Gmorn, All surface finds. I have only dug for a few times with not much luck. The 4 top pieces were all found when I was floating a water way, gravel bar finds. The clipped piece came from a wheat field.
Cool collection Fat. I need to get out looking again. When I flew over your area a week ago I was looking at all those sand blow outs below and thinking about all the artifacts that might be down there.
