"Craters of the Moon National Monument and Preserve is a United States National Monument in the Snake River Plain of Central Idaho. The park was created to protect a vast landscape of lava flows with scattered islands of cinder cones and sagebrush. Starting 15,000 years ago, the landscape was created by molten lava flows. While the park's landscape varies tremendously from the celestial body after which it was named, it was nevertheless visited in 1969 by Apollo 14 astronauts Alan Shepard, Edgar Mitchell, Joe Engle and Eugene Cernan who explored the lava landscape in order to learn the basics of volcanic geology in preparation for future trips to the moon."
When I drove through there last month on U.S. highway 20 it was more dynamic than usual. Below is a short movie of my time there. Best when your sound is up high.
