Just a guess but...
Twin impact, a meteorite that broke in two parts during impact or short
ahead.
Maybe it was two loosely attached bodies that fell or a broken body.
Anyhow, they should have been really close in mass to create such a perfect
twin crater and the two plumes of ejecta.
The nice rim in the middle and the plumes could only be formed if the two
craters were formed at the same time.
If this could form, then there should be a whole range of twin craters
with different size craters and the ejecta plumes in different angles.

Hello List,
Any ideas as to what went on here? Check #60 - one of the MOST unusual
crater formations I have ever seen.
All the best,
Greg
