Anderson’s climb was the beginning of a search for routes to prominent heights in Yosemite that continues today. The fame of Yosemite’s wonders was spreading through the world, and the advent of stage roads brought a multitude of visitors who preferred to see the region without having to drill to do so. It was imperative that officials in charge of the state reservation improve and multiply the faint Indian trails in order that eager visitors might reach the valley rim and the High Sierra beyond. Because appropriations made by the state legislature for the use of the Yosemite Valley Commission were too small to enable that executive body to undertake a program of trail building, toll privileges were granted to certain responsible individuals in return for the construction of some of the much-needed trails. Albert Snow, John Conway, James McCauley, Washburn and McCready, and James Hutchings were prominent in this contractual arrangement with the Yosemite commissioners. Two trails antedate the regime of the Yosemite Valley Commissioners—the trail to Mirror Lake and the Vernal Fall Trail. No record exists identifying the builders of these pioneer trails. Albert Snow, 1870, built a horse trail from “Register Rock” on the Vernal Fall Trail, via Clark Point, to his “La Casa Nevada” on the flat between Vernal and Nevada falls. In 1871, John Conway, working for McCauley, started construction of the Four Mile Trail from the base of Sentinel Rock to Glacier Point. The project was completed in 1872. The old Mono Trail of the Indians between Little Yosemite and Glacier Point was followed by Washburn and McCready when they constructed their toll route here in 1872. In 1874, James Hutchings met the cost of a horse trail up Indian Canyon, which by 1877 already had fallen into such disrepair as to make it accessible only to hikers. The disintegration progressed rapidly, and the “improved” aboriginal route to the north rim found use during a comparatively few years of Yosemite tourist travel. Geographically and topographically it has much to commend it; in the current master plan of Yosemite National Park it is carried as the trail proposal calculated “to provide the best all-year access to the upper country on the north side of the valley.” Early action is expected which will place it on the map again. The Yosemite Falls Trail, started by John Conway in 1873 and completed to the north rim in 1877, was carried by its builder and owner still higher to the summit of Eagle Peak, highest of the Three Brothers. John Conway’s homemade surveying instruments used in trail building are preserved in the Yosemite Museum.
