I've walked creeks where Hornstone is naturally found, nodules, tabular flint, raw chunks--I've seen hornstone from other areas of Kentucky, Tennessee, several varieties of Cobden (Illinois Hornstone) in their natrural areas--nothing like this flint with mica(?) giving the flint a definite sparkle as light hits it. There is some trace of iron in the flint, see the red stem color. I know from some pieces marked (in the collection) that the hunter was very familiar with the Wabash River, Illinois and Indiana. My working assumption is that the piece, being in the Dixon and/ or Gary point type was an Illinois find. You can still see some soil in deep crevices of the flint, so it wasn't over cleaned: 2&5/16" by 1&1/2", moderately thin at 5/16" max. The stem isn't noticeably more ground than the wear on the blade edges, so if the Woodland maker dulled the stem it wasn't by much. How much longer the blade started is hard to say, but tip-to-barb I expect was twice the present length--nice pressure chipping, the blade edges are well formed. Lifetime guaranteed authentic, period. Shipping is $6.00, check or M.O>s are welcomed. Sorry, I do not use paypal--Roy A.
