Ernest Oberholtzer used this tourist information map for planning purposes, likely while serving in his role as head of the Quetico-Superior Council. He is educating about the impact of a proposed federal forest extension and noting sections necessary to be added to the national forest. Crayon-colored areas are shaded for designated forests: green = federal forest, blue = state forest, red = outline of proposed forest extension, and gray = necessary to be added to Superior National Forest under Quetico-Superior Council Program, now not included in federal proposal.
This is a map of the Boundary Waters region, and shows great detail on lake and river names. Area north of the international boundary is called "Hunter's Island." The roads and railroads are marked, as well as trails, ranger stations and telephone lines. Additions to the Superior National Forest Proclamation Boundary are shown using a reddish cross hatching.
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.
