Providence College American Studies Department Chair Keith Morton led a group of eight people on a walk to Margaret’s Cave, the place where Roger Williams was sheltered during the winter of 1636 before going on to Omega Pond. The group included Lende McMullen and Elissa Tardiff of the Carpenter Museum in Rehoboth and Steve Greenleaf of the East Providence Historical Commission. Keith lives between the Chace Farm and the D’Allesandro Farm near King’s Rock. He gave a history of the area including Massasoit Ousamequin’s Pokanoket Tribe who nursed Williams back to health at that location.
