Triesnecker is a 26 km wide complex crater whose ejecta is draped over the adjacent smooth terrain, but the feature of interest is a labyrinth of narrow linear rilles to the east. I don’t know why the rilles are here. Some rilles in other parts of the Moon are surface expressions of volcanic dikes (or dykes as spelled in UK); if these are also, the question is why was there such a concentration of dikes in this region? The low lighting and high resolution of Stefan’s shot emphasizes the undulating ground that the rilles cut.
