The Abandoned Shorelines of the Oherlin Ouadrangh\ Ohio 105 



Butternut Ridg-e and is less than half a mile distant, represents 

 the lower Alaumee level. It has a slighter development, and con- 

 sists of finer deposits; eight feet is the usual height (fig. i C). 

 Its western end shows successive positions due to the development 

 of spits into the deepening- waters of the bay. Many lagoons for- 

 merly existed between Butternut and Chestnut Ridges. 



Between the two branches of the river I was unable to locate 

 a continuous shoreline of the lower Maumee; it is represented by 

 only one short ridge, consisting mostly of weathered clay, wave- 

 eroded from the subjacent shale, directly south of Elyria. 



Sugar Ridge is obviously an off-shore barrier of the lower 

 Maumee stage. It has a symmetrical development (fig. i D, E) 

 and, from the numerous bowlders, particularly along its eastern 

 half, I infer that the barrier may have been initiated by an irregular 

 deposit of glacial drift. 



Extending northward from a point near the middle of Murray 

 Ridge I have mapped a structure which resembles a barrier through 

 part of its course ; elsewhere its strength of development implies a 

 regular shoreline. This inference is based partly on other Maumee 

 deposits directly north, deposits which indicate this level declined 

 gradually, thus converting part of the barrier int(3 a beach.
