sonora flint

[trent colvin]

thanks for the info... I can't use any rock from a creek or river unless it is covered by water all year. I am looking for field rock... any help?

I would start with the Kentucky Geological Survey: http://www.uky.edu/KGS/
If you can't find the info you're looking for at the site, click on the "Contact KGS" link and send them an email. I bet they'll be happy to help.

Hope this helps

In most state and federal parks it is illegal to remove anything, including rock. If you are around a lake that has outcrops, you can probably collect the rock that has not been worked. Artifacts, whether underwater all year or not are protected. Some of the best places I've found is by looking at Geological Quadrangle maps and finding areas where streams cut through formations that have chert in them (the maps have a description of each formation and will list chert if present). Easy access can be found where bridges cross the stream. Check for gravel bars. You'll find a lot of chert in those. Formations in your area that have chert: Ste Genevieve (your Sonora chert is in that formation), St. Louis, and Fort Payne. All Mississippian aged formations.

What is knapping? I honestly haven't heard of this before.

Flintknapping is how stone tools (Indian arrowheads, for example) are made. Various stones and antler are used to shape the flint or chert into the desired shape.

Knapping Flint Is The Process Of Taking A Large Rock And Striking It So It Will Produce Flakes. With Proper Technique, The Rock Will Become Thin Enough To Make Projectile Points And Knife Blades
