726 GLACIAL FOEMATIONS OF ERIE AND OHIO BASINS. 



in the vicinity of Waiiseon and Pettisville, where it crosses the Defiance 

 moraine; but ait Fairfield, Mich., it stands onlj^ 20 to 25 feet lower than the 

 upper beach, or about 775 feet above tide. Near Ridgewa}^ it seems to be 

 about 775 feet, being only 15 feet below the upper beach. At Birmingham, 

 as already noted, it is 780 feet, or 29 feet lower than the neighboring part 

 of the upper beach, while at Imlay it is 849 feet. 



THE SOUTH SHORE OF LAKE MAUMEE. 



In the examination of this shore attention was given principally to the 

 extent and character of the upper beach. The second beach seems, however, 

 to be developed along much of the shore. From near Cleveland eastward 

 into Pennsylvania, as indicated . below, it appears to be the only beach of 

 Lake Maumee, that part of the lake basin having been occupied by the ice 

 sheet at the time the upper beach was forming. 



DETAILED DESCRIPTION. 



Along the south border of the Fort Wayne outlet east from Fort Wayne 

 there are two ridges of sand difPering a few feet in level. The lower and 

 more fragmentary one is utilized by the Fort Wayne and Van Wert road 

 for a part of the way between Fort Wayne and New Haven. The higher 

 one lies a short distance south, along the base of the blufi" of the outlet. The 

 loAver ridge is only 3 to 5 feet in height, but the higher one is generally 6 

 to 8 feet. The lower ridge appears to be low enough to connect with the 

 second beach, but the higher one seems to be above the level of that beach. 



On the east side of the Sixmile channel there is a very prominent hook 

 where the beach turns into the channel. A gravel pit exposes its structure 

 to a depth of 17 feet. The upper 5 feet is quite sandy, but below this 

 depth there is gravel which shows cross bedding with southward dip. The 

 beds also dip toward each side of the ridge in anticlinal fashion. The crest 

 of this recurved ridge stands about 25 feet above' the Nickel Plate Railway 

 station at New Haven, or 786 feet above tide. It rises a few feet above the 

 usual altitude of the upper beach and probably stands at least 5 feet above 

 the highest lake level. 



From this hook eastward the upper beach is very sandy and in places 

 low dunes appear. Wells show the sand to have a depth of 9 to 18 feet. 

 The ridge rises abruptly about 15 feet above the lake plain on the north, 

 and 6 to 8 feet above a sag on the south. The sand ridge terminates neair
