Flint from the ridge is a highly prized by mineral collectors  who cut and  polish it into jewelry.
I got to visit and extract flint from the site many years ago as there are a couple of pay sites where you can dig for it .

Piece from my collection

Colors of red,blue,white and yellow can be found thru the flint which makes it very colorful and the interest in it as jewelry but Native Americans where more interested in it for its ability to hold a vary sharp edge essential for spear points when using a bow and arrow for taking game or killing a rival tribesman .
The flint from flint ridge is often found in excavations of native American camp sites here in Western Pa.
