Ready to add another world record to Idaho’s rap sheet? Stretching over 4,000 square miles, Craters of the Moon National Monument and Preserve is an unearthly, apocalyptic landscape of volcanic cones, craters, caverns, and fissures, all strikingly beautiful in their rocky glory, in addition to protected steppe desert. But this eerily beautiful expanse is also home to more than a few surprises, including this one: a plunging crater of undetermined depth, roughly the size of a football field, sitting just outside of the preserve on the King’s Bowl lava field. And it’s rather spectacular.
Yet another one of Idaho's glorious "middle of nowhere" surprises, Craters of the Moon is a treasured--abeit unearthly--moonlike landscape tucked away near Arco.
Surprisingly vast and like something out of Lord of the Rings, pioneer explorers through the area understandably took the long way around to avoid this basaltic, volcanic landscape.
"Miles and miles of ghastly ragged lava rolled away toward the grey expanse of sage. In color it was blue, black, red, like rusty iron, seamed and fissured, caked and broken, a rough-tile surfaced place over which travel was almost impossible." -Zane Grey, Forlorn River, 1926

But take a closer look, and you'll find some incredible beauty here.
As recently as 1600 years ago, volcanic fire spewed out of this unique line of cracks and fissures in the earth, forming Craters of the Moon as we know it today. At points, you can see the bottom of the rift while at others, the bottom is unfathomable.
