Nature
Susitna Glacier is an alpine, or valley, glacier in Alaska’s Alaska Range. It is significant both as a mountain glacier and because it lies across a seismically active area. Its importance increased during the 7.9-magnitude Denali earthquake in November 2002, when the quake began with thrust movement on what had not previously been recognized as the Susitna Glacier fault. That event tied the glacier’s name to one of the most powerful earthquakes recorded in the region.
