Dead Trees, Grand Sable Dunes, Michigan, 1991

Photograph by Phil Schermeister

Long-deceased trees cling stubbornly to the steep flanks of Grand Sable Dunes in Michigan's Pictured Rocks National Lakeshore. The precipitous dunes, left behind by ancient glaciers, rise some 300 feet (90 meters) above Lake Superior and spread over 5 square miles (13 square kilometers).
