Another World In the New Mexico desert sits an unremarkable sinkhole. At the bottom of the 90-foot pit, a piece of stainless steel culvert juts up, sealed by an airlock. If you can get the National Park Service to unlock the door, you've reached the Holy Grail of American caving, Lechuguilla Cave.

Indepence Hall Finally Liberated? Even as the streets surrounding Independence Hall (the building where the document declaring US independence from Britain was forged) are finally liberated from barriers erected to prevent terror the historic building has been closed by the National Park Service, who prior to 9/11 couldn't even stop a crazy guy with a hammer.
