Mass Balance Factsheet for the South Cascade Glacier, Pacific Coast Range
South Cascade Glacier is a temperate mountain glacier located in the North Cascade Mountains, Alaska. This glacier has been classified as one of the ‘reference glaciers’ by the World Glacier Monitoring Service because it has received continuous long-term observations dating back to the year 1952/53. Year-to-year variations in snow accumulation on the glacier are largely attributable to the regional maritime climate and fluctuating climate conditions of the North Pacific Ocean. Long-term average precipitation is about 4500 mm and most of that falls as snow during October through May. Average annual air temperature at 1900 m altitude (the approximate ELA) was estimated to be 1.6 °C during 2000-2009 (WGMS, 2011).
