A floor fracture and central peak structure on the floor of the Moon's Humboldt Crater--128 miles (207 kilometers) in diameter-- that formed directly after impact. Intrusive volcanic activity likely caused the floor of the crater to lift up and then fracture. This image is viewable in 3D using red-blue glasses. It was taken by NASA's Lunar Reconnaissance Orbiter.
