Knife Lake, home to the Isle of Pines, is located in Lake County, Minnesota on the international border between Minnesota, U.S.A. and Ontario, Canada, with the Boundary Waters Canoe Area Wilderness (BWCAW) on the U.S. side and Quetico Provincial Park on the Canadian side. A U.S. Forest Service permit is required to travel to Knife Lake due to its location within the BWCAW and access is limited to canoe, snowshoe, ski or dogsled travel. The nearest road is 15 miles at the Moose Lake public access point and the closest town is Ely, Minnesota approximately 30 miles from Isle of Pines on Knife Lake.

During “soft” water season (ice break-up in late-spring to ice formation in early-fall), the most direct route to Knife Lake is via the Moose Chain to Birch Lake, through to Carp Lake, onto Melon then, Seed and finally, Knife. This is the route Dorothy often used with her aluminum canoe and motor. During the “hard” water season (passable ice on the lakes), Dorothy either used her snow machine or snowshoed to Moose Lake. During this time, there was also a winter route available that was slightly shorter.

The remaining signs of Dorothy’s presence on the islands include the Ribbon Rock (moved here by Dorothy’s nephews), a lilac bush near the summer tent area and Point Cabin, and an English rose bush near the summer tent area.

If you go to the Isle of Pines, you may notice open areas where buildings once existed as well as paths between those areas. Although no markers or signs are present, please note that no camping is allowed on the Isle of Pines.

The Dorothy Molter Museum has created custom maps and data sheets to help in trip planning for those interested in visiting the Isle of Pines from the Moose Lake landing (there are a variety of routes to access Knife Lake, this is only one). Data points include several of the building sites shown on the map.

Outfitters in the Ely Area abound and provide options for fully- and partially-guided trips, trip gear, meals and navigation. Additionally, there are several outfitters operating on Moose Lake that provide towboat services, reducing the travel time to Indian Portage connecting Sucker and Birch Lakes.

Friends of Dorothy Molter estimate that to visit her on her islands (Moose Lake to Knife Lake) it would take 4-4.5 hours to canoe (no motor), 7-10 hours to snowshoe and 45 minutes to snowmobile. No wonder so many people took their snow machine up to visit her in the winter!
