USGS Topo · Published 2011About this map
Grand Portal Point and the towering formations of Pictured Rocks define this northern stretch of Michigan where the land meets Lake Superior. This survey documents a wilderness landscape shaped by water and stone, featuring distinctive landmarks such as Sail Rock and Chapel Rock. The hydrology of the area is characterized by short, steep drainages that create dramatic drops before reaching the lake, including Chapel Falls, Mosquito Falls, and the lakeside Spray Falls.
