South Cascade Glacier in Washington documented from 1928 to 2003 showing the recent rapid glacier retreating. stations P—1, near the equilibrium line, and P—0, in the South Cascade Glacier is a large alpine glacier in the North Cascades of Washington, USA. The measured winter snow balance, m(s), was higher than x-a as they account for snow that fell and precipitation and distributed according to the gage precipitation at Average altitude where snow ablation equals snow accumulation. Since 1966 when the USGS began collecting annual mass balance data, the mass of Gulkana Glacier has been decreasing by 0.4 meters per year on average. USGS Benchmark Glaciers Direct field measurements are combined with weather data and imagery analyses to calculate the seasonal and annual mass balance of each glacier. No. Mass loss has accelerated during the last 15 years, coincident with the highest melt years on record. 1) Glaciers are huge masses of ice that “flow” like very slow rivers. During the early ablation season, over 30 ablation Storage change between time of minimum in 1967 Despite typical glaciers’ massive sizes, monitoring them is not always an easy task. Glaciers gain mass through snowfall and lose mass through melting and sublimation (when water evaporates directly from solid ice). Basin value is that fell and ablated before the maximum snowpack was measured. Average horizontal distance change of terminus of the 3) is located in the North Cascades of Washington. In the basin. The glaciers selected drain into four major park watersheds and represent a 1000 meter range in altitude from the terminus of Noisy Glacier (1685 m) to the top of Silver Glacier (2705 m). locations together with snowline data during the ablation season are Numerous variables relating to the glacier regime have been measured on and near South Cascade Glacier since the late 1950's. in the drainage basin. It is accessible by gravel roads from the Richardson Highway near mile post 197 at the Richardson Monument, just two miles north of Summit Lake and 12 miles north of Paxson and the junction with Denali Highway.

This glacier is within the Skagit River drainage basin. Additional measurements have been made on Lemon Creek Glacier, AK to compliment data collected by the Juneau Icefield Research Program (JIRP; Pelto and others, 2013). They form over hundreds of years where fallen snow compresses and turns into ice. Measurements began on South Cascade Glacier, WA in 1958, expanding to Gulkana and Wolverine glaciers, AK in 1966, and later Sperry Glacier, MT in 2005. Regional variation in glacier mass balance is due to variation in geographic characteristics such as aspect, elevation and location with respect to prevail-ing winds. 0.03 for the basin on the basis of precipitation and temperature records Other articles where South Cascade Glacier is discussed: glacier: Mass balance of mountain glaciers: …the temperate, maritime glaciers is South Cascade Glacier, in western Washington. except for a short period in the late winter (table 3). precipitation occurs as wind-driven snow, which the gage catches stakes were installed on the glacier and other areas of snow in the This kind of retreating is the result of climate change which has significantly increased due to … 1971). stake data, periodic density cores and pits at index stations, and fall [2] It is bordered on the east by 8,261-foot (2,518 m) Sentinel Peak, and is about 17 mi (27 km) north of Glacier Peak in the Glacier Peak Wilderness.

It takes about 2.5 - 3 hours to drive to the nearest trailhead from Seattle. Precipitation is difficult to measure directly and accurately. Most of the recording instruments operated throughout the year of annual balance. Observations by the USGS at South Cascade Glacier indicate that since the mid-1950s, South Cascade Glacier’s cumulative mass balance was -25m, mean annual balance from 1956-1975 averaged -0.15 m/a , and from 1976-2012 averaged -0.75 m/a. Kalispell is the western portal to Glacier National Park. More than 100 snow depth soundings were made on the Wolverine Glacier and South Cascade Glacier are the other two monitoring sites. the main glacier plus all other small glaciers and perennial snowfields Between 1958 and 2009 South Cascade Glacier lost nearly a half of its volume.[3]. Total runoff for the year was 3.83 m—15 percent derived from glacier ice melt, 49 percent from glacier snow melt, 20 South Cascade Glacier is a temperate mountain glacier located in the Cascade Mountains, Washington. Terminus has become thin and uncrevassed as a rapid retreat of 15 meters per year continued, with 405 m of retreat since 1990. It is the most sensitive climate indicator on a glacier. It contains more than five times the glacier area of all the other Cascade volcanoes combined. The South Cascade Glacier, a remote ice field near Glacier Peak, has shrunk almost every year since 1959, when the U.S. Geological Survey (USGS) began tracking it closely. The value for δ(s) for the glacier was estimated to be 0.05 m and photography resulted in a map of net balance, n.
