The distinctive triangular shape of the ejecta indicates that the impacting body probably hit obliquely, traveling from southwest to northeast.

The very dark area on the northeast side of the crater is probably covered by smooth material such as fine-grained sediment.

The dark halo may have been caused by an atmospheric shock or pressure wave produced by the incoming body.

These flow-like features may have formed by fine-grained ejecta transported by a hot, turbulent flow created by the arrival of the impacting object.
