I came across this old file cleaning up and saw that Flint Ridge Flint
hadn't been entered yet. It is such a unique and famous rock.
Because of it's association as a main stone tool and projectile point making material to the Native Americans,
the many different colored patterns, and just all the variety,
it has always been a favorite of mine. I would like to get up to east-central Ohio sometime and view the lay of the land.
That being said,
Flint Ridge Flint is a perfect example of a stone being called something it isn't.
Not in the furthest stretch of geological formation could FRF be flint. It is a chert.
The use of the word flint comes strictly with it's connection and use by Native Americans.
(And I've always thought it makes for a pretty classic jasper.
)
I found a very good report on Flint Ridge Flint here;

I'm sure you all would enjoy the read and pictures.
Here are a few pics.
The first is of the milky white "bull" rock of the chert layer.
It is very good knapping material and "can" turn all sorts of colors when heated. Pic 2.
