Looks like some potential in that jasper. I cut my teeth on jasper cause that is a common material where I grew up just east of Yellowstone. Its like anything else, there are different qualities and sometimes a good sized piece that is not already fractured is hard to find. We had "Sheepeaters" in this country and they prefered agates and jaspers mainly because that was the local material and they were gem qauality knappers! Pokie
