2. Tectonics Related to Cretaceous - Tertiary Impact
This is **not** an impact crater / structure, but still
it represents the physical consequences of the Chicxulub
impact. At Moscow Landing there is substantial evidence
of earthquakes and faulting associated with this impact.

Kilmichael Structure, Mississippi - (probable impact
structure, but still looking for either shocked quartz
or evidence of impact metamorphism. Some people suggest
that it is indeed tectonic in origin.)
