with Raised Beaches of Lake Erie. 295 



There is outside of these beach ridges a peculiar ridge which 

 appears to be a compromise between a beach and a moraine. 

 At its western end, near the inner bend of a tributary of Big 

 creek, a mile or so west of North Linndale, it is composed of 

 gravel and resembles in every way the beaches just north of it, 

 but upon tracing it eastward the gravel changes to till, giving 

 it the appearance of a low glacial ridge. This low till ridge 

 may be traced through North Linndale to the bluff of Big 

 creek near the bend of that stream, and upon crossing the 

 creek we find a much larger ridge. of till, one worthy the 

 name moraine. This large ridge is separated from the eastern 

 end of the beach proper by the narrow valley of Big creek, 

 one fourth mile or less in width. I was unable to find beach 

 gravel along the inner (north) slope of the morainic ridge 

 farther east than the terminus of the beach ridge, but this 

 inner border district is very flat and its clays contain few peb- 

 bles compared with the clays of the moraine. These features 

 apparently indicate that the lake water covered the tract north 

 of the moraine, either while the ice overhung it or subse- 

 quently. 



From Newburg northward to the Garfield Monument there 

 are two terraces along the east bluff of the Cuyahoga, which 

 may possibly be correlated with the Leipsic and Belmore 

 beaches. It is however doubtful if the correlation of the 

 upper terrace with the Lei23sic beach is legitimate, since the 

 terrace stands slightly higher than the beach at its eastern 

 terminus in North Linndale, being 210-220 feet above Lake 

 Erie as determined by Dr. Newberry,* while the Leipsic beach 

 is but 196 feet. Dr. Newberry recognized the difficulty of 

 making this correlation and suggested that the lower terrace 

 which stands 165-170 feet above Lake Erie, is the correlative 

 of the upper beach at North Linndale, " since a terrace is cut 

 by shore waves somewhat below the water level, while on a 

 gently inclined surface of loose material the waves raise a 

 beach above the water" (p. 182). My examination of the 

 upper terrace failed to disclose beach deposits on it or other 

 decisive evidence that it was occupied by the lake, but the 

 decision as to whether or not it is a lake terrace should be left 

 to one more familiar than I with the various phases such ter- 

 races may present. Dr. Newberry suggests that the upper 

 terrace may find its correlative west of the Cuyahoga in some 

 undiscovered shore line south of the Leipsic beach, but since, 

 as previously stated, the districts south of the beach do not 

 afford distinct evidence of any such shore line, this view does
