Travelling westward from E-Town, we mount the enclosing slope of the Pleasant Valley, and through the gorge alongside Mount Hurricane, up the canyon of the western branch of Bouquet River. Crossing the summit among the granite rocks and forests, we then descend into another long, trough-like valley, stretching as a broad intervale far away both north and south, through which flows Ausable River. This intervale includes the charming "Flats of Keene," the sparkling Ausable waters meandering quietly over them beneath overhanging maples and alders, quivering aspens and gracefully swaying elms, occasionally dancing among the stones and shingle in some gentle rapid. Here are farmhouses, with many villas, the great mountain ridges protecting the valley from the wintry blasts. This intervale has in the eastern ridge the Giant of the Valley, with Mount Dix alongside, rising nearly five thousand feet, and to the southward, reared thirty-five hundred feet, exactly at the meridian, is the graceful Noon Mark Mountain, which casts the sun's noon shadow northward over the centre of the "Flats of Keene." The river, coming from the south, flows out of the lower Ausable Lake or the Long Pond, and dashes swiftly down its boulder-covered bed. Its waters are gathered largely from the eastern flanks of Mount Tahawus, and also from the galaxy of attendant peaks--Dix, Noon Mark, Colvin, Boreas, the Gothics, and others--grandly encircling the southern head of the attractive Keene Valley. The Ausable River rises under the brow of Tahawus, and flowing through the two long and narrow Ausable Lakes at two thousand feet elevation, traverses the whole length of the Keene Valley northward, to unite with its western branch at Ausable Forks, and thence goes through the great chasm to Lake Champlain. The head of the Keene Valley with the adjacent mountain slopes, extending through parts of three counties and covering a tract of forty square miles, is the "Adirondack Mountain Reserve." This reservation gives complete protection to the fish and game, and also preserves the forests and sources of the water supply. The Lower Ausable Lake is about two miles long and the Upper Ausable Lake nearly the same length, there being over a mile's distance between them. Some of the highest and most romantic of the Adirondack peaks environ these lakes. The sharply-cut summit of Mount Colvin rises forty-one hundred and fifty feet alongside them. The Ausable Lakes are in the bottom of a deep cleft between these great mountains, their sides rising almost sheer, two thousand feet and more above them. The lake shores are steep and rocky walls, reared apparently to the sky, the deep and contracted cleft making the lakes look more like rivers, surmounted high up the rocks by overhanging foliage, the trees diminutive in the distance. Of the Upper Ausable Lake, Warner writes that "In the sweep of its wooded shores, and the lovely contour of the lofty mountains that guard it,
