Highlights

Craters embraces an amazing array of volcanic formations - a mix of
spatter cones, cinder cones, fissure vents, raft blocks, and lava tubes
(caves). Lava flows include pahoehoe, and aa (names that originated in
volcano studies on Hawaii), and lava "bombs" come in such
evocatively-named forms as cow dung and breadcrust. Craters is your
one-stop shop for basaltic volcanism! A strange landscape, the
area is considered so lunar-like American astronauts have actually been
trained at this site. (Did anyone think to ask how the places compared,
I wonder?)
The Monument sits on a lava field that is the largest in the United States at 618 square miles (1,600 square kilometers).
You can figure out where the Great Rift lies, by the chain of cinder cones.
The highest cinder cone is Big Cinder Butte which stands more than 700 feet above the surrounding plain.
Craters is home to 300 species of plants, 2,000 insect species, 148 birds, 47 mammals, 8 reptiles, and a lone amphibian, the western toad.
Plants and animals have adapted in unique ways to deal with this environment. A sagebrush sitting unprepossessingly on a lump of lava, might have a tap root going 20 feet down to get at water. Marmots hibernate both summer and winter.
In places, molten lava flows encased standing trees and then hardened, and eventually the wood rotted, resulting in vertical tree molds.
Visitor Information Center. Displays, video, conducted walks, evening programs, and publications for sale, water and comfort station. Phone: 208-527-3257.
Paved roads for vehicles include a 7-mile loop road. Walking trails include disabled access.
Campground is available.
The southern part of the Monument is a wilderness area closed to vehicles.
Getting There
The Monument lies on U.S. Alternate Route 93. You'll find it 29 kilometers southwest of Arco in Butte and Blaine counties. Closest interstate is I-84 to the south.
When to Visit;
Early May until late August (especially late June) when wildflowers transform the harsh landscape.
Winter to ski on the groomed Loop Drive and see a strange landscape of black and white.
Note: Extremes of weather are part and parcel of the Monument. The intense summer sun bakes the black lava, generating air temperatures in the 90's (Fahrenheit). Winds are daily occurrence, especially in the afternoon, and may reach 15 to 30 miles per hour.
And remember rock collecting is not permitted!
