Ubehebe Crater is less than 10,000 years old, a relatively recent (in geologic terms) volcanic crater. We hiked all the way around the rim of this 500 foot deep, 1/2 mile diameter crater. Along the way we also had a nice overlook of Little Hebe Crater, a younger crater, which is just south of this crater. There is a trail to the floor of the crater but we didn't go there. It wasn't because it was unsafe, we were limited in time and decided to circle the crater rather than go into it. It was a windy cool day up on the rim of the crater at 2600 feet.
