Overview:

Diamond Craters, an Outstanding Natural Area of 17,000 acres (23 square miles), has some of the most diverse basaltic volcanic features in the nation clustered within a small, accessible area. The area displays an entire range of eruptions possible in basaltic volcanism. It was formed sometime in the past 25,000 years and now resembles a thin, rocky pancake with a few bumps. Features identifiable at the Outstanding Natural Area include craters and vents, cinder cones, spatter cones, lava tubes, driblet spires, a graben, and a water-filled maar.

Know Before You Go:

• It took thousands of years of volcanic activity to form Diamond Craters, but only a few seconds can damage its features. Help BLM protect this area. Please do not destroy or collect plants, animals or rocks.
• There are no restroom facilities or other amenities. Bring your own water and shelter and follow Leave No Trace principles: pack it in, pack it out.
• Keep your vehicle on hard-packed road surfaces and obvious parking areas.

Point of Interest:

Located in southeast Oregon's high desert country, Diamond Craters is really unlike any other place in North America.
