GEOLOGY OF ERIE COUNTY 



It appears just west of North Collins and carries the State 

 road from that village to Eden Valley and Hamburg. 



At Hamburg it is complicated by delta formations. One 

 strong beach or bar extends westward toward Wanakah from 

 about where the State Road crosses the Erie railway. The main 

 beach passes northeast from Hamburg to Orchard Park, bearing 

 a road as far as Armor. North of Armor it is a well marked 

 ridge as far as Orchard Park. Just north of Orchard Park it 

 crosses the State Road twice, once just on the edge of the village, 

 again at Webster's where it curves into a great fish hook bar.

Fig. 42. The approximate extent of Lake Warren and its outlet to the 

 west. The shores of Lake Warren are indicated by heavy lines, 

 thosi cf our present lakes by faint dotted lines. 



An excellent section of this beach is seen in a gravel pit just east 

 of Webster's. Thence it continues its northeasterly course as a 

 ridge to Springbrook where it crosses Cazenovia creek a mile 

 south of the churches. Thence it continues to Elma Center 

 where it crosses the railway just beyond the station. At Alden 

 two beaches appear. One of these continues to Indian Falls in 

 Genesee county. 



Lake Warren persisted until the glacier had so far receded 

 as to uncover the low lying divide at the headwaters of the 

 Mohawk river. Once these had emerged the waters of Lake 

 Warren abandoned their higher outlet to the westward and 

 drained off down the Mohawk. 



There seem to have been successive stages in the lowering of 

 the lake and successive stands in its level. None of these were 

 of sufficient duration to form great beaches such as characterized 

 their predecessors. Of these stages, one, the most strongly 

 marked, has been named Lake Dana.
