Diamond Craters, an Outstanding Natural Area of 17,000 acres, has some of the most diverse basaltic volcanic features in the nation clustered within a small, accessible area. Located in the high desert country about 55 miles southeast of Burns, Oregon, Diamond Craters is really unlike any other place in North America. Thats the opinion held by scores of scientists and educators who have visited and studied the area. It has the best and most diverse basaltic volcanic features in the United States and all within a comparatively small and accessible area, one geologist summarized. There is only a 550 foot range from the lowest to highest point with elevations ranging from 4,150 to 4,700 feet above sea level. Named for Mace McCoys diamond brand, Diamond Craters displays an entire range of eruptions possible in basaltic volcanism. This volcanic area was formed some time in the past 25,000 years, with some of the eruptions taking place as late as 1,000 years ago, 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 water-filled maar. Its an isolated place and some precautions should be taken when traveling in the area. First, Diamond Craters has no tourist facilities. The nearest places where fuel is sold are Diamond and Frenchglen. Keep your vehicle on hard-packed road surfaces and obvious parking areas. Certain roads and trails are closed for rehabilitation. Be careful or you might spend time stuck in loose cinder, volcanic ash or clay. If you go hiking, carry drinking water. Watch out for rattlesnakes. If you come upon one, stay calm and allow the snake to glide away. It took thousands of years of volcanic activity to form Diamond Craters, but requires only a few seconds of carelessness or thoughtlessness to destroy its features. Help BLM protect and preserve Diamond Craters. Please do not destroy or collect plants, animals or rocks.
