National Park Service, Arizona.
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.
