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. 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. Glaciers store precipitation as ice, transport it away from where it was deposited, then release it as water, sometimes centuries or millennia later. Public domain.) These five glaciers are Lemon Creek Glacier, AK (1953 -Present), South Cascade Glacier, WA (1958 - Present), Gulkana and Wolverine glaciers, AK (1966 - Present), and Sperry Glacier, MT (2005 - Present). The main trunk of the glacier has a southerly aspect, and is fed by four cirques with west, south, and east aspects. South Cascade Glacier in 1991 (USGS) Changes Through Time. In addition to mass-balance measurements, which date to 1958, numerous hydrological investigations have been carried out during the last three decades, and repeated ice-thickness determinations have been made using a variety of techniques.
