Notes -
The following is the beginning of USGS Fact Sheet 020-98.
In February 1995, a 1,600-foot stretch of popular beach at Sleeping Bear
Dunes National Lakeshore suddenly slid into the waters of northeastern Lake
Michigan. The National Park Service (NPS) immediately requested the
assistance of the U.S. Geological Survey (USGS) in evaluating the hazard at
the lakeshore. To protect the public, USGS and NPS scientists are
conducting studies that will help predict when the landslide-prone area
will move again.
