Lunar Anomalies #11

Not really an 'anomaly', but an interesting hexagonal crater.  I've seen these before so it's no surprise, but I wonder if any human eyes have ever seen this particular one?  Regardless, it's pretty cool and very enigmatic.  Even the inside of the crater is strange looking.  This popped up as my #1 anomaly for this particular image section.  This is LRO dataset M1502014536LC.
