Alaska mountains and volcanoes

Alaska's Peaks and Volcanoes

Alaska’s wilderness is shaped by immense tectonic activity, home to some of North America’s most formidable geological features. This selection spans the Alaska Peninsula and the Saint Elias Mountains, featuring Novarupta, the site of the 20th century's largest volcanic eruption, and active stratovolcanoes like Mount Redoubt and Mount Veniaminof. The list also includes Mount Saint Elias, the second-highest peak in both the United States and Canada, and Mount Fairweather, known for its extreme vertical relief near the Pacific Ocean. These sites showcase the state's diverse volcanic systems and massive glaciated summits.
