2-shay! As proven by the mashed cracks in the tracks, and the remnants of some surface polygons in the lateral ridges, the rocks obviously moved across a dried and fractured surface. NOT a slimy wet one.
Unless one posits a very light precipitation event to dampen and slick-up the surface, but not penetrate to any significant depth.
Lack of a "terminal moraine" is also odd, but completely disproves any theory which posits that the rocks moved over a muddy surface. As any kid will tell you: you can't push anything through mud without it piling up (very quickly) in front.
