1958 Map of Grand Portal Point

About this map

Grand Portal Point and the towering formations of Pictured Rocks dominate this coastal survey along the southern shore of Lake Superior. The interior landscape within the Hiawatha National Forest is defined by a dense network of glacial lakes and dramatic water features, including Spray Falls, Mosquito Falls, and Chapel Falls. This 1950s data, updated for a 1970s publication, reveals a wilderness largely shaped by its hydrology, where names like Beaver Lake, Trappers Lake, and Sevenmile Lake suggest a history of early woodsmen and seasonal activity. A Lookout Tower near Buck Lake serves as a primary man-made landmark in this wooded expanse, which straddles the border between Alger County and Schoolcraft County. The map provides specific detail for hikers and historians tracing the original forest trails and drainage patterns of the Mosquito River and Spray Creek.
