Produced by the Craters of the Moon staff. Contents: Exploration and Preservation; From Moonscape to Landscape; Guide and Advisor. Craters of the Moon was so named because at one time, before people had actually gone to the moon, some people thought that the landscape resembled the moon's surface. The name became official with the establishment of the monument in 1924. There are more than 25 cinder cones at Craters of the moon, each one a small volcano. The monument is near the Snake River in Idaho.
