Period of Record: October 1966 to September 1978, October 1989 to September 1993, October 1994 to current year, and annual maximums, water years 1984-85. Large fluctuations result from ice melt and alternate damming and storage release during melt season. In 1966 scientists with the USGS began collecting mass balance data on Gulkana Glacier, one of two "benchmark glaciers" in Alaska. The main trunk of the glacier has a southerly aspect, and is fed by four cirques with west, south, and east aspects. ft. single-family home is a 3 bed, 3.0 bath property.

Gulkana Glacier is a glacier that flows from the ice fields of the south flank of the eastern Alaska Range. The Gulkana Glacier, located in the eastern Alaska Range, is one of two Alaska glaciers that have been tracked by USGS for nearly 50 years. Measurements began on Gulkana Glacier during the early 1960's with the University of Alaska Gulkana Glacier Project (Péwé and Reger, 1983). To increase the spatial distribution, two additional weather stations were placed higher in the basin in 2012 allowing researchers to directly measure lapse rates in each basin.

If you’re driving south, you’ll see a gravel road on the east side of the highway (if you see the Richardson Monument, you’ve gone too far). The climate is continental, characterized by a large range in temperatures, and irregular, lighter precipitation as compared to more coastal areas. The typical minimum winter under-ice discharge is about 0.04 m3/s, which is about three to four times the average contribution from the combined geothermal melt of the bed of the glacier and melting caused by the loss of potential energy from ice motion. This A-frame hut is located at 4800 feet and requires an understanding of glacier conditions to reach it. A dramatic example of glacier retreat: top photograph shows lower Gulkana Glacier on July 1910; bottom photograph shows view from same location on July 1952.

Gulkana Glacier 1967 (USGS) Gulkana Glacier is a branched valley glacier in interior Alaska on the south-facing flank of the eastern Alaska Range. Gulkana River known in local as Gulkana River, is a Stream and is located in the state of Alaska, United States and the Time Zone is America/Anchorage. If you have insights you would like to share we welcome those as well. The glaciers are distributed in different climate regimes to better define glacier response to changes in climate forcing. Balance studies were relatively intensive until the mid-1970's, after which spatial sampling was reduced to three sites used as indices for mass balance. Snowfall is the dominant form of precipitation and usually accumulates on the glacier from September through mid-June. The addition and upgrading of sensors over the years have included measurement of precipitation (Sutron gauge) and new stations to directly measure lapse rates in each basin. Nunatak is on bedrock between the main trunk and a western cirque at 1725 m. The sensors installed measure: Ridge-top weather station (Latitude 63°18'N, Longitude 145°24'W). Gulkana Glacier is one of three detailed long-term glacier monitoring sites run by the USGS in a study on climate change and glacier-related hydrologic processes. The glacier, looming 1300 meters in elevation, is located along the south flank of the eastern Alaska Range. Gulkana Glacier is located along the south flank of the eastern Alaska Range. Field visits to measure and maintain stakes at the three index sites are made each spring, at the onset of the melt season, and again in early autumn, near its completion. Gulkana River Trail is a 0.5 mile lightly trafficked out and back trail located near Glennallen, Alaska that features a river and is rated as moderate. Access all the data here. ft. house located at 16 Gulkana Glacier Ln, Martinsburg, WV 25403 sold for $220,000 on Jan 30, 2020. These mountains are generally high, having individual peaks up to 3,000 m in altitude, and are very rugged. The main trunk of the glacier has a southerly aspect, and is fed by four cirques with west, south, and east aspects. The station is slightly lower than the glacier's average equilibrium line altitude (ELA) and approximately 300 m from the east edge of the glacier. The channel is subject to frequent changes during high flows. The average ELA is near 1,735m which is consistent with a continental mountain climate. Location. Density of the material gained or lost is measured with a snow-pit or core. Daily values of discharge are available online and published annually in the USGS Water-Data report series. The creek bed contains gravel and boulders of various sizes, typical of a glacial moraine. For several years this project measured the energy budget, mass balance, meteorology, foliation, flow, and glacier bottom topography (from gravity anomalies) at Gulkana Glacier. Gulkana Glacier is located about 175 miles southeast of Fairbanks, so the day began at 7:00 AM in order to have as much time as possible on the glacier. Repeated point measurements at established index sites, in conjunction with local meteorology and runoff data, are used to estimate glacier-wide mass balances. The stations are telemetered for real time data acquisition.

By collecting data near the balance maxima and minima direct measurements closely reflect maximum winter accumulation and the annual balances at each location. ft. single-family home is a 3 bed, 3.0 bath property. The study monitors climate, glacial movement, glacial runoff, glacier mass-balance, and stream runoff. Data from two glaciers located in climatically distinct basins form the basis of this project in Alaska: Gulkana Glacier, a continental glacier located in the Alaska Range, and Wolverine Glacier, a maritime glacier located in the Kenai Mountains. In addition, the motion of the ice has slowed, which has resulted in glacier retreat. Meteorological observations began in 1967 with installation of temperature and precipitation instruments near the moraine weather station.
