An unfamiliar scene with elements of familiarity. Where on the Moon do we see a stripe of mare? And where does a range of mountains border a sliver of lava? Really only two places, inside the Cordillera rim and the Outer Rook rim of the symmetrical. Finally, at front left is a crater on the edge of a mountain. This does seem to be just a case of a chance impact near a pre-existing feature.
