Scientists collecting data on South Cascade Glacier, Washington State. South Cascade Glacier is located in a north-northwest facing valley near the crest of the Cascade Range in northwest Washington state. In 1959 scientists with the USGS began collecting mass balance data on South Cascade Glacier, now one of five "benchmark glaciers" in the US.
