>>What can probably be agreed is that an impactor with an entry angle of 45* degrees could produce a round crater. Meaning of course that Meteor Crater, since it's not perfectly round as evidenced by the "bulges" in the NW and SE corners, must have been produced by an impactor with a trajectory much shallower than 45 degrees. Logically.<<
I don't know, but I wonder if the shape of the terrain upon impact(hills/gulleys etc) or perhaps a varied pattern of rock strength underground could have had some influence to the craters shape?
