The monument preserves 83 square miles of it, and features more than 20 volcanic cones including outstanding examples of spatter cones. The more than 60 different lava flows on the surface range in age from 15,000 to just 2,000 years old. Surprisingly, this seemingly desolate landscape is home to more than 350 species of plants, 160 species of birds, and 43 mammals.
