740 GLACIAL FORMATIONS OF ERIE AND OHIO BASINS. 



the northwest, while outside the Defiance moraine much of the shore fronts 

 the northeast. An examination of the beaches has shown that portions 

 which front the northwest are uniformly stronger, other conditions being 

 equal, than those fronting the northeast. This is true not only of the 

 Maumee beaches but of the Belmore beach, the beaches of Lake Warren, 

 and the beach on the present shore of Lake Erie. This seems to indicate 

 that heavy waves were chiefly raised then, as now, by the winds from the 

 west. In addition to this advantage of frontage toward heavy seas, the 

 portion inside the Defiance moraine had on the whole deeper water near 

 the shore than that outside, so that large waves were less liable to have 

 been broken at some distance from the shore than in the district outside 

 the moraine. 



CAUSE FOR TWO BEACHES. 



The cause for the occurrence of two beaches in connection with Lake 

 Maumee, as already suggested, is apparently found in the opening of the 

 Imlay outlet, which increased the capacity for discharge and produced a 

 lower level than that which prevailed while only the Fort Wayne outlet 

 was in operation.
