Elsewhere throus^h these valleys it constitutes their flood plains 

 so far as may be observed in the old terraces, in the erosion of 

 the laterals crossing the flood plains, and in the notch made by the 

 present major streams traversing them. The further distribution 

 of washed drift in this part of the State has been described by 

 Leverett.^ 



In topography the drift of this region presents some interest- 

 ing features. Near the western edge of the area, just off^ the map 

 (Fig. 3) in Madison Township, the moraine is quite kame-like. 

 The low place now crossed by the Rocky Fork (Fig. 8) is due in

 slope on the right is rock which lies within the Y-shaped gap at Hanover (p.l41). 

 The sky line is the north wall of the "Newark River" valley ; the stream in the 

 foreground is the Rocky Fork. 



part to the removal of the drift by the augmented drainage from 

 the ice-front north and west; this stream has terraced the drift 

 east of the highway, thus possibly over-steepening the sloi)e there, 

 but the low sag is the result rather of rapid melting of the ice- 

 tongue. 



Proceeding eastward the highway rises about KM) feet, then 

 crosses a level delta-like stretch of drift. The surface is mildly
