Ah, the Death Valley Racetrack! I knew about the ice sheets doing the deed. Since these guys were out there watching, they should have brought back pictures!
Interesting that they didn't even see the rocks moving even though after the fact they realized it had occurred. This would be a great application for a time lapse video.
Looks like a project
