Garden find, not sure if any are artifacts. Help please!

Digging in my backyard in El Reno, Oklahoma and found a bunch of rocks, some look like they have knapping marks but I'm not sure whats what. They sound kinda like glass clinking together.

It looks like debitage(flakes) and pieces of chippable stone of 3or4 different types. Your backyard is part of a camp or something unless previous owners were rockhounds. Big yellow flake looks like a scraper.

The yellow piece looks like a utilized flake to me (too), other pieces are debitage as welsbury stated.

I agree, the yellow one was the only thing I was sure was a tool. Thanks for weighing in on the matter! I planted the garden so anymore digging will have to wait a bit!
