Part of the Arnold lava tube system, and historically a genuine ice cave: Bend cut and hauled ice out of it in the early 1900s. The ice has thinned dramatically over the last century, and the cave is now CLOSED to entry to protect a significant bat hibernaculum. Included because the geology and the ice-harvesting history are real and the surface can still be visited, but do not go in.
