Lexington Arch in the south end of Great Basin National Park in Nevada



Lexington Arch is a limestone arch in the southern part of Great Basin National Park in Nevada.  To get here you have to drive on dirt roads and then hike about a mile and a half on a rugged trail.  The fact that this arch is composed of limestone is very noteworthy, since most of the arches in the West occur in sandstone.  The fact that this rock span occurs in limestone may mean that it was once part of a cave that has eroded away.  Or it may be that the stream that carved Lexington Canyon carved this span when the canyon was much shallower, in which case this arch would actually be a natural bridge.

Remember it's not just a picture, it's a story!
