Astronomy Adventure – Valleys Of The Moon

This is the very southern region of the Mare Fecunditatis and the mountainous and cratered region that separates it from Mare Nectaris. The fully lit crater with the central peak on the right is Petavius and below it with the single visible crater on its interior floor is Fernurius. The smaller crater to its left with a central peak is Stevinus, with Snellius just above that. The Vallis Snellius is clearly visible dissecting the two, cutting across the southern edge of Snellius. The darkened crater with the just barely visible central peak to its left is Reichenbach, with Rheita E the elongated gash to its right and Rheita to its south. Below that is the deeper Vallis Rheita.
