It adds a whole new dimension to “bringing down the house”…
This is the entrance chamber of Indian Tunnel, in Craters of the Moon. Indian Tunnel is a lava tube, about 800 feet long. Various portions of the tube have collapsed over the centuries, letting in daylight and making this tunnel the easiest one to hike in the National Monument.
At the back of the chamber you can see light from another hole in the roof, signaling the way to more chambers and finally the exit.
