 for over two miles. 



Just west of the Berea sheet in Lorain county, the Warren 

 shore bears sharply to the north. This point of land extending 

 into the lake acted as a wind break to the shore directly east. 

 In consequence of this, the first two miles of the Warren shore 

 on the Berea sheet consists almost entirely of sand and very fine 

 gravel; the beach contains a slight terrace (fig. 3, K), a cliff that 

 averages about 20 feet, and for the most of this distance, is a low 

 ridge. A few rods east of the north-south road connecting West 

 Dover and Bement. the Warren level is marked bv a cliff cut in

 more than four miles. Contemporaneously with the c|evelop- 

 ment of the first mile of this cliff, off-shore deposits gradually 

 widened the beach; throughout part of this distance, two or more 

 barriers developed, giving rise to intervening depressed areas 

 where marshes have persisted till the present time. A cliff and 

 terrace characterizes this shore where it crosses the buried Rockv 



Between the sandy beach on the west side of the sheet and 

 the till terrace marking the site of old Rocky river, the interval 

 of shales bears locally a few feet of glacial drift. Eastward of
