Lunar Crater Volcanic Field

This otherworldly bowl-shaped hole is nearly 4,000 feet across and 430 feet deep, and was formed two million years ago when lava bubbled along a fault line. To get there, turn right onto US-6 east at the Warm Springs junction. After 27.8 miles, turn right at the “Lunar Crater” sign on your right, and follow it 6.4 miles to the crater.
