GLACIAL WATERS IX THE LAKE ERIE BASIN

ing southeast and east. Northeast of Eden Valley miles the 

 shore line lies around an island hill, with a spit on the southeast. 

 On the east side of the middle branch of Eighteenmilc creek the 

 shore is a conspicuous cliff, curving in a half circle, convex to 

 north, about the high ground on which lies the junction of three 

 towns, and it ends as a bar spit northeast of four-corners, near the 

 main creek. 



The higher Warren carries the main highway all the way from 

 North Collins to Hamburg, about 10 miles. A mile north of North 

 Collins a good bar appears on the east side of the road, but from 

 there to Eden, a stretch of 4 miles, the beach is chiefly a cliff in shale 

 with a smooth slope on the west and no lower Warren level is repre- 

 sented. From Eden. to Hamburg, through Eden Valley, the beach 

 consists of heavy ridges or bars except where cut by streams. 



The lower Warren features are represented on the plain west of 

 Eden and Eden Valley by a complex of bars and sand knolls, 

 some of the stronger bars being followed by the highways. The 

 area is sandy and seems to have been spread with the finer detritus 

 carried into Lake Whittlesey by the glacial drainage from the 

 northeast. The bars and spits which have been noted from the 

 roads are indicated on the map, plate 4. The road winding 

 westward from Eden follows a series of overlapping bars which 

 together form a broad low ridge. Taking the railroad at Eden at 

 788 feet the upper Warren level in the village is 802 feet. At Eden 

 Valley a good bar close to the railroad station is 5 feet higher than 

 the latter, or 783 feet, and is the lower Warren, while the upper 

 Warren at the village east of the creek is about 800 feet. The bars 

 and spits on the plain are at various low levels and decline westward. 

 They were probably formed by the agitation of the waters offshore, 

 and partly during the subsidence of the Warren waters at the 

 extinction of the lake. 



Hamburg stands on the western edge of a delta built in Whittlesey 

 waters by glacial drainage from the northeast and later in Lake 

 Warren by Eighteenmile creek. Running northeast and southwest 

 across the plain is a frontal bar which supports the main streets. 

 In the southwest part of the village the bar has an altitude of 807 

 feet, using the railroad as 789 feet. This is a precise elevation for 

 the upper Warren. 



Hamburg to Spring Brook (Cazenovia valley). In this section 

 the Whittlesey shore line is discontinuous and the fragments are 

 not wholly located. Up the valley of Eighteenmile creek the shore 

 is a cliff north of North Boston along the east side of the highway*
