Good bit of work there
Actually, you've missed some of the ejecta blanket off to the SW...there's more there. There's also some more to the NW but it's been heavily eroded.
My only concern about it having come in from the SW is that if it had come in at a relatively shallow angle, you would have a more elongated crater off to the NE and the majority of the ejecta blanket would show a similar pattern. It still may have come in from that direction but probably at a relatively high angle of descent...above 60 degrees at least, to produce such a round crater. Those really dark spots, I'd like to get a look at those. I wouldn't mind betting some are craterlets from either rock thrown out of the impact site or bits that may have come down with the main bolide....if it's not just ejecta.
Any more craters??
