Hawaii is one of America’s hot spots, but so are the frozen summits of the Aleutian Islands, and high, alpine parklands in the Pacific Northwest. Yellowstone’s famous geysers and hot springs and the largest rapid in Arizona’s Grand Canyon share something in common: volcanism.

High, violent volcanoes punctuate the Pacific Northwest’s Cascade Mountains. Life is returning to the base of Mt. St. Helens, but its 1980 eruption still scars the land. Visit the spectacular, towering giants along America’s ring of fire: Mt. Rainier, Mt. Hood and Mt. Shasta. Hike to the desolate, sulfur-scarred landscape of Mt. Lassen’s “Bumpass Hell,” where the inferno that powered its last eruption still lurks below the surface.

The tropical beauty of the Hawaiian Islands belies their violent origin. Walk perilously close to the edge of continuing lava flows on the big island of Hawaii. Peer into the 2000-foot indigo blue of

, the clearest waters in the world. Journey to Yellowstone’s geysers, hot springs, and colorful thermal pools, and right into one of the world’s few super volcanoes.

Discover how an eruption around 1100 A.D. changed life in an unexpected way for early Pueblo Indians in Arizona. Some of the world’s grandest scenery is to be found at America’s Hot Spots, where even the land is alive.
