Uhehebe Crater: Volcano!
Death Valley National Park, California
The view into Uhehebe Crater is perfectly fine from its rim-side parking area, but the adventurous can walk 600 feet down to its floor or brave the wind gusts and take a trail 1.5 miles around the rim. The crater was not created by molten lava or a killer meteor, but by a big bubble of superheated steam that exploded just beneath the surface. Death Valley's extreme lack of water has preserved the hole pretty much as it was just after the Earth belched 4,000 years ago. Local Indians called the crater "Coyote's Basket."
