Introduction 
Observations and studies of others. The area comprised in the 
Bellevue quadrangle includes portions of Sandusky, Erie, and 
Huron Counties. N. H. Winchell, in his Report on the Geology 
of Sandusky County merely refers to ^Hhe Lacustrine sand,’’ 
which caps the limestone ridges, as ^Hhe only observable changes 
of level.” In the Report on the Geology of Erie County and the 
Islands, J. S. Newberry only mentions ^Hhe lake ridges which 
traverse the county from east to west” as among ^Hhe most 
interesting features in the surface geology of Erie County.”^ 
Report on the Geology of Huron County, by M. C. Read,^ contains 
several interesting allusions to the work done by the ice-front 
lakes. He noted ^Hhe old water plains, diversified by sand dunes 
and remains of old lake beaches;” he noted that the sand hills 
and associated ridges have the same elevation above lake level; 
that ^Hhe irregular, winding outline” of the ridges and the bor- 
dering dunes resemble the results being produced today by waves ;
