Most of these ravines show the characteristic trough-form of glaciated valleys, but the example par excellence in the White Mountains is Crawford Notch (Fig. 7), which for true charm of outline can hardly be equaled even in the well known glaciated mountains. In the Adirondack Mountains Lake George lies on the floor of a glaciated trough of superb beauty (Fig. 23) and several of the finger lakes of western New York occupy similar valleys of rounded profile. In developing the subject of continental glaciation the teacher refers to the terminal moraine (Fig. 8) with its characteristic knob and kettle. Fig. 9.—The largest erratic on Long Island and one of the largest in the eastern United States It is a mass of crystalline rock carried in the ice sheet from New England over Long Island Sound topography so easy of access on Staten Island, its continuation across the "Narrows" into Prospect Park, Brooklyn, its bifurcation further east where two terminal moraines form the backbone of Long Island and its fish-like tail at its eastern end, and then on into Block Island, Nantucket, and Marthas Vineyard. Westward in New Jersey it may be seen in rather classic perfection at Plainfield and at Hackettstown. The lobate form of the ice front is shown by the festoon-like trend of the moraine in New Jersey (Fig. 29) and in Marthas Vineyard. Then there is the great outwash plain fringing the southern side of Long Island and the islands to the east. The city of Plainfield, New Jersey, stands upon such a plain, whence it derives its name. The contrast between glaciated and non-glaciated areas, the difference in soil, the disturbed drainage, the rapids and waterfalls and numerous lakes in one case, their.
