Retreating glaciers are an iconic image of climate change;yet not all glaciers in Alaska are actively retreating, and a few glaciers are even advancing. While this contrasting behavior can be misleading for the casual observer, variable responses between glaciers in a changing climate are expected. Glaciers act as conveyor belts that transport snow and ice from high elevations, where it does not melt, down to low elevations, where it does melt. A change in climate can impact the amount of snow and ice that accumulates (accumulation), the way snow and ice melt (ablation), or the conveyor belt (ice dynamics). While these impacts vary with elevation and glacier shape, glacier changes have major implications for downstream...

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...
