Have you did any research or thinking about the Bluestone River. Swift I believe mentioned it a couple of times. Then on the Guest and Jefferson Map there is a "Remarkable Rock" shown. I believe this to be Pinnacle Rock near Bluewell, WVa. Daniel Boone lived not too far down this road near Pounding Mill and I believe he followed the Swift Party around trying to find the location of the Silver Mines. There is also a vein of silver in the Tazewell, Va. area as a man named Lefew counterfeited silver dollars in the area. That silver vein runs under the Blue Ridge Parkway just West of Lover's Leap on Rt. 58 and then runs through Ingles' Ferry where George Clark owned the lead and silver mines for a while and then on into eastern Kentucky. I am sure this is the vein that runs through the corners of Virginia, West Virginia and Kentucky. You asked others to share so there you go. Also Swift did own the land from Williamson West Virginia to the Levisa River including Pikeville, Ky. at the centered on 100000 acres or about 12 miles lone and 10 miles wide.
