GLACIAL WATERS IN THE LAKE ERIE BASIN 



75 



Several bars occur in the vicinity of Silver Creek. The strongest 

 is over a mile southwest of the village on the 720 foot contour, 

 crossing a north and south road. Other shore features lie cast and 

 northeast of the village, the highest being on the slope of the hill 

 along the 700 foot contour. The lowest crosses the road leading 

 to Irving at about the 600 foot contour. 



North of Farnham 15 miles a faint bar was seen on the east side 

 of Muddy creek at the angles in the road, coincident with the 600 

 foot contour. 



Conspicuous and extensive sand bars occur at Evans village, 

 north of Angola, on the delta of Big Sister and Little Sister creeks 

 [pi. 22]. The road from Evans to the lake along the north side of the 

 creek lies on these bars for nearly 2 miles The south street of the 

 village is on a bar that passes west around the slope. In the village 

 the bars are on the 620 foot contour and lower, while the ridge 

 road is on the 600 foot contour. These teaches belong to the Dana 

 level, and other correlating shore features occur northward on the 

 600-620 foot contours for 4 miles. A strong bar lies north of the 

 road on the west side of Pike creek, near its mouth. 



On the plain west of Eden and Eden Valley are extensive sand 

 tracts and bars much below the Warren level. One leading west 

 from Eden carries a curving road for 2 miles and resembles the 

 Cooper ridge at Hamburg. Somewhat similar phenomena occur 

 at Eden Valley Station, and in both cases they have lower Warren 

 level at the eastern end but decline westward. 



At North Evans there are strong bars on the delta of Eighteenmile 

 creek, which seem to be over 700 feet altitude. The heaviest bar 

 supports the road leading west from the corners, crossing the 

 railroads and then turning south. Another bar lies north of the 

 creek under the highway. 



The strong bar called Cooper ridge, leading west from Hamburg 

 for 4 miles, has been described on page 58. This declines from 

 790 feet altitude at Hamburg to toward 700 feet at the fading 

 western end. It could not have been wholly formed during the 

 life of Lake Warren at the full Warren level, but apparently repre- 

 sents continuous construction in the falling waters. The ridges at 

 Eden and Eden Valley have similar relationship and genesis. 



The east and west ridge at West Seneca, south of Buffalo, sup- 

 posed by Leverett to be a beach [Monogr. XLI p. 772], is amorainal 

 ridge of till with only a thin and patchy veneer of sand. The other 

 ridges and knolls in the vicinity are also till, including the ridge at 

 Ebenezer which is a continuation of the West Seneca Moraine ridge.
