NOTES on the BIRDS of CHIRIKOF ISLAND, ALASKA Jack J
NOTES ON THE BIRDS OF CHIRIKOF ISLAND, ALASKA JACK J. WITHROW, University of Alaska Museum, 907 Yukon Drive, Fairbanks, Alaska 99775; [email protected] ABSTRACT: Isolated in the western Gulf of Alaska 61 km from nearest land and 74 km southwest of the Kodiak archipelago, Chirikof Island has never seen a focused investigation of its avifauna. Annotated status and abundance for 89 species recorded during eight visits 2008–2014 presented here include eastern range extensions for three Beringian subspecies of the Pacific Wren (Troglodytes pacificus semidiensis), Song Sparrow (Melospiza melodia sanaka), and Gray-crowned Rosy-Finch (Leucost- icte tephrocotis griseonucha). A paucity of breeding bird species is thought to be a result of the long history of the presence of introduced cattle and introduced foxes (Vulpes lagopus), both of which persist to this day. Unique among sizable islands in southwestern Alaska, Chirikof Island (55° 50′ N 155° 37′ W) has escaped focused investigations of its avifauna, owing to its geographic isolation, lack of an all-weather anchorage, and absence of major seabird colonies. In contrast, nearly every other sizable island or group of islands in this region has been visited by biologists, and they or their data have added to the published literature on birds: the Aleutian Is- lands (Gibson and Byrd 2007), the Kodiak archipelago (Friedmann 1935), the Shumagin Islands (Bailey 1978), the Semidi Islands (Hatch and Hatch 1983a), the Sandman Reefs (Bailey and Faust 1980), and other, smaller islands off the Alaska Peninsula (Murie 1959, Bailey and Faust 1981, 1984). With the exception of most of the Kodiak archipelago these islands form part of the Alaska Maritime National Wildlife Refuge (AMNWR), and many of these publications are focused largely on seabirds. -

Analysis of the Accident on Air Guitar
Analysis of the accident on Air Guitar The Safety Committee of the Swedish Climbing Association Draft 2004-05-30 Preface The Swedish Climbing Association (SKF) Safety Committee’s overall purpose is to reduce the number of incidents and accidents in connection to climbing and associated activities, as well as to increase and spread the knowledge of related risks. The fatal accident on the route Air Guitar involved four failed pieces of protection and two experienced climbers. Such unusual circumstances ring a warning bell, calling for an especially careful investigation. The Safety Committee asked the American Alpine Club to perform a preliminary investigation, which was financed by a company formerly owned by one of the climbers. Using the report from the preliminary investigation together with additional material, the Safety Committee has analyzed the accident. The details and results of the analysis are published in this report. There is a large amount of relevant material, and it is impossible to include all of it in this report. The Safety Committee has been forced to select what has been judged to be the most relevant material. Additionally, the remoteness of the accident site, and the difficulty of analyzing the equipment have complicated the analysis. The causes of the accident can never be “proven” with certainty. This report is not the final word on the accident, and the conclusions may need to be changed if new information appears. However, we do believe we have been able to gather sufficient evidence in order to attempt an -

Gear Brands List & Lexicon
Gear Brands List & Lexicon Mountain climbing is an equipment intensive activity. Having good equipment in the mountains increases safety and your comfort level and therefore your chance of having a successful climb. Alpine Ascents does not sell equipment nor do we receive any outside incentive to recommend a particular brand name over another. Our recommendations are based on quality, experience and performance with your best interest in mind. This lexicon represents years of in-field knowledge and experience by a multitude of guides, teachers and climbers. We have found that by being well-equipped on climbs and expeditions our climbers are able to succeed in conditions that force other teams back. No matter which trip you are considering you can trust the gear selection has been carefully thought out to every last detail. People new to the sport often find gear purchasing a daunting chore. We recommend you examine our suggested brands closely to assist in your purchasing decisions and consider renting gear whenever possible. Begin preparing for your trip as far in advance as possible so that you may find sale items. As always we highly recommend consulting our staff of experts prior to making major equipment purchases. A Word on Layering One of the most frequently asked questions regarding outdoor equipment relates to clothing, specifically (and most importantly for safety and comfort), proper layering. There are Four basic layers you will need on most of our trips, including our Mount Rainier programs. They are illustrated below: Underwear -
Climb Antarctica Required Clothing and Equipment List
