Any description of the glories of the John Muir Trail from its entrance into the park to its climax upon the summit of Mount Whitney far passes the limits of a chapter. In time it will inspire a literature. Approaching from Yosemite through the canyon of the San Joaquin, the traveller swings around the north side of Mount Goddard, crosses gorgeous Muir Pass, and enters the fringe of cirques and lakes which borders the western edge of Sierra's crest from end to end. Through this he winds his way southward, skirting lakes, crossing snow-fields, encircling templed cirques, plunging into canyons, climbing divides, rounding gigantic peaks, surprising views of sublimity, mounting ever higher until he stands upon the shoulders of Mount Whitney. Dismounting here, he scrambles up the few hundred feet of stiff climb which places him on the summit, from which he looks out north, west, and south over the most diversified high mountain landscape in America, and eastward over the Sierra foothills to Death Valley, lowest land in the United States. No thrilling Alpine feat is the ascent of our loftiest summit. But those who want to measure human strength and skill in terms of perpendicular granite may find among Whitney's neighbors peaks which will present harder problems than those offered abroad, peaks which themselves well may become as celebrated in future years. The John Muir Trail is destined to a fame and a use perhaps many times as great as those men thought who conceived it as a memorial to a lover of the trail, and of all that that implies. It will play a distinguished part in the education of the nation in the love of mountains. It will win artists to a phase of the sublime in America which they have overlooked. It will bring students to the classrooms where Nature displays her most tremendous exhibits. Nevertheless, Roosevelt's lower levels will draw many times as many devotees as will the High Sierra; and these visitors will stay longer. It is the valleys and the canyons which will prove the greatest lure, for here one may camp leisurely and in entire comfort, and thence make what trips he chooses into the regions of the peaks and the cirques. There are literally thousands of canyons and of many kinds. Besides the Kern Canyon there are two which must rank with Yosemite. In the summer of 1916 I travelled the length of the park, as far as the Giant Forest, with a party led by Director Stephen T. Mather, of the National Park Service, then Assistant to the Secretary of the Interior, and was powerfully impressed with the scenic qualities of the Tehipite Valley, and the Kings River Canyon, at that time little known.
