Craters of the Moon Lava Field – Idaho, USA

Protected in 1924 as a US National Monument. The Monument received an International Dark Sky Park designation in 2017

Occupying an area of 400 square miles and bordering the Snake River Plain, Craters of the Moon Lava Field is the largest Holocene-aged basaltic lava field in the continental US and is one of the best-preserved flood basalt flows in the US.

Between 6 million and 15,000 years ago eruptions first produced 4,000-ft. thickness of basalt flows.  Sporadic eruptions continued between 15,000 and 2,000 years ago that now form present day surface of the Craters of the Moon Lava Field. In 1969, Apollo 14 astronauts prepared for their trip to the moon by spending time in the lava fields. NASA research continues at Craters of the Moon today.
