BUFFALO SOCIETY OF NATURAE SCIENCES 77 



Just east of the junction of the two State roads south of 

 Water Valley is an island with a strongly marked wave cut cliff 

 on its northern face and a spit on its southeastern side. 



The beach is to be seen east of the road from Armor to 

 North Boston but grows indistinct in its northeastern course 

 towards Orchard Park. Just south of Deuel's Corners is an 

 island. In the southern edge of Orchard Park at the railway 

 bridge is a strong beach which is probably this beach, and the 

 ridge on which is the cemetery is undoubtedly this beach. 



From Orchard Park northeastward to Marilla the beach is 

 indistinct. It is probably represented by the ridge which carries 

 the State Road at the corner of the Jamison Road, southeast of 

 Springbrook, and the gravel beds at the top of the hill on the 

 west side of Buffalo creek at East Elma probably belong to this 

 beach. 



Lake Warren. 



At a level of 40 to 70 feet below the beach of Lake Whit- 

 tlesey a series of beaches and bars marks the level of an extensive 

 glacier front lake which has been designated Lake Warren. 

 This lake was formed by the lowering of the waters of Lake 

 Whittlesey when the receding glacier uncovered an outlet lower 

 than that at Port Huron. The lake covered a strip of Erie 

 county northwest of a line drawn from Versailles to Alden and 

 limited northwardly by the ice front. Westward the lake extended 

 across northern Ohio to a point on the Maumee river west of 

 Toledo, thence north to Bad Axe in the northern end of the 

 southern peninsula of Michigan and thence encircled Saginaw 

 Bay. Its outlet followed the present course of Grand River to 

 Lake Michigan. Eastwardly the lake lay in a narrow strip in 

 the trough along the ice front as far as the present city of Auburn, 

 with long narrow bays extending up the north and south valleys 

 of the Genesee river and the Finger Lakes. 



The shore line character varies at different points. From 

 Versailles to Eden there seems to be but one beach, although 

 immediately west of Cattaraugus creek there are two strongly 

 marked beaches. It passes from Brant Center to Pontiac 

 appearing at Brant on the farm of George Baron as a strong 

 sand ridge.
