We've had a pretty good run of cool clear nights as the moon is approaching 1st quarter. It was a perfect time to capture some close-ups of the incredibly varied Moonscapes. A close inspection of the shadows cast into the crater bottoms shows just how jagged the peaks can be rimming the craters. The largest, very round and flat-bottomed crater in the bottom picture is the best example. This crater, named after Archimedes, is about 50 miles in diameter and 1.3 miles deep. For reference, the Grand Canyon is about 1 mile deep, on average.
