GRAND MARAIS, MI (AP)-- A portion of Upper Michigan's Grand Sable Dunes has been closed due to erosion.
Park officials announced Tuesday that the northeast section of the dunes was closed by the National Park Service. They said it is rapidly eroding into Sable Creek and Lake Superior.
The park superintendent said the 14-acre eroded area poses a threat to the safety of visitors. He said the park is continuing to evaluate the extent of the erosion.
Park staff said the trail to Sable Falls is still open.
The Grand Sable Dunes are located at Pictured Rocks National Lakeshore in Grand Marais.
