The South Pole of the Moon is at 10 o’clock on the rim of Shackleton Crater. 20 meter data from a 1500 x 2100 original. 42 kilometers x 30 kilometers. It wouldn’t be a fair Marathon, though, the change in height here is 4.6 km. It’s a long way down, and the walls of the crater are quite smooth. This is corrected from an earlier image that was exaggerated in Z. This has the to scale proportions.
From overhead, gray tone shading by height. A correct representation.
The casting is 5″ x 7″ and a bit over an inch thick.
