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. -

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. -

Expeditionsbericht
Expeditionsbericht Alaska-Range, Kahiltna Basecamp 22. April bis 20. Mai 2016 Teilnehmer: Julian Bückers, Michael Dürr, Christoph Hummel, Tobias Karpinski Blick vom P 13790 zum Mount Foraker. Der Rücken, der von rechts auf den Gipfel führt, ist der oberste Teil der Sultana Ridge, dem einfachsten Weg auf diesen Berg. Gebiets-Recherche: Wir hatten uns für eine Expedition in die Ruth-Gorge vorbereitet: Für Topos und Routeninformationen war vor allem die Homepage des American Alpine Journal nützlich, ebenso die Alpenvereinsbibliothek auf der Praterinsel in München, wo eine vollständige Sammlung aller Ausgaben des AAJ vorliegt. Anreise: Die Anreise nach Talkeetna, von wo aus man alle Ziele in der Alaska Range per Luft-Taxi erreicht, ist problemlos. Nach der Landung in Anchorage tätigten wir alle wichtigen Einkäufe in Anchorage. Wir waren für Lebensmittel und Basislagerausstattung in zwei Geschäften: Im riesigen Supermarkt Fred Meyer (1000 E Northern Lights Blvd, Anchorage, AK 99508) und im nahen REI Bergsportgeschäft (1200 W Northern Lights Blvd, Anchorage, AK 99503, United States). Praktisch war, dass man spezielle Biwaknahrung, Gas, etc. bei REI (https://www.rei.com) vorbestellen kann - diese Dinge lagen dann abholbereit verpackt für uns im Laden in Anchorage bereit. Auf der gegenüberliegenden Straßenseite befindet sich das noch mehr für Alpinismus ausgelegte Bergsportfachgeschäft AMH (https://www.alaskamountaineering.com). Nach einer Nacht in Anchorage ließen wir uns von Talkeetna Taxi (http://talkeetnataxi.com/) nach Talkeetna fahren. Das Taxi sollte man ein paar Tage vorher bestellen, die Kosten belaufen sich auf 250 - 300 US-Dollar. In Talkeetna unterhält Talkeetna Air Taxi ein sogenanntes "Bunkhouse", in dem Kunden bis zu ihrem Abflug und nach der Rückkehr kostenlos übernachten können. -
Five-Day Glacier II Seminar
Shasta Mountain Guides Glacier Seminar II Glacier Travel and Crevasse Rescue Hotlum Glacier Mount Shasta Below is a detailed itinerary for the 5-day Glacier II Seminar. Please see our frequently asked questions page, or contact the office for more details about your climb. Also, please keep in mind that the projected itinerary may vary due to weather and trail conditions. The scheduled route is the Hotlum Glacier accessed from the Brewer Creek Trailhead. Day 1 Meet and Course Start: 9:00 am Meet guides and group at the SMG Shop 230 N. Mt. Shasta Blvd. Please be punctual to allow enough time for gear rentals, packing, and a group briefing with your guides. Your guides will do a thorough gear check and pass out group gear before packing your backpacks. 10:00-11:30am Drive to the Brewer Creek trail head (7200’) for a group briefing and start the approach to base camp (10,200’). The drive is approximately 1 hour on dirt roads; we do not provide transportation but encourage carpooling. 11:30-4:30pm Hike to base camp. Depending on weather and trail conditions, this approach to base camp may take anywhere from 4 to 6 hours, it is mostly cross country hiking on dry rugged terrain Distance hiking: 3 miles, 3,000’ elevation gain 4:30pm-8:00pm At base camp the group will set up camp, enjoy dinner prepared by your guides, and pack for the following day of skills instruction. There will be plenty of time for questions and answers, and possibly some appropriate skill sessions. -

Thus, we’ve teamed up with the American Breast Cancer Foundation, an organization that is doing their part to save our world, one breast at a time, in order to do our part, in hopes of becoming role models and encouraging the rest of the world to do their part too. So here’s our plan: We are going to climb Denali (Mount McKinley) via the West Buttress route in June of 2006. -

Alaska followed close behind with 111 climbers. There were 87 climbers from Washington and 72 from California. • International climbers: 420 (37% of total) 51 foreign nations were represented on Denali in 2018. Of the international climbers, Poland generated the highest number of climbers with 47. Canada was next with 42. Australia was suprisingly well-represented on Denali this season, with 28 climbers.
