1983 Map of Grand Portal Point

USGS Topo · Published 1984

About this map

Pictured Rocks National Lakeshore dominates the shoreline of Lake Superior on this Michigan Upper Peninsula survey. The map records the intricate network of inland water and coastal landmarks within Munising, including the prominent Grand Portal Point and Chapel Rock. This late-twentieth-century study shows a landscape deeply defined by recreational and conservation management, emphasizing the Lakeshore Trail as it winds past the Chapel Beach Campground and Mosquito Beach Campground. Inland, the drainage of the Mosquito River and Spray Creek feeds a series of cataracts including Chapel Falls and Mosquito Falls, while the southern reaches of the quadrangle transition into the Hiawatha National Forest. Researchers can trace the hydrological connection between Chapel Lake and its smaller neighbor, Little Chapel Lake, providing a detailed look at the backcountry before modern digital mapping.
