How is this supposed to work with the sedimentation? The glass spherules under the lake are maxxing out 5-6 meters below the surface. Where does the material on top of that come from, and why didn't it fill in the lake, but leave it intact & with ridges?
Second, if you think of an impact at an angle, the crater and its ridges form an ellipse. If its coming very flat, the structures might look rather parabolic, but still bent inwards. In the article, the north ridge is bent outwards. How? Questions over questions.