CLIMB ANTARCTICA REQUIRED CLOTHING AND EQUIPMENT LIST Conditions in Antarctica change drastically throughout our season and vary depending on your location. At Union Glacier, the climate is very dry and generally sunny but wind chill can impact temperatures greatly with early November being as cold as -22°F (-30°C). Average mid-season temperatures range from -12°F to 30°F (-24°C to -1°C). To be prepared for all conditions, it is important to have a selection of items you can mix and match. The layering system described below will keep you safe and comfortable in all conditions—it is also the same system utilized by our Antarctic field staff. You do not need to wear ALL of these layers ALL of the time. Dress for the weather conditions and the activity level you expect to encounter and bring extra layers with you in your backpack in case conditions change. Base Layer Materials Polyester, Merino Wool, or Silk but NO COTTON Examples Patagonia Capilene or Smartwool Description Your first layer consists of a lightweight or midweight long- sleeved thermal top and bottom. We recommend materials that wick moisture away from your body like polyester or merino wool. If you cannot wear artificial fibers or wool, silk is an alternate option. Cotton traps moisture and can cause you to chill more rapidly. Zip T-necks are a great option as they allow ventilation. Bring undergarments, sports bras, and/or camisoles in a similar wicking material. Mid Layer Materials Polyester, Merino Wool, Stretch Fleece, Grid Fleece Examples Patagonia R1 Fleece or Rab Power Stretch Description Your second layer consists of a long-sleeved heavyweight (expedition weight) base layer top and bottom or lightweight stretch fleece top and bottom. -
Club Activities
Club Activities EDITEDBY FREDERICKO.JOHNSON A.A.C.. Cascade Section. The Cascade Section had an active year in 1979. Our Activities Committee organized a slide show by the well- known British climber Chris Bonington with over 700 people attending. A scheduled slide and movie presentation by Austrian Peter Habeler unfortunately was cancelled at the last minute owing to his illness. On-going activities during the spring included a continuation of the plan to replace old bolt belay and rappel anchors at Peshastin Pinnacles with new heavy-duty bolts. Peshastin Pinnacles is one of Washington’s best high-angle rock climbing areas and is used heavily in the spring and fall by climbers from the northwestern United States and Canada. Other spring activities included a pot-luck dinner and slides of the American Women’s Himalayan Expedition to Annapurna I by Joan Firey. In November Steve Swenson presented slides of his ascents of the Aiguille du Triolet, Les Droites, and the Grandes Jorasses in the Alps. At the annual banquet on December 7 special recognition was given to sec- tion members Jim Henriot, Lynn Buchanan, Ruth Mendenhall, Howard Stansbury, and Sean Rice for their contributions of time and energy to Club endeavors. The new chairman, John Mendenhall, was introduced, and a program of slides of the alpine-style ascent of Nuptse in the Nepal Himalaya was presented by Georges Bettembourg, followed by the film, Free Climb. Over 90 members and guests were in attendance. The Cascade Section Endowment Fund Committee succeeded in raising more than $5000 during 1979, to bring total donations to more than $12,000 with 42% of the members participating. -
Melt Regimes, Stratigraphy, Flow Dynamics and Glaciochemistry of Three Glaciers in the Alaska Range
Journal of Glaciology, Vol. 58, No. 207, 2012 doi: 10.3189/2012JoG10J238 99 Melt regimes, stratigraphy, flow dynamics and glaciochemistry of three glaciers in the Alaska Range Seth CAMPBELL,1,2 Karl KREUTZ,1 Erich OSTERBERG,3 Steven ARCONE,2 Cameron WAKE,4 Douglas INTRONE,1 Kevin VOLKENING,5 Dominic WINSKI1 1Climate Change Institute and Department of Earth Sciences, University of Maine, Orono, ME, USA E-mail: [email protected] 2US Army Cold Regions Research and Engineering Laboratory, Hanover, NH, USA 3Department of Earth Sciences, Dartmouth College, Hanover, NH, USA 4Complex Systems Research Center, Institute for the Study of Earth, Oceans and Space, University of New Hampshire, Durham, NH, USA 5Department of Chemical and Biological Engineering, Montana State University, Bozeman, MT, USA ABSTRACT. We used ground-penetrating radar (GPR), GPS and glaciochemistry to evaluate melt regimes and ice depths, important variables for mass-balance and ice-volume studies, of Upper Yentna Glacier, Upper Kahiltna Glacier and the Mount Hunter ice divide, Alaska. We show the wet, percolation and dry snow zones located below 2700 m a.s.l., at 2700 to 3900 m a.s.l. and above 3900 m a.s.l., respectively. We successfully imaged glacier ice depths upwards of 480 m using 40–100 MHz GPR frequencies. This depth is nearly double previous depth measurements reached using mid-frequency GPR systems on temperate glaciers. Few Holocene-length climate records are available in Alaska, hence we also assess stratigraphy and flow dynamics at each study site as a potential ice-core location. Ice layers in shallow firn cores and attenuated glaciochemical signals or lacking strata in GPR profiles collected on Upper Yentna Glacier suggest that regions below 2800 m a.s.l.
