TORDRILLO MOUNTAIN LODGE 7 a 8 helicopter operations The helicopter operations of Chugach Adventure Guides (CAG) was founded as Chugach Powder Guides (CPG). Alaska was just starting to come on the world scene as a recognized leader in backcountry ski terrain. Much of the Alaskan reputation was garnered from magazine hype and events such as the World Extreme Skiing Championships. CPG realized that the immense Chugach Range isn't just for adrenaline junkies alone. Since 1998 CPG helicopters have flown and opened up the finest backcountry skiing/boarding in the world. Considering our pioneering of the Tordrillos and the Chugach, we have cataloged over 500 runs and thou- sands of landings. Our terrain and reputation have brought ski and snowboard enthusiasts from around the world to experience Alaska’s mountains. experience the excitement and magnitude of heli skiing/boarding alaska T: 907-783-4354 :: F: 907-783-4355 :: www.chugachadventureguides.com :: P.O.

  • 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. The total glacier area of the Alaska Range is the Alaska Range showing 2 approximately 13,900 km (Post and Meier, 1980, p. 45). Its several thousand the glacierized areas. 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.

  • A New Satellite-Derived Glacier Inventory for Western Alaska
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2011 A new satellite-derived glacier inventory for western Alaska Le Bris, R ; Paul, F ; Frey, H ; Bolch, T Abstract: Glacier inventories provide the baseline data to perform climate-change impact assessment on a regional scale in a consistent and spatially representative manner. In particular, a more accurate calculation of the current and future contribution to global sea-level rise from heavily glacierized re- gions such as Alaska is much needed. We present a new glacier inventory for a large part of western Alaska (including Kenai Peninsula and the Tordrillo, Chigmit and Chugach mountains), derived from nine Landsat Thematic Mapper scenes acquired between 2005 and 2009 using well-established automated glacier-mapping techniques (band ratio). Because many glaciers are covered by optically thick debris or volcanic ash and partly calve into water, outlines were manually edited in these wrongly classified regions during post-processing. In total we mapped ฀8830 glaciers (>0.02 km2) with a total area of ฀16 250 km2. Large parts of the area (47%) are covered by a few (31) large (>100 km2) glaciers, while glaciers less than 1 km2 constitute only 7.5% of the total area but 86% of the total number. We found a strong dependence of mean glacier elevation on distance from the ocean and only a weak one on aspect. Glacier area changes were calculated for a subset of 347 selected glaciers by comparison with the Digital Line Graph outlines from the US Geological Survey.

  • Ring of Fire Proposed RMP Final EIS Volume 3
    Ring of Fire Proposed RMP/Final EIS EXECUTIVE SUMMARY The Anchorage Field Office (AFO) of the Bureau of Land Management (BLM) has prepared a Proposed Resource Management Plan (PRMP)/Final Environmental Impact Statement (FEIS) for the Ring of Fire planning area to provide a comprehensive framework for managing and allocating uses of the public lands and resources within the Anchorage District. This planning process meets the requirements of the National Environmental Policy Act (NEPA) through a detailed description of the alternatives and environmental consequences resulting from each alternative. The Federal Land Policy and Management Act of 1976 (FLPMA) requires the Secretary of the Interior, with public involvement, to develop, maintain, and when appropriate, revise land use plans that provide tracts or areas for the use of the public lands. The Ring of Fire planning area encompasses an area from the Aleutian Islands at the southwestern tip of Alaska, through the Alaska Peninsula, parts of southcentral Alaska, through the southeast panhandle. The planning area is divided into four geographic regions: Alaska Peninsula/Aleutian Chain region, Kodiak region, southcentral region, and southeast region. Reasonably Foreseeable Development (RFD) scenarios provide a mechanism to analyze the effects that discretionary planning decisions have on mineral development based upon four alternatives. This RFD scenario is used to predict the type, location, and manner of potential disturbance due locatable minerals extraction in the planning area over the next 15 years. This report has been formulated to project and predict development regardless of specific land management authority (federal, State, Native, or private), but concentrates on the high mineral potential areas located on unencumbered BLM lands and State- and Native-selected lands.
