Call the crew! You need to assemble your best geocaching team to capture the daunting terrain 5 cache at ‘Treasure Island.’ In the middle of the meandering Potomac River between Sharpsburg, Maryland, and Shepherdstown, West Virginia, sits three weathered stone pillars of what appears to be remnants of an old bridge. Life has found its way on top of the eroding pillars. Tree roots grapple the sides, clenching onto its weathered base, and provide holds to stabilize those who climb to the cache.
