Ron Carswell recently sent in an email with a article about Forsyth County Corundum. From his email:
Thought I would share a little information about local Forsyth County geology that I have been investigating for many years as an archaeology enthusiast. Many prehistoric rock quarries existed in the now Forsyth County and Yadkin County areas that I have studied. The quarry efforts by early Prehistoric people impacted these geological environments extensively but clues have been left that identify the geological events that supplied rock materials used for stone tools and components. Hope you can identify this as a positive scientific effort in a geo archaeological nature. I have max amounts of data and artifacts on this subject.
