What is wrong with Capella? Its next door neighbor Isidorus appears like an older version of Gutenberg G. Are these odd-interior craters associated with some property of the material they formed in or is it just a coincidence they are near each other? Capella has been overlain with a large secondary crater chain, radial to the Imbrium Basin, but it is not likely that the chain caused the crater's odd looks. So what did?
PS - Don't get excited by the pit in Capella's central peak - the LRO QuickMap gives no suggestion that it is volcanic.
