President Calvin Coolidge established Craters of the Moon on May 2,1924, for the purpose of protecting the unusual lava terrain in southern Idaho. This lunar landscape was thought to resemble that of the Moon and was described as, “a weird and scenic landscape peculiar to itself.”

During its 100-year history, the perspectives, values, and significance of Craters of the Moon have varied. Throughout 2024, the park will host multiple activities and events that highlight the “Phases of the Moon” experienced at the park.
