there is evidence of a glacial origin of tlie beach materials; the 

 large number of scattered bowlders along the shore terrace suggest 

 wave-action on lill.

 Shoreline features in vicinity of North Amherst. 



The highway trending to the northeast follows the Whittlesey 

 beach ridge. After crossing the Lake Shore raihvay the ridge is 

 complex, having a lower inland beach. Directly southeast of the 

 "Quarry" a broad cusp was formed (fig. 3). One-half mile south- 

 east of Sheffield Junction the beach contains so much sand that it 

 was drifted Iw the wind into dunes (fig. 2). Just east of this dune 

 area the shore-ridge has a very sharp development as shown by the 

 profiles (fig. 4 F, G) ; the original position of the shoreline here 

 was farther inland as suggested by the long lagoon south of the 

 beach. Thence southward for one-half mile the W'hittlesev level 

 is marked by a cliff cut in the sandstone; beyond this is a gravel 

 and sand ridge which is followed by the "Lake Road" into Elyria. 

 Near the point where the cliff-phase gives place to structural de- 

 posits there are several ridges and intervening lagoons. About 

 one and one-half miles northwest of Elyria, outcropping sandstone 

 again formed a cliff, for about 60 rods, in the \\^hittlesev shore- 

 line.
