The Line 3 route traverses land that Native American pipeline opponents say is protected by US treaties with Ojibwe nations
There are numerous sites in Minnesota, along the new Line 3 route, where water protectors have set up camp. Much of the route goes through tribal lands, as well as Minnesota’s iron range and areas popular for recreation, including hunting, fishing and people enjoying the outdoors.
It is a lush, wooded part of the state, thick with birch and pine trees, pristine lakes, rolling creeks and lakes filled with wild rice, an agricultural product that is historically significant to the Ojibwe.
