A road to Glacier Point was completed in 1882 by John Conway, and the Great Sierra Wagon Road was opened in 1883, which roughly followed the Mono Trail to Tuolumne Meadows. Clark and the sitting commissioners were removed from office by the California Legislature in 1880, and Hutchings became the new guardian. Hutchings in turn was replaced as guardian, in 1884, by W. E. Dennison. Clark was reappointed as guardian in 1889 and retired in 1896. In 1900, Oliver Lippincott became the first to drive an automobile into Yosemite Valley. Yosemite Valley Railroad, nicknamed "the short line to paradise," arrived at nearby El Portal, California in 1907. Numerous hiking and horse trails were cleared, including a walking path through Mariposa Grove. Concessionaires Yosemite's first concession was established in 1884 when Mr. and Mrs. John Degnan established a bakery and store. The Desmond Park Service Company was granted a twenty-year concession in 1916; the company bought out or built hotels, stores, camps, a dairy, a garage, and other park services. Desmond changed its name to the Yosemite National Park Company in December 1917 and was reorganized in 1920. The Curry Company was started by David and Jenny Curry in 1899; the couple also founded Camp Curry, now known as Curry Village. The Currys lobbied reluctant park supervisors to allow expansion of concessionaire operations and development in the area. Administrators in the National Park Service felt that limiting the number of concessionaires in each national park would be more financially sound. The Curry Company and its rival, the Yosemite National Park Company, were forced to merge in 1925 to form the Yosemite Park & Curry Company (YP&CC). National park John Muir's influence Immediately following his arrival in California in March 1868, naturalist John Muir set out for the Yosemite area, where he found work tending to the sheep owned by a local rancher, Pat Delaney. Muir's employment provided him with the opportunity to study the area's plants, rocks, and animals; the articles and scientific papers he wrote describing his observations helped to popularize the area and to increase scientific interest in it. Muir was one of the first to suggest that Yosemite Valley's major landforms were created by large alpine glaciers, contradicting the view of established scientists such as Josiah Whitney, who regarded Muir as an amateur. Alarmed by over grazing of meadows, logging of giant sequoia, and other damage, Muir changed
