Isle Royale, off the North Shore of Lake Superior, was designated as a National Park in the early 1940's.  At that time, there was a vibrant community of commercial fishing families on the island.  One of those families was the Sivertsons.  In this edition of WTIP's ongoing series, Moments in Time, Stuart Sivertson of Duluth remembers his boyhood summers on the island and recalls his family's long connection to the place.
