From American Digger Magazine and the Relic Roundup internet radio show:
". . . relic hunter Robert Borhn will talk about one of the greatest moments in relic hunting and anthropology. After a bulldozer exposed human remains on Folly Island, SC, Robert notified the authorities. Determining that the remains were black Civil War soldiers from the 55th Mass, Robert spearhead work that resulted in not only a monument on the site, but reconstructed faces of two of these soldiers, and also reburial with full honors."
The dedication ceremony can be seen here:
You can listen to an interview about this here tonight at 9 PM EST on the Relic Roundup Show.
