i’m not that close to seymor or columbus. i am sort of between bloomington and french lick.
Sure, it was more active a hundred million years ago, but think about how close you are to that big crack in the Earth called the Wabash, and how close the Carmel Fault is to that part of the country.
Last little quake on that fault (about 5 years back) knocked cracks into stone structures throughout Monroe county.
When the mantle oozes and cracks form, a certain type of volcano can work its way to the top through old vents ~ really ancient vents too!
There's a volcano East of the Hills of Brown County and West of the HIlls of Brown County. They're old but they are still chugging!
