Veteran naturalists Kate Crowley and Mike Link know the shores of Lake Superior in a way few others do—in 2010, they hiked the full circumference of the lake, gaining a whole new perspective on the greatest of the Great Lakes. In three days of hikes along the Minnesota shoreline, they’ll share their extensive knowledge of the natural and cultural history of the area, and help you identify and catalog your own observations. Join them for a weekend of challenging but rewarding exploration. Unable to participate in the full experience? Options for one-day ($95) or two-day ($170) enrollments are possible (call for information). Materials fee covers daily lunch and transportation.
