Glaciers are sensitive to climate change; records of their past fluctuations can improve predictions of glacier responses to future climate change and generate valuable terrestrial paleoclimate data. Most glaciers around the world are small vestiges of lager valley glacier and ice cap complexes that existed during the last Ice Age. Today, these features are melting in response to anthropogenic climate change. Despite their small size, modern glaciers play an outsized geomorphic and ecological role in alpine landscapes. Thus, understanding how these glaciers reacted to past climate changes and how they will react to future climate changes is imperative for understanding the past evolution and future “fate” of alpine catchments in the western US and elsewhere.
