I wonder if iridium traces could be found beneath.

I think this calls for a field trip to obtain core samples!

Dismal Swamp is an odd place, geologically.

It is higher in elevation than surrounding land.
Several streams flow down and out of it. It is like a sponge, with vegetation building up the level each year. Probably due to the pan structure below.
