The document discusses the lost silver mine of John Swift, an 18th century frontiersman, and the ongoing mystery around its location. It provides background on Swift's life, summaries various theories about the mine's existence and location, and highlights evidence found in historical records and landmarks that provide clues pointing to areas in Eastern Kentucky and Southwest Virginia along Pine Mountain and the Pound Gap as the potential locations of Swift's mine and caches of silver. The author believes Swift discovered an ancient storehouse of silver left by Native Americans rather than an actual mine.
