I was looking at data in the SE USA with a photo overlay. To my surprise there was a striking circular feature. Eventually i realized it was the area of the Savannah River Project, one of three US bomb production sites.
In the late 1930’s a mostly rural site in Georgia was depopulated and fenced. All around the original site, the population grew.

I have a post scheduled for early June on magnetic data from the Savannah River Plant - not degraded! :)
No, what I originally saw as a possible astrobleme, is an artifact of a do not enter boundary.
Amazing!
