Parallel- flaking, some points with similar flaking were found at the base of a big bluff in Nebraska. That bluff was named after an early fur trader named Hiram Scott. He worked for the Rocky Mountain Fur Company. He died there next to his bluff in 1828. His cause of death was not recorded in the company journals; his name was simply struck from the company's payroll. I like to think he died with a Southern Cheyenne arrow in his heart rather than dyin' of fever or some such.
