CaliGun 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 ridge becomes composite, in- 

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

 oped from this beach, extends northward from Detroit street 

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

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

 rods in width. Near 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 indicated by a wide sandy beach, in places, 

 reaching from Detroit avenue southward to Franklin avenue. 



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

 west of W^ade Park, the Warren 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 U^niver- 

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

 ward as far as Collamef, 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 cliff'-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 building 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 Nottingham. For three-fourths of a 

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

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