These objectives in almost every particular are also the objectives of the Naturalist Department of Yosemite National Park. In 1937 the Congress authorized park naturalists and other government employees to devote their regular working hours to the program of the Yosemite Natural History Association and similar “coöperating societies” in national parks which might be designated by the Secretary of the Interior. In effect, the Yosemite Natural History Association is an auxiliary of the naturalist department. For nearly twenty-five years it has adhered to its defined purposes, and the support it has given to the interpretive program has furthered research in the park, enriched the collections of the Yosemite Museum, and promoted the dissemination of the Yosemite story. The function of the interpreters has been, and their purpose must be, to enrich the mountain experience of the Yosemite traveler and thereby demonstrate that a national park is far more than a tourist’s way station. Upon today’s visitor and his full awareness of national-park values the future of the national-park concept must depend. A public which, in its enjoyment of the parks, comprehends the importance of “the scenery and the natural and historic objects and the wildlife therein” will insist that they remain unimpaired. CHAPTER XI _GUARDIANS OF THE SCENE_ In the body of Indian fighters who first entered Yosemite Valley, there appears to have been but one man who sensed the possibilities of public good to be derived from the amazing place just discovered. A year prior to the entry of the Mariposa Battalion, L. H. Bunnell, in climbing the trail from Ridley’s Ferry (Bagby) to Bear Valley, had descried in the eastern mountains an immense cliff which, apparently, loomed, column-like, to the very summit of the range. He looked upon the “awe-inspiring sight with wonder and admiration, and turned from it with reluctance to resume the search for coveted gold.” When, on March 25, 1851, Bunnell stood at Inspiration Point with other members of Savage’s command and gazed upon the extravagance of natural wonders, he recognized “the immensity of rock” which had, the previous year, astonished him from afar. He writes: Haze hung over the valley—light as gossamer—and clouds partially dimmed the higher cliffs and mountains. This obscurity of vision but increased the awe with which I beheld it, and as I looked, a peculiar exalted sensation seemed to fill my whole being, and I found my eyes in tears with emotion. He withdrew from the trail and stationed himself on a projecting rock, where he might contemplate all that was spread before him. Major Savage, bringing up the rear of the column, brought him out of his soliloquy in time to join the battalion in its descent to the floor of the valley.
