Craters of the Moon National Monument and Preserve is perhaps the world’s best example of a lava fields open rift cracks, basaltic lava, and lava tubes.
Named by an early explorer because the lava field’s striking volcanic formations were so unique that he thought it must resemble the surface of the moon, Craters of the Moon still invokes the extraterrestrial imagination of visitors today.
Having last erupted a little over 2000 years ago, the park is extremely fragile as it lies along the Great Rift-- a series of three lava fields. Sagebrush, rabbitbrush, yellow and purple wildflowers, and various other forms of plant life survive in this harsh climate where soil temperatures can reach upwards of 150 degrees in the summer.
Explore the parks developed areas by car and on foot. See spatter cones, cinder cones, lava tubes, caves and host of other lava rock formations.
