When describing glaciers in Wrangell St. Elias National Park and Preserve, superlatives are evident. Within park boundaries exists the nation's largest glacial system, with glaciers covering 35 percent of the parklands. In summer, these glaciers contribute a significant portion of the rivers' high runoff and heavy sediment load. During the winter, glacial melt reduces and many rivers run with clear water.
