Spatter Cones Trail is a very easy hike in Craters of the Moon National Monument near Twin Falls, Idaho. The monument says "like Yellowstone's Old Faithful, the spatter cone chain at Craters of the Moon best symbolizes the essence of this special place. Created during a dwindling stage of an eruption, the spatter cones formed as hot lumps of lava were thrown a short distance into the air only to fall back to earth around a small central vent. As the still molten blobs landed on top of each other, they cooled and adhered to nearby pieces to form the walls of what could be considered a mini-volcano." There is camping available in Craters of the Moon National Monument.
In the summer of 1969, Apollo 14 astronauts including Alan Shepard, Edgar Mitchell, Joe Engle, and Eugene Cernan trained in Craters of the Moon National Monument. They explored the lava landscape and learned the basics of volcanic geology in preparation for future trips to the moon.
