As the description says, it appears bottomless, but is actually 325 feet (or so) deep. But Carlsbad Cavern is full of surprises--and stories from its "discovery" by Jim White.

The Bottomless Pit is a big hole in the floor of the Big Room. There is a sign along the walkway that points out the Bottomless Pit. The pit is 140 feet deep.

Told our 9 year old granddaughter we were going to throw her in. Not really bottomless, but so dark down there that it looks like it is. Actually 140 Ft deep. Along the trail around the Big Room.

Available to cavern visitors on the self-guided Big Room Tour, this is at the middle of the walking tour and furthest from your starting point. This formation is unlike many others in the cavern, in that it appears as "just a hole". Remembering how the...More
