letronne

118km Letronne Crater imaged from SLDEM dataset found at Map-A-Planet-2.  Snapshot in Meshlab of stl relief file, enhanced in Photoshop.  There are a few rilles in the foreground I haven’t seen mentioned elsewhere.  The advantage of a southern illumination.

They are not that easy to see even from orbit:  The WAC camera view
