes and pitons left by the first party. After a night in the bivouac, the two groups then contin ued together and reached the summit, 17,300 ft, on 25 July. They were forced to bivouac another night on the return before reaching their high camp. -
