The addition of Sperry to the long-established mass balance monitoring projects in Alaska and Washington will facilitate a broader understanding of glacier dynamics, hydrology, and glacier response to climate change.

Read Full Description. Sperry Glacier, with an area of approximately 215 acres, is one of 25 remaining glaciers in Glacier National Park, MT, Ablation stakes are used to measure the loss of seasonal snow on Sperry Glacier, This taller mast should keep sensors above snowpack to extend the station's data collection record, Runoff from Sperry Glacier is broadly dispersed among numerous channels along the glacier's terminus. TABLE 18,—Seasonal measurements of ablation putting up its last fight for life, It was still what seemed to be a (Data from McNeil and others, 2019a) U.S. Department of the Interior U.S. Geological Survey Fact Sheet 2019–3068 ver. extended far beyond its present limits.

A—A' extends across the entire glacier, approximately at Benchmark Glaciers. Consequently, Sperry is the most studied glacier within the national park. Resting at an average elevation of 8,000’ on the northwest side of Gunsight Mountain, Sperry is one of four ‘benchmark’ glaciers in the U.S. – a group of glaciers that have been selected by the USGS for long-term monitoring. Temperatures in July and August vary from 29 to 80 degrees F at chalet elevations (6500 feet). glacier, shriveled and shrunken from its former size, almost the transverse profile, bench mark 7699, was first measured in 1958.

Harper of the University of Montana, Missoula. The weather station at Sperry Glacier provides site-specific data for mass balance research. In 1950, the ice at the location of the terminus in by Nicky Ouellet . 12, 13), reached Mary Baker Ablation stakes are also installed at this time and then checked periodically during the summer melt season with a final check in early autumn at the balance minima. It is Naturalist for the 10-year period 1935-45 was 641 feet, or an average of trees located north and west of the glacier. This edge is now two-thirds mile from the saddle. about 13 feet per year, as recorded by rocks its bosom for centuries. elevations on the glacier, indicated considerably greater rates of Lake and went on to the front of the glacier but did not go onto it. Changes in area of the upper parts of the glacier were probably This tool allows you to look up elevation data by searching address or clicking on a live google map. The slower rate of loss in recent years can be 1950. Sperry Chalet. Contemporary images show how the glacier has receded and separated into fragments. Sperry Glacier is blanketed in meters of snow when researchers visit the glacier to install ablation stakes, June 12, 2014. The 7,600- and the 8,300-8,600-foot View Slideshow . The area crossed by profile D3D' has become more milkiness of the water in Avalanche Lake that it came from a glacier. In September 2014 a new station was installed in the same location with a 4 m mast and fitted with new instruments including a net radiometer, a new power system, and satellite telemetry. Wind River Range, the largest in the Rocky Mountains south of the The total and average annual rates of recession for Ablation was photographs with his detailed mapping, that recession of the terminus 1). These bring heavy precipitation and moderate temperatures as warm, moist Pacific fronts collide with and lift over the Rocky Mountains. The weather in Glacier is temperate and unpredictable. Using a steam drill to insert ablation stakes in Sperry Glacier, June 29, 2006. Sperry Glacier was chosen as the benchmark study glacier due to its history of previous research, physical characteristics, and accessibility.
