Ubehebe Crater
At 500 feet deep and ½ mile across, this crater resulted from underground steam and gas explosions, some as recently as 300 years ago. Volcanic ash spreads out over most of the area, and the cinders lie as deep as 150 feet near the crater's rim. Trek down to the crater's floor or walk around the 2-mile rim counterclockwise to avoid the steep uphill climb. Either way, you need about an hour and will be treated to fantastic views. The hike from the floor can be strenuous, especially because of loose terrain.
