The wagon-road from Mount Washington summit down to the base, is on the eastern side, and is a little more than eight miles long, with an average gradient of one to eight, descending into the Glen and displaying magnificent views. The descent occupies about one hour, and the ascent five hours. On the southeastern side of the mountain is Tuckerman's Ravine, a huge gorge enclosed by rocky walls a thousand feet high. This ravine usually displays the "Snow Arch" until late in August, formed by a stream flowing out from under the huge masses of snow piled up in winter, until it gradually melts away and collapses. The main Glen is formed by the deep and thickly-wooded Pinkham Notch at the eastern base of Mount Washington, its floor being at two thousand feet elevation, and this Notch continues north and south in deeply-carved stream beds, the Peabody River flowing northward to the Androscoggin at Gorham and the Ellis River southward to the Saco. The Peabody descends rapidly to the Androscoggin, entering it at about eight hundred feet elevation, the active town of Gorham being located here in a beautiful situation, and having two thousand people, at the northern gateway to the White Mountains. The Androscoggin, having drained the eastern mountain slopes, flows away into the State of Maine to seek the Kennebec, and thence the sea. In the Glen, in the coaching days, the old Glen House was the headquarters at the foot of the road down Mount Washington, but it was burnt in 1894, and has not been rebuilt. To the eastward, bounding the Glen, rise the Wild Cat Ridge and the impressive Carter Dome, which would be a grand mountain elsewhere, but here is dwarfed by the overshadowing Presidential range on the western side. From the Pinkham Notch the little Ellis River goes southward, and below the outlet of Tuckerman's Ravine is the beautiful Crystal Cascade, where it pours down eighty feet over successive step-like terraces. Another lovely cataract it makes is the Glen Ellis Fall, which is considered the finest in the White Mountains, on the slope of the Wild Cat Ridge. The stream slides down an inclined plane of twenty feet over ledges, and then falls seventy feet through a deep groove, twisted by bulges in the rocks and making almost a complete turn. Thus sliding, foaming and falling, the stream leaps nearly a hundred feet into a dark green pool beneath. The Glen broadens as it progresses southward, and soon becomes a widened intervale, having many houses for summer boarders. [Illustration: _Log Bridge over the Wild Cat, near Jackson, N. H._]
