cptpies,

Yes indeed the crater is Post Tertiary. By the way have you managed to review the area with Terrain Layer "on" on GE? Definitely you would notice the eroded ridges on western side as well. The only reason for soft erosion pattern on western side is due to relatively soft formation (shales and claystone beds).

I am unable to find any regional fold on eastern side to confirm the "fold theory" rather I do notice a slight depression of brown beds (with its curvature slightly dipping into the crater) with the radius going WSW - almost in the center of the crater.

The bending of hard beds (of east) on the edges near streams are usually due to erosion of softer material beneath the hard rocks.

Further please observe the radial drainage pattern by just ignoring the main regional drainage system for time being. To me the drainage pattern should be corresponding with features on which they are been generated .

The case seems to be of heavy erosion of the crater due to regional uplift as indicated by the deep incision caused by the drainage (it can be confirmed from the drainage feature on the regional level).

To me if lets suppose the age of the crater is 10 Ma there is still pretty much chance for most of its feature to be eroded away due to heavy erosion.

To me this topic is still debatable
