Geomorphology . Dunes and Pleistocene 

 lake sands characterize the beach. 

 Shoreline orientation is N.24''W. 

 Location is just south of a paved 

 highway between Lake Michigan and 

 Duck Lake. Recent erosion has 

 endangered the highway and large 

 concrete slabs have been dumped along 

 the beach where the highway is close 

 to the lake. Net littoral drift is 

 to the south so that the site is in 

 the lee of the protected beach and 

 is deprived of sediment transported 

 downdrift .
