South Cascade Glacier,
Vertical air photo of South Cascade Glacier and basin. The thin veneer of snow remaining on the glacier at this time is rapidly disappearing. The transient accumulation-area ratio is 0.40, which can be compared with the values of approximately 0.30 on September 30, 1966, and 0.15 on October 16, 1966, the end of the balance year. Although little snow remains on the glacier, accumulation patterns are still obvious in this photo. The strong influence of the prevailing western storm wind is indicated by drift patterns and by the predominance of snow remaining on the western side of the glacier (north to top of photo). Chelan and Skagit Counties, Washington. September 22, 1966. (Aerial view) Published as figure 7 in...

Album caption: South Cascade Glacier, North Cascade Range. Photo no. 8 was taken presumably in the autumn of 1928. Photo no. 9 was taken September 23, 1965. Note that the transient snowline is very near the same position in 1965 as in 1928, so that accumulation areas for both years are similar in size. The higher altitude glaciers and perennial snowfields shown in these photos have changed very little in size. However, because the exposed ice areas below the equilibrium line were much larger in 1928, ice loss would be much greater in 1928 than in 1965 even with similar meteorological conditions. Most of the mass loss in the 1928-65 interval occurred below the present equilibrium line. Chelan and Skagit Counties,...

Scanned field notebooks from a USGS Benchmark Glacier: South Cascade Glacier, Washington,1957 - 2022
This data release is a collection of data and field notes documenting snow and ice changes on South Cascade Glacier, Washington, USA. The field records relate to glaciological research and reflect evolving interpretations of glacier mass balance, climatology, hydrology, and other glacier-related research conducted at the site between 1957 to 2022 in association with the USGS Benchmark Glacier Project. Notebooks have been scanned in their entirety in PDF format. The USGS Benchmark Glacier Project has monitored targeted mountain glaciers across North America since research was initiated at South Cascade Glacier in 1957. Data from the five benchmark glaciers located in Alaska, Washington, and Montana, provide continental-scale...

Since the late 1950s, the USGS has maintained a long-term glacier mass-balance program at three North American glaciers. 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. The Juneau Icefield Research Program has measured surface mass balance on Lemon Creek and Taku Glacier since the mid-1940s, with USGS providing complimentary seasonal measurements of Lemon Creek beginning in 2014 (JIRP; Pelto and others, 2013). Direct field measurements of point glaciological data are combined with weather and geodetic data to estimate the seasonal and annual mass balance at each glacier in both a conventional and reference surface...
