Cool stuff. Some of the gray stuff around these parts is a Moline chert. Sparkly ones are sometimes Hixton chert from WI sandstone. A lot of stuff we've stumbled across is the good local material know as starved rock chert (aka oneota). My 7 yr old made an arrowhead pinewood derby car a few weeks ago.
