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.
This is a state of Minnesota map prepared by Stafford King, State Auditor, St. Paul, Minnesota. The map shows state parks (22) and Monuments (8) as well as state forests. We assume that Oberholtzer has hand-colored the Superior National Forest with green crayon including a portion south to nearly Beaver Bay and portions near Vermillion Lake and including State Forests and Burntside Forests. A hand-drawn orange boundary line is undefined. On the reverse side of the map we find MN town and city population figures from 1930 census reports. Minneapolis = 464,356 and Rochester, MN = 20,621.
