This beautiful lake lies on the international border between the United States and Canada, nestled within the Boundary Waters (BWCAW). The boundary line runs right down the center of the lake instead of following the land, resulting from a treaty establishing the border based on historical canoe routes used by voyageurs. The only access to the lake is by canoe through portages from Duncan Lake, or by hiking the Border Route Trail or Caribou Rock Trail. In many areas along the shoreline, cliffs rise 300 to 400 feet above the lake's surface, formed by hard slates that resist erosion, creating stunning natural scenic overlooks.
