One of the most unearthly places in the United States has to be the Craters of the Moon National Monument and Preserve. Idaho is a secretly stunning state that many write off as potatoes (even their vehicle license plate says "Famous Potatoes"). But there are many stunning sights and things to discover in this underrated state, it is full of volcanic landscapes, mountains and forests, hot springs, high desert, and much more.

This volcanic preserve and monument are one of the Lower 48's best-preserved flood basalt areas. It is easily accessed and easily explored. There is no actual accommodation on the site - although there is camping. It is definitely worth a visit - just as Hawaii is worth visiting just for its volcanoes.


About The Caters of the Moon

  • Date: The Monument Was Established In 1924
  • Managed: By Both The National Park Service and The Bureau of Land Management

The Craters of The Moon is a stunning sight encompassing three major lava fields - and around 400 square miles of sagebrush steppe grasslands surrounding those lava fields. The lava fields are all part of the Great Rift of Idaho and have some of the best open rift cracks of anywhere in the world.

  • Size: 1,117 Sq Miles or 2,893 Sq Km

Craters of the Moon is midway from the Idaho capital of Boise and the geological wonderland of Yellowstone National Park. The combined US Highway 20,26-93 cuts through part of the northwestern part of it and provides access to it. Branching off from the highway, there is only one paved road running through it at the northern end.

  • Volcanic Cones: Contains Over 25 Volcanic Cones
  • Lava Flows: 60 Distinct Solidified Lava Flows
  • Age: 15,000 Years To 2,000 Years Ago
  • Elevation: 5,900 Feet or 1,800 Meters Above Sea Level

Some of the older lava flows are being colonized by hardy vegetation, while the newer lava flows remain incredibly hostile and few plants can take root. From the distance, the area can appear black and utterly desolate.

Like other lava flows in the western United States, one can find lava fields, lava tube caves, tree molds (molds left by lava-incinerated trees), and much more.
