[Vol. XIII 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. FUj. S.

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 Loc. cit., p.
