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. -

Observations of Migrating Golden Eagles (Aquila Chrysaetos) in Eastern Interior Alaska Offer Insights on Population Size and Migration Monitoring

OBSERVATIONS OF MIGRATING GOLDEN EAGLES (AQUILA CHRYSAETOS) IN EASTERN INTERIOR ALASKA OFFER INSIGHTS ON POPULATION SIZE AND MIGRATION MONITORING 1 CAROL L. MCINTYRE Denali National Park and Preserve, 4175 Geist Road, Fairbanks, AK 99709 U.S.A. STEPHEN B. LEWIS U.S. Fish and Wildlife Service, 3000 Vintage Boulevard, Suite 201, Juneau, AK 99801 U.S.A. ABSTRACT.—Migratory Golden Eagles (Aquila chrysaetos) from Alaska winter across a vast region of western North America, much of which is undergoing rapid change from a diversity of indirect and direct human activities. To address recent conservation concerns, we are studying the year-round movements of migratory Golden Eagles from interior and northern Alaska to identify and evaluate potential risks to their survival. We are also developing new survey techniques to estimate population size and trends. As part of our ongoing studies, we observed migrating Golden Eagles in spring and autumn 2014 during field investigations to locate Golden Eagle capture sites in eastern interior Alaska, and in spring 2015 during capture activities. We observed large numbers of Golden Eagles in both spring and autumn, suggesting that the Mentasta Mountains are an important migration corridor for this species. Further, our observations, including 1364 migrating Golden Eagles in October 2014, suggested that the Alaska Golden Eagle population is much larger than is reflected in the only currently available statewide population estimate of 2400 eagles. In combination with historical and contemporary tracking studies, our observations in the Mentasta Mountains provide important new information about Golden Eagle migration in Alaska and stimulate interest in answering fundamental questions about using counts of migrating Golden Eagles to estimate, and detect change in, the population size of Alaska’s migratory Golden Eagles. -

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.

MOUNT SAINT ELIAS As I Was Ascending Mount Logan in 1991
Mount Saint E lia s- Southwest Buttress R u e d i H o m b e r g e r , Schweizer Alpen Club In Memory of Miroslav Šmid I FIRST SAW MOUNT SAINT ELIAS as I was ascending Mount Logan in 1991. The plan to climb this magnificent peak developed slowly. As the highest coastal mountain, it would have been intriguing to climb it, by fair means, directly from sea level from the edge of the ocean at Icy Bay. In the end, however, the route won out which the International Boundary Survey Party had pioneered in 1913 but not completed. I also knew Paul Claus very well; he is the specialized glacier pilot for this region. This offered us the best solution to the transport problems with the long distances and difficult weather conditions. I was closely bound to Miroslav Šmid, called “Mira,” by a fifteen-year-long friendship. We had ventured together in the Pamir, the Alps, the Himalaya and in his own Czech technically-difficult sandstone towers. He was to be our group’s guest of honor. At the beginning of May, we all met in Anchorage and began a giant birthday party, which continued three days later on the Nebesna Glacier. Mira’s birthday and mine were only three days apart and collectively we were 99 years old. But the Nebesna Glacier does not flow off Saint Elias. Why were we there? I first informed Mira and my other friends when we were on the glacier. Paul Claus had simply set us off on the northeast side of Mount Blackburn so that we could acclimatize.
