so free from gravel or other normal wave-worn products that a 

 shore line genesis did not suggest itself. In this vicinity, the 

 Cleveland shale bears scarcely a veneer of glacial deposits. 

 Wave action in consecjuence has attacked the shale, and because 

 of the very low slope of the lake basin, cliiT cutting did not take 

 place. The shale was ground off by the waves and piled in a low 

 ridge, so slowly that weathering proceeded, it is thought, to a 

 considerable extent before Maumee Lake fell to a lower level. 



Going south from Warren road, along Brown road, one 

 crosses two other slight gravel and sand ridges which alternate 

 with lagoons. The southernmost of these formed the north 

 shore line of the lagoon bay, already mentioned, which Brown 

 road crosses before reaching Berea road. 



Farther eastward, I have not noted any distinct shore-ridges 

 correlating with this second Maumee level, except the possibility 

 of such a ridge being indicated by the shore gravel extending 

 south-eastward from the intersection of this beach with the West 

 Shore railroad just north of Big creek. The front-slope of the 

 beach along Schaaf road shows some evidence of being modified 

 by the water of this lower level. The Tinkers creek delta has a 

 cliff' and terrace which apparently correlates with it. North- 

 east of Willow, on the slope east of a brick plant, are gravels at 

 the proper altitude. And east of 87th street, between Union 

 avenue and Kinsman road, is another area of possible lower 

 Maumee shore deposits. 



LAKE WHITTLESEY LEVEL. 



The altitude of this shore line is approximately 735 feet, or 

 about 30 feet lower than the preceding stage. From the western 

 border of the Berea quadrangle to the Cuyahoga river, it is 

 practically unbroken, and for the major part of this distance con- 

 sists of a gravel ridge, in a few places one-quarter of a mile 

 wide, enclosing lagoons. The Cleveland, Elyria, and A\'esrern 

 Electric railway enters the Berea sheet on this ridge, but after 

 traversing it for a few rods, swings directly eastward to the shore 

 ridee of the Maumee level.
