Alaska's 'El Capitan' offers view into 420 million years of natural history

Hopping into a hole in the ground isn’t everyone’s idea of a good time. But for some, it’s an out-of-this-world — or under-this-world — experience. Only one natural cavern in Alaska is open to the public on a regular basis. It’s El Capitan Cave in the remote north of Southeast’s Prince of Wales Island.
