  • 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).

  • 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.

  • Ecosystem-Based Chinook Salmon, Oncorhynchus
    Ecosystem-based Chinook Salmon Oncorhynchus tshawytscha Management Plan of the Susitna River Drainage Authors: William Middleton (primary contact), Allison Thomason, Ashley Williams, Abraham Meyer, David Pomelow Coach: Roger R. Saft, Ph.D. Assistant Coach: Wendy Garrett [email protected] Aurelia Wasilla High School 701 East Bogard Road Wasilla, Alaska 99654 Abstract The fishery is Susitna River chinook salmon (Oncorhynchus tshawytscha) fishery on the Northern Cook Inlet. It is the largest in size of all Pacific salmon species. Management of the fish, like any other natural resource in the state of Alaska, is controlled by the Alaska constitution. The requirement is to manage to achieve maximum benefit to the citizens of the state and to preserve the species by establishing and maintaining maximum sustained yield. Present to a lesser extent in the Susitna River drainage is the coho salmon (Oncorhynchus kisutch). Sockeye salmon (Oncorhynchus nerka) are a major contributor to the fisheries of the Upper Cook Inlet and the Susitna River system tributaries. Burbot (Lota lota) are a fish species present not of commercial significance. Present also in the Susitna River basin is the rainbow trout (Oncorhynchus mykiss). It is not managed for commercial harvest. Also inhabiting the drainage without commercial significance are Arctic grayling (Thymallus arcticus). The Susitna River chinook salmon fishery is one of the largest fisheries in Alaska and provides much of the world with salmon. It brings a large amount of revenue for the state and its citizens. Because of the large amount of fish and for the enjoyment, many sport fishermen go out and by fishing supplies and licenses so as to ensure that they catch a trophy fish.

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.
