Now that basin is fascinating, not just for the radial valleys, but for the darker mare-like features on its floor. Someone needs to do some crater counting there when the resolution gets good enough!
Also, whats with that lobate feature to the right of the basin which terminates near those fossae? Almost looks like the basin has overflowed (cryo?)mare materials in the past. Does anyone else see that? P |

Does anyone else see that? Of course we do see it. That part immediately caught my eye also on the image composite that eliBonora provided. It seem that the crater walls might be slowly filling slowly, if that turn out to be correct they truly would be doing so at a glacial pace. I cant stop wondering if those larger chunks might be ice or aggregations of the darker surface material that stick together. In addition there appear to be terrace all round the southern half of the crater that make it seem that the southern region got a higher elevation. |
