Isle Royale–Keweenaw Course —
John & Ann Mahan, Instructors
Beginning in 2002, John and Ann have been instructors for lifelong learning courses at Isle Royale and Michigan’s Keweenaw Peninsula. In these week-long courses, the groups experience the world's largest freshwater sea and its island wilderness national park, along with the Keweenaw Peninsula (Isle Royale’s geological mirror-image sibling).
Isle Royale National Park encompasses an archipelago of approximately 400 islands, 99 per cent of which is legally designated wilderness. It is the site of the world's longest running predator/prey study (wolves and moose), and many other scientific inquiries into how the natural world works.
Upcoming Course: A new Rock Harbor Lodge policy allows only one course per organization.
Our 2025 course will be June 15-21, 2025.

Isle Royale–Keweenaw Course — begins on Sunday with an orientation session, and a multi-media program about Isle Royale. The next day includes morning lectures followed by a field trip on Michigan's rugged Keweenaw Peninsula, taking in scenic vistas of rock-bound coastlines, sand dunes, waterfalls, a historic fort, and lighthouses — all while learning about the area’s human and natural history.
On Tuesday, we experience Lake Superior's open horizons as we journey to its largest island. On Isle Royale, lodging is at Rock Harbor Lodge, with rooms overlooking Lake Superior.
In the following 4 nights and 3 days, boat trips and guided hikes take participants to Rock Harbor Lighthouse, a historic fishery, the wolf-moose research station, offshore islands, a bog (with carnivorous plants), and coastal hikes. Some participants canoe in peaceful Tobin Harbor.

The Mahans give presentations and talks on geology, island biogeography, flowers and other plants, and human connections with the lake. Other experts also give talks, including researchers from the Isle Royale wolf-moose study.
On Saturday, another Lake Superior open water crossing returns us to the mainland and the closing of the course.
These are always groups of congenial and adventurous people, and we all have a great time together. We celebrate our shared adventures with images from past courses.
