I found all of these stone tools in the lake bed of Lake Jordan. It is an impoundment lake in central North Carolina. When it was filled after the dam was complete it flooded farmland and land inhabited by the Native Americans long before Europeans and Africans came to the area. If you walk the lake shore when the water is low due to drought, it is possible to find stone tools and points in the mud. I keep them in a Super-8 film can, just to add to technological irony. Taking them out and holding them gives me a sense of connection to the makers of these tools.
Strobist info: Speedlite 430EX II with plastic diffuser mounted just above level with the tools on a light stand. The camera is mounted vertically above the tools on a tripod. Yognou YN-622-C ran triggers.
