My brother & I were out arrowhead hunting last sunday. We didn't find any artifacts worth mentioning, but we did find an ancient flint quarry. These nodules were picked up in 5 minutes. There are some that look to be 40± lbs just lying on the ground . More nodules than you can shake a spalling hammer at. This place has some of the largest nodules I have seen. They seam to be very good stone. Tower
