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. -

WILLIAMS, Jr., and JANE G. FERRIGNO U.S. GEOLOGICAL SURVEY PROFESSIONAL PAPER 1386–K About 5 percent (about 75,000 km2) of Alaska is presently glacierized, including 11 mountain ranges, 1 large island, an island chain, and 1 archipelago. The total number of glaciers in Alaska is estimated at >100,000, including many active and former tidewater glaciers. Glaciers in every mountain range and island group are experiencing significant retreat, thinning, and (or) stagnation, especially those at lower elevations, a process that began by the middle of the 19th century. In southeastern Alaska and western Canada, 205 glaciers have a history of surging; in the same region, at least 53 present and 7 former large ice-dammed lakes have produced jökulhlaups (glacier-outburst floods). Ice-capped Alaska volcanoes also have the potential for jökulhlaups caused by subglacier volcanic and geothermal activity. Satellite remote sensing provides the only practical means of monitoring regional changes in glaciers in response to short- and long-term changes in the maritime and continental climates of Alaska. Geospatial analysis is used to define selected glaciological parameters in the eastern part of the Alaska Range. -

Introduction The digital map and this report focus on the two glacial limits that can most confidently be determined across the This report summarises the results of a collaborative effort state (Fig. 1): (1) the maximum extent of glaciers; and (2) among glacial geologists working in Alaska to produce an the Late Wisconsinan. The maximum extent of glaciers updated compilation of statewide glacier extents. It largely coincides with the outer limit of drift mapped by summarises evidence used to draw glacial limits in 15 Coulter et al. (1965). It does not represent a single ice regions across the state and highlights the most significant advance, but ranges in age from late Tertiary (e.g., the changes from previous mapping. This report also provides Nenana River valley) to Middle Pleistocene (e.g., the an overview of the glacial-geological record in Alaska, Baldwin Peninsula). The placement of the maximum glacial identifies prior efforts to synthesise data on Alaskan glacial limit in many places is essentially an educated guess, based geology and briefly discusses the broader implications of on extrapolation of limited data and guided by regional the newly mapped glacial extents. -

Forest and Fire Management Plan for Native Allotments in the Bering Straits Region of Alaska
Kawerak, Incorporated Forest and Fire Management Plan For Native Allotments in the Bering Straits Region of Alaska Prepared by Will Putman, CF Jake Sprankle, CF Doug Hanson, CF Tanana Chiefs Conference Forestry Program Fairbanks, Alaska April 18, 2008 Forest and Fire Management Plan For Native Allotments in the Bering Straits Region of Alaska Kawerak, Inc. _______________________________ Title: _______________________________ Date: _______________________________ Bureau of Indian Affairs Alaska Regional Office _______________________________ Title: _______________________________ Date: _______________________________ Forest and Fire Management Plan for Native Allotments in the Bering Straits Region of Alaska Executive Summary Within the Bering Straits region of Alaska, there are 636 pending, approved and certified Native allotments. Because each allotment may consist of as many as four parcels, there are a total 1,018 individual allotment parcels. The total area of these parcels covers 79,965 acres. The United States government is trustee of these allotted lands, and as such has management responsibilities on these lands, including the assurance that these lands and their resources are managed in perpetuity for the benefit of their Native Alaskan owners. Kawerak, Inc., through an Indian Self Governance Compact agreement with the U.S. Government, has assumed forest management activities on Native allotments within this region. An important element of this trust responsibility is also the protection of the land and resources from damaging wildland fires. This document is a programmatic plan designed to guide Kawerak, Inc. in fulfilling it’s trust responsibilities, and serves as both the forest management plan and the fire management plan for Native allotments within the Bering Straits region. The plan was prepared by Tanana Chiefs Conference Forestry Program under contract with Kawerak, Inc. -

WILTSE ACTING STATE GEOLOGIST 1995 SHORT NOTES ON ALASKA GEOLOGY 1995 Edited by Rodney A. Combellick and Fran Tannian Cover design by Ann-Lillian C. Schell Professional Report 117 Front cover: Exposure of till and outwash of the Elmendorf glacial advance at Goose Bay, west side of Knik Arm. (See paper by Reger and others, page 33.) Geologist Richard Reger examines Goose Bay peat of mid- Pleistocene age. Photograph by R.A. Combellick. Fairbanks, Alaska 1995 FOREWORD The Alaska Division of Geological & Geophysical Surveys (DGGS) here presents Short Notes on Alaska Geology 1995, the ninth issue in this series. There are ten papers, two each in Quaternary geology, structural geology, stratigraphy-sedimentology, and paleontology, and one each in economic geology and geochemistry. Almost all geo- graphic regions of the State are represented. Overall, they reflect the wide range of subjects and broad geographic distribution of current geologic research in Alaska. I want to take this opportunity to recognize the contributions of Tom Smith and Dick Reger, veteran DGGS geologists retiring this year, for their long service with DGGS (14 years and 19 years, respec- tively) and contributions to Alaskan geology. Tom began his Alaskan work in 1966 as a geophysicist; I knew him best during his six years STATE OF ALASKA (1975–81) with the University of Alaska Fairbanks (UAF). Since 1981 Tony Knowles, Governor Tom has served with DGGS–for the last four years as state geologist and director.
