drumlins north and northwest of Richfield Springs. This westward flow of 

 the Hudson-Mohawk ice was opposed by an eastward flow of the ice in the 

 Ontario basin. At a later stage an ice-free space was left between the two 

 opposing lobes, and the glacial waters then held in the Mohawk Valley I have 

 called the Herkimer Lake, which had its first outlet at Summit Lake, and 

 later at Cedarvale, to the Susquehanna. As the depth of ice lessened in the 

 Champlain-Hudson Valley, the Mohawk lobation shortened and the Mohawk 

 glacial waters spread eastward and found escape along the face of the Hel- 

 derberg scarp, and at a lower stage through the pass at lielanson. These 

 eastward-escaping waters are named the Schoharie Lake. 



LAKE MAUMEE, IN OHIO 

 BY FRANK CARNEY 



iA1)stract) 



A detailed study, during the past summer, of the Mentor, Chardon, Perry, 

 Ashtabula, and Conneaut quadrangles raises a question as to this glacial lake 

 extending east of the Euclid topographic sheet. The widely disconnected 

 gravel and sand areas and weak terraces appear to be the work of local ice- 

 front bodies of water and of ice-front streams, instead of an eastern extension 

 of Lake Maumee, as heretofore suggested. 



Discussion 



Mr. F. B. Taylor: I accompanied Mr. Leverett, in 1899, in an effort to 

 trace the Maumee beaches to an end eastward from Cleveland. The results 

 are published in Monograph XLI, United States Geological Survey, and I am 

 sure that a careful reading of his description will show that he discriminated 

 closely between river-made features of ice-border drainage and wave-made 

 features of the old lake shores. The terrace at the Garfield monument ap- 

 pears to be the delta deposit of a river coming from the northeast along the 

 front of the ice, and the scoured bed of this river was observed farther 

 toward the northeast. The bed of the river descends slightly toward the 

 southwest, and the terrace is above the level of the Maumee beaches. Beach 

 fragments corresponding to the second Maumee beach wei-e found at frequent 

 intervals as far as Girard, Pennsylvania, and their height above the Belmore 

 or Whittlesey beach, next below, was carefully noted and found to be uni- 

 form, showing no appreciable rise as far as Girard. Most of the beach frag- 

 ments were rather faint, but often quite distinct, as I remember them. Our 

 interpretation of these fragments as representing the second Maumee beach 

 seemed to be strongly confirmed by their horizontality when compared with 

 the much stronger Belmore beach below. As I recall Mr. Leverett's state- 

 ment, he found no certain evidence of the upper Maumee beach east of Euclid, 

 all the distinct shore features above the Belmore and east of Euclid belong- 

 ing apparently to the second beach of Lake Maumee. I am inclined, there- 

 fore, to believe that Professor Carney has missed the faint forms of this beach 

 east of Euclid.
