Hand-colored map of Grand Portage Reservation and Pigeon Point showing Indian allotments, tribal land, non-Indian owners, existing main roads, proposed main roads, and contemplated extension (northwest corner) of reservation boundary line as agreed with U.S. Forest Service.
Map clearly drawn to study the routes of proposed roadways. Large scale map from township 62 north on the west, Range 5 East and 6 East on the north and Lake Superior on the east. Shows Canada, the Pigeon River, reservation boundary, Mineral Center, roads and rivers. Hand-inked topographical details. Customs houses were noted where Highway 61 crossed the border (at the Pigeon River). Shows Swamp Lake and the Reservation River. Pencil notes were likely Ernest Oberholtzer's later marking route approved by U.S. Bureau of Roads.
