I saw some pictures of the blue chert someone sent to be that was found in Lumber City. They were in the river at low water on the highway from Hazlehurst, on the side where the Telfair Forest Products is. I do see a boat ramp down their between the highway and the railroad trestle. It was some pretty good size pieces too.
I don't have a picture of the bluer chert but here is one they showed me.
That`s not blue ice. That looks more like an agate.
