“spend an afternoon at the dunes!”
Grand Sable Dunes cover a 5-mile stretch along the southern shore of Lake Superior in the upper peninsula of Michigan in the eastern portion of the Pictured Rocks National Lakeshore. Glacial melt during the last major advance/retreat called the Marquette Readvance created the conditions for the formation of the Grand Sable Banks. Dominant northwesterly winds eventually caused blowing sand to become perched on the banks. Today, the Grand Sable Banks rise to heights of up to 300 ft. at a 35 degree angle from the shore of Lake Superior. The Grand Sable Dunes perched on top of these banks offers a desolate sandscape with jack pine forest near the edges.
