Angular craters

If you look for long enough you'll find square, octagonal, hexagonal, pentagonal craters on Moon and Mars. Sometimes you can see reasons why they are preferentially that shape (e.g. edges following regional fracture sets, or deformed by cross-slope soil creep, or interactions between different craters). Sometimes you can't.

Even Barringer crater on Earth is very square when seen from overhead.

No reason to get excited, IMHO.
