This is the Moon of our dreams. Craters overlap, butt against each other, and extend to the horizon. Here that isn't very difficult because 114 km wide Moretus (foreground) is already at 70°N. Moretus, named for a man from Belgium (like Leo but 400 years earlier), is a larger version of Tycho, but a little less deep (4.5 km vs 4.9 km) perhaps because it is older. The greater age is evidenced by its lack of rays, and the absence of evidence of the impact melt that must have once veneered its floor. Perhaps one day the slope along its southern wall will provide easy wheeled access to its floor - but I am not sure why anyone would want to go there except perhaps to see the " rel="nofollow rille along the eastern edge of its floor. Nearly touching Moretus to the south is Short and poleward is the step-down triplet of Newton, with smooth floors visible. Beyond is the tall mountain that seems to be near the rim of Cabeus. This is, I think, the M1 of Whitaker's classic 1954 map. The other peak on the horizon may be M3, but to confirm requires Jim Mosher's LTVT to carefullly plot it. Its time for someone to accurately identify all the classic (Schröter and Whitaker) south polar peaks on the LRO polar mosaic.
