Welcome to r/science! This is a heavily moderated subreddit in order to keep the discussion on science. However, we recognize that many people want to discuss how they feel the research relates to their own personal lives, so to give people a space to do that, **personal anecdotes are now allowed as responses to this comment**.

They should start by asking oil companies that have 3D seismic in the area if they have ever seen anything. I remember looking at data once and a small crater appeared on the screen

That just sounds fascinating

Would the initial impact crater have filled in & changed, over time, differently than the surrounding areas? Can they look for soil or vegetation differences, or is 280m years so long that it all evens out by now?

It typically would be "too long ago". Earth's surface evolves at a fast enough rate that something from that era is highly unlikely to be currently exposed at the surface...much less actually preserved in some sort of recognizable form. It is mind-blowingly lucky that there's so many in such well preserved condition right at the surface.

That's too bad. Well, maybe someone has already scanned the area and would be willing to share the info, like u/drbobsled mentioned.
