718 GLACIAL FORMATIONS OF EKIE AND OHIO BASINS. 



From West Unity northeastward past Fayette into Michig-an the upper 

 beach lies but a few miles west of the Defiaiice moraine, and parts of 

 that moraine rose above the lake level. It seems to have been protected to 

 a great degree from wave action, and the beach is not so strong as farther 

 south. 



Near Adi-ian traces of a vigorous stream, which was discharged south- 

 ward, were found, as shown by the bedding of its gravel deposits. It pro- 

 duced a remarkable amoimt of erosion considering the fact that it was 

 flowing near the lake level. The west part of the city of Adrian stands on 

 the scourway of this stream, its path being indicated by a level bowlder- 

 strewn sm-face bordered on the west by a definite bank or bluff. Immedi- 

 ately south of the Lake Shore and Michigan Southern Railway a deposit 

 of gravel sets in on this old stream bed and extends for 4 miles to the 

 southwest, or nearl}^ to the village of Sand Creek. The stream seems to 

 have entered Lake Maumee near this village, for southwest of Sand 

 Creek, along the west side of the Defiance moraine there is a sandy ridge 

 at a level corresponding to the upper beach of Lake Maumee. It appears 

 north of Black Creek near Packer ^ and south of Black Creek from near 

 Bimo to the vicinity of the State line, passing about a mile east of Morenci. 

 It is a low ridge only 3 to 5 feet high, but is perhaps as strong as could be 

 expected along a nan-ow bay. The west border of the bay can be traced 

 easily from Sand Creek southwestward by a cut bank. 



At the time the stream was operating, the ice sheet seems to have 

 occupied the Defiance moraine, so that Lake Maumee extended but little 

 north of the Ohio-Michigan State line. The production of this moraine, 

 however, as already indicated, occupied only a part of the time when Lake 

 Maumee was forming its upper beach. The beach has been found farther 

 north on the inner border of that moraine. 



The southernmost point on the inner slope of the northern limb of the 

 Defiance moraine at which the upper beach has been identified is near 

 Fail-field, Mich., 6 miles south of Adrian, but there are probably traces of 

 it farther south in the midst of the sand area of northern Fulton County, 

 Ohio, for parts of that area rise 20 feet or more above the level of the upper 

 beach of Lake Maumee. The second beach is well developed at many points 

 both on the east and west borders of that sand area, as indicated below. 

 About a mile southwest of Fairfield a g-ravel ridg-e sets in which leads
