(<\ iIk' ice. About a mile iiorlli of Willow along the Warren 

 road, there is beach gravel, and north of Kingsbury run the rock 

 slope appears to be wave-cut at an altitude correlating with this 

 lake stage. 



Returning to the western edge of the Berea sheet, we find a 

 few rods north of this shore line what was probably a barrier. 

 and later a beach, followed now by a highway, locally designated 

 "Chestnut ridge." This ridge is about 15 feet below the shore 

 line above described ; it consists generally of fine sand ; is from 4 

 to 6 rods wide and rises 8 feet on the average along its front- 

 slope, which is very gradual (fig. 2, F, G). Between Chestnut 

 ridge and the beach of the higher Maumee level, the interval is 

 verv muckv, indicating a former lagoon condition ; to the east and 

 north, this ridge blends gradually into the general level. Be- 

 tween this ]joint and Xorth Olmsted, two slender ridges, tied at 

 their western ends to the beach of the higher level, trend with the 

 old shore line. 



From Xorth Olmsted to the edge of the present river chan- 

 nel directlv west of Kamms. is a sharply defined beach slope 

 changing locally into a constructed shore ridge. Throughout 

 this distance we have the permanent shore line for the lower 

 Maumee level (indicated by 2 on fig. i ). marking the position of 

 the water after the Rocky river embayment had been completely 

 closed ; the back slope of the ridge descends into extensive mucky 

 areas which indicate the swampy condition that prevailed for a 

 long period after the embayment had been shut ofY. Market- 

 gardening is the chief industry in this section at the present time. 

 The most conspicuous spit developed in the process of enclosing 

 the Rocky river embayment is the broad-based ridge extending 

 southward from Goldwood ; opposite the end of this, extending 

 northwestward from the other shore of the bay. is a correlating 

 spit ; apparently the two approached quite closely but have since 

 been separated by erosion. 



Proceeding eastward from Gokhvood this shore line takes 

 on more and more the form of a constructed beach, varying in 

 width from 4 to 15 rods, and in height from 12 to 24 feet. Near 

 lhe river it is slightly modified through erosion.
