732 GLACIAL FORMATIONS OF ERIE AND OHIO BASINS. 



but the latter seems to be of about the same height as the base of the bank. 

 Possibly the bank alone represents the upper beach and the gravel deposits 

 the second beach, but the difference in level appears to be less than is 

 generall}' found between the two beaches. However, only aneroid deter- 

 minations have been made, and the difference may be more than it now 

 seems to be. For 2 or 3 three miles east of Berlin Heights there is a 

 prominent ridge of sandy gravel standing 8 to 10 feet above the tract south 

 of it, and still more above that on the north. This is succeeded toward the 

 east by a cut bank that extends about to Axtel. Along this cut bank there 

 a remarkable number of bowlders, showing, apparently, that the till in 

 which the bank is cut was very stony. From Axtel eastward two ridges 

 ajjpear which differ a few feet in level, and perhaps represent the upper and 

 second beaches. The}* are found both east and west of Vermilion Ri^-er, 

 though they are more closely associated east of the river than west. 



Much of the shore of Lake Maumee from near P^lyria to Cleveland 

 was traced in detail by A. A. Wright, for the Ohio Geological Surve}-.^ 

 The double phase of the shore was clearly brought out both to the west 

 and east of Elyria. Two ridges west of Elyria differing a few feet in level 

 lead southward to the West Branch of Black River, the inner and weaker 

 coming to the river about 3 miles south of the Belmore beach in Elyria, 

 and the outer about 1^ miles farther up the river. The outer ridge is 

 well developed between the West and East branches of Black River, pass- 

 ing Patterson Station and coming to East Black River opposite Laporte. 

 The inner ridge does not appear between these streams, but sets in on the 

 east bluff of East Black River. Both ridges are nearly continuous froin 

 East Black River to Rocky River. The u.pper is known as Butternut and 

 the lower as Cliestnut ridge. They differ 15 to 20 feet in altitude, the 

 upper being in harmony with the upper beach to the west, about 780 to 

 785 feet above tide, and the lower with the second beach, 765 to 770 feet. 

 The upper beach is double for about 3 miles northeast from Laporte, but 

 the two members seem to be nearly identical in level. The upper beach 

 comes to the west bluff of Rocky River near the junction of the two forks 

 of that stream, 3 miles northwest of Berea, and follows nearly the bluff of 

 the stream northeastward for 3 miles, when it crosses to the east side and 

 leads eastward with a curving course convex to the north, past West Park
