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.
