Program Overview/Why Study Gulkana Glacier?

The U.S. Geological Survey (USGS) operates a long-term program to monitor climate, glacier motion, glacier mass balance, and stream runoff. The data collected are used to understand glacier-related hydrologic processes and improve the quantitative prediction of water resources, glacier-related hazards, and the consequences of climate change (Fountain and others, 1997). The approach has been to establish long-term mass balance monitoring programs at three widely spaced glacier basins in the United States that clearly sample different climate-glacier-runoff regimes. Gulkana Glacier is one of these three long-term, high quality mass balance monitoring sites operated by the USGS. The other monitoring sites are Wolverine Glacier in south-central Alaska and South Cascade Glacier in Washington.
