Quick Summary

Nisqually Glacier is one of the glaciers surrounding Mount Rainier, the highest peak in Washington state and the Cascade Range. This glacier, along with others, forms the largest single-mountain glacier system in the United States outside of Alaska. The Nisqually Glacier's retreat and advance over the past 150 years have been valuable for scientists studying patterns in Earth's climate. Glaciers respond to climate change sequentially; changes in the local climate affect the glacier's mass and heat exchange, which in turn influences its net mass balance. This balance determines whether the glacier advances or retreats.12

Mount Rainier
…from the broad summit, including Nisqually Glacier, whose retreat and advance over the last 150 years has helped scientists determine patterns in Earth’s climate. The mountain has three major peaks: Liberty Cap, Point Success, and Columbia Crest (the latter is the summit, located on the rim of the caldera). Rainier…
