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.[1] 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.[2]

In the late 19th century, loggers in the area built a wooden log slide from the top of the dunes at the Grand Sable Banks to Lake Superior below to facilitate the transportation of timber from the area.[3] The location is a popular spot to view the Grand Banks and climb on the dunes. Visitors may also take a trail from the Grand Sable Visitors Center near the eastern end of the dunes or stop along a section of the dunes that borders on Grand Sable Lake.
