Sunset Crater Volcano National Monument

The lava flow lies on the land like a dream, a wonderland of rock. A thousand years ago the ground was torn open and lava erupted into the sky, forever changing the landscape and the lives of the people who lived here. A thousand years later, trees and flowers grow among the rocks, and people visit the lava flow to see and remember the most recent volcanic eruption in Arizona.

Sunset Crater Volcano

Sunset Crater Volcano is named for the color of the rusty red cinders near its peak.
