A Natural Bridge on the Moon
The most extraordinary collapse pit found in LROC images is this one in King crater. What appears to be two closely spaced pits is actually one spanned by a natural bridge. It formed when a resistant or stronger portion of the roof remained when both sides caved in. The enlargement (right) shows light that passed under the bridge shining on the pit floor to the left of the bridge.Image ID: M113168034R
