Anybody else see two fairly distinct, large impact craters on the lower edge of the photo? Looks like it to me. Formed those mountain ranges if so.
IMO the world-wrapping mountain/fault lines came about with lunar capture, but there was an impact about 2 million years ago, and there must have been other impacts before and since.
