Melt Regimes, Stratigraphy, Flow Dynamics and Glaciochemistry of Three Glaciers in the Alaska Range

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).

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. -

Radio Control Tower, Southwest Buttress, It's Included
AAC Publications Radio Control Tower, southwest buttress, It’s Included Alaska, Central Alaska Range In June, Alan Rousseau and I flew into the Southeast Fork of the Kahiltna Glacier between guiding trips on Denali to see what we could get done. With huge amounts of snowfall and warming temps, we ruled out all routes with snow above them. We decided to get a bit creative. This led us up a new route on the very rocky southwest buttress of Radio Control Tower (8,670’), which is located just east of Kahiltna Base Camp. The route was an interesting outing with some harder pitches and lots of exploration required to reach the top of the buttress: It’s Included (1,000’, 5.10+ AI3 M7). – Mark Pugliese Editor’s note: Previously unreported, in May 2013, Alan Rousseau and Aaron Kurland made the first recorded ascent of the west face of Radio Control Tower, climbing a prominent gully and snow-ramp system just left of the southwest buttress. They called the seven-pitch climb Spindrift Couloir (1,000’, AI3 M5). Given the proximity of Radio Control Tower to the Kahiltna Base Camp it’s possible other routes have gone unreported. Images The southwest buttress of Radio Control Tower showing the new route It’s Included (1,000’, 5.10+ AI3 M7).

The goal of the score is to encourage cost- effective investment in energy efficiency improvements for these types of buildings. The system, known as the Building Energy Asset Score, will allow building owners and managers to compare their building infrastructure against peers and track energy efficiency impacts of building upgrades over time. The system will also help other building stakeholders (e.g., building investors, tenants, financiers, and appraisers) understand the relative efficiency of different buildings in a way that is independent from operations and occupancy. Prior to developing the Asset Score, DOE performed a market study1 to ensure that the effort would help address market needs and fill identified gaps. In 2012, DOE began initial pilot testing of the Asset Score. In 2013, DOE continued to assess the Asset Score through additional pilot testing and a variety of technical evaluations and performance analyses. -
