Cahoun creek, there is slight evidence of gravel accumulations at 

 the base of the bluff. 



Commencing- three- fourths of a mile west of Rocky river, 

 the top of the bluff" bears a beach ridge, its crest rising three to 

 four feet. Xearing the river, the ridg^e becomes composite, in- 

 closing lagoons. Directly east of Rocky river, a cusp, devel- 

 oped from this beach, extends northward from Detroit street 

 across the Xickel Plate railroad. For about two miles this beach 

 consists of a sand ridge locally composite, and from 40 to 80 

 rods in width. Xear Highland avenue, the beach gravels present 

 a sharper front slope (fig. 3, L). Just east of this avenue, the 

 shore line swings slightly southward, changing to a cliff' cut in 

 the Cleveland shales. In the vicinity of West looth street, the 

 Warren level is again iuflicated by a wide sand}- beach, in places, 

 reaching from Detroit avenue southward to Franklin avenue. 



On the east side of the Cuyahoga, excepting about one mile 

 west of A\'ade Fark, the AV'arren level is marked by the Euclid 

 avenue beach. From the vicinity of East 65th street, to the 

 campus of the Women's College of Western Reserve Univer- 

 sity, the Warren shore is found north of Euclid avenue. East- 

 ward as far as Collamer. a beach-ridge condition continues to the 

 eastern edge of Euclid sheet. There is evidence that the War- 

 ren level did some wave-cutting in the shales, developing a 

 gravel-bordered terrace that is wider in some places than in 

 others, the control being a matter of stratigraphy. East of 

 Euclid, the clift'-cutting work of this lake was more pronounced. 



In the vicinity of the intersection of Ansel road and Super- 

 ior avenue, I noted a conspicuous development of rather fine 

 sand. Sand of the same level may exist westward, but on ac- 

 count of extensive btiilding operations, tracing it was not at all 

 satisfactory. Eastward from Doan creek, however, this broad, 

 low ridge of sand may be followed without a break to the inter- 

 section of Penobscot and St. Clair avenues ; from this point east- 

 ward, St. Clair avenue is located on this ridge of sand and gravel, 

 and continues thereon to Xottingham. For three-fourths of a 

 mile east of Xottinghaiu, the gravel ridge is but slightly devel- 

 oped, but reappears again just before St. Clair avenue crosses the
