Glaciers and glacier systems are dominant and dynamic physical features of two of the three parks (Denali, Wrangell-St. Elias) in the Central Alaska Network and are a driver of landform and ecosystem change in them. Glaciers are inextricably tied to climate and the hydrological cycle. Because glacier systems are regulated solely by climate fluctuations, they provide a reliable record of long-term climate change that has already occurred. Upper elevation climate is nearly impossible to measure directly and can be well represented by glacier dynamics. Glaciers provide significant hydrologic base flow to major rivers in Central Alaska national parks. Approach In Denali, mass balance has been measured twice annually on Traleika and Kahiltna glaciers since 1991. Terminus mapping is completed for the park using aerial and/or satellite imagery every decade or so. In addition, repeated measurements are taken on several focus glaciers throughout the park to measure changes in surface elevation. NPS does not conduct routine glacial measurements in Wrangell-St. Elias. Instead, extensive work by partner agencies and outside researchers is used to track the status and trends of the park’s glaciers. USGS maintains two long-term monitoring sites on the Gulkana and Wolverine glaciers. In 2013, mass balance and surface elevation data was analyized for a ~60 year period. Future plans include adding mass balance index sites within the park.
