With all the recent emphasis on data from lunar orbiters it might seem that little interesting can be seen from Earth. But this excerpt from a large Hippalus Rilles mark where the edge of the crust bent and fractured. Why did this happen? Because the mass of the Humorum lavas to the left caused the center of the basin to sag, setting up strong bending stresses along the edges. The sinking also lowered the solidified lavas into a smaller volume, causing the mare materials to fracture and slide over previously adjacent parts, forming the wrinkle ridges. The near-terminator view shows a complexity to the ridges that can't be completely explained but does suggest how the ridges mark step-downs to the sunken center of the mare. None of this is new,, but it s beautifully shown.
