Geomorphology . Beach at Big Sable 

 Point has a shoreline orientation of 

 N.7°E. This part of the eastern 

 Lake Michigan coast is one of the 

 most extensive dune areas. Dunes 

 extend several miles in either 

 direction from Big Sable Point and 

 a few miles inland at the point. 

 Dunes are covered with grass and 

 small bushes. Virtually no gravel 

 was found, reflecting the proximity 

 to dunes.
