SANDUSKY BAY AND CEDAR POINT 1838 
The effect of some of these same storms in producing lasting 
changes on Cedar Point and elsewhere about the bay will be 
mentioned in subsequent chapters. Storms of much less vio- 
lence than these seem awful to those who are on the lake at the 
time. On May 3lst, 1903, the water striking the Ohlemacher 
dock on Marblehead was dashed so high that people at a distance 
could see it over the tops of the limekilns and on another occasion 
Alex R. Clemons estimates that the spray went more than fifty 
feet above the top of this high dock. In front of the large stone 
house which stands near the lake in Marblehead village a piece 
of limestone estimated to weigh two and one-half tons was 
broken loose from the bed rock and moved along shore twenty- 
seven feet by a single storm. Looking from this place Mr. 
Clemons has counted as many as seven wrecks, all in sight at one 
time. 
EFFECT OF TILTING OF THE LAND. 
LAKE BEACHES. 
When the glacier had retreated beyond the northern 
boundary of Ohio a lake extended along the southern border of 
the ice. The south shore of this lake was at first about twenty 
miles south of where Sandusky now is. Its western extremity 
was at Fort Wayne, Indiana, whence the water flowed to Hunt- 
ington and via the Wabash and Mississippi to the gulf. As the 
ice melted from the southern part of Michigan, outlets were 
formed into the Grand River valley through which the water 
flowed to another glacial lake occupying the southern part of the 
basin of Lake Michigan and thence toward the Mississippi through 
the depression now utilized for the Chicago drainage canal. The 
later outlets were lower than the earlier ones and consequently 
the lake level fell and each time it fell its southern shore came 
nearer Sandusky. Each position of the shore is marked by a 
beach. - The highest beach extends from Fort Wayne through 
Van Wert, Tiffin, Pontiac, the southern part of Norwalk and 
Berlin Heights, from there on east continuing only a few miles 
from Lake Erie. The middle beach extends through Bellevue, 
Monroeville, the main street of Norwalk, Berlin Heights and 
Elyria. The lowest beach passes through Clyde, south of Milan 
through Berlin Heights and along Euclid Avenue, Cleveland, 
through northwestern Pennsylvania and western New York. 
Each beach, when formed, must have been approximately 
level as it followed the shore of a lake. But they are no longer 
level. Leverett has found that the lowest one is 168 feet higher 
at Crittenden, N. Y., than at Cleveland, showing that the land 
between these places has been tilted to that extent. Old beaches
