Moaning Caverns is home to the largest single cave chamber in California. The massive room reaches over 180 feet before funneling into smaller passageways. With a 20-30 foot thick ceiling, the open area inside the chamber is, in fact, tall enough to hold the Statue of Liberty (pedestal excluded). There is only one natural entrance into the chamber in the form of a 30-foot vertical chimney dropping into the center of the room. This does make commercial entry a little difficult so dynamite was used in the mid 1800s to expand a natural crack in the ground wide enough for stairs to be built down. The narrow wooden staircase ends at a flat platform 65 feet underground. From there, a ten story spiral staircase leads down to a second platform at the base of the chamber.
