significantly reduced travel time to Yosemite Valley from Wawona. The famous Tunnel View is on the valley side of the tunnel and Old Inspiration Point is above it. A flood, reduced lumber and mining extraction, and greatly increased automobile and bus use forced the Yosemite Valley Railway out of business in 1945. The present day Tioga Road, now part of California State Route 120, was dedicated in 1961. Interpretive programs and services for national parks were pioneered in Yosemite by Harold C. Bryant and Loye Holmes Miller in 1920. Ansel F. Hall became the first park naturalist in 1921 and served in that role for two years. Hall's idea to have park museums act as public contact centers for interpretive programs became a model followed by other national parks in the United States and internationally. Yosemite Museum, the first permanent museum in the National Park System, was completed in 1926. The Ahwahnee Hotel, in Yosemite Valley, is a National Historic Landmark. Built in 1927, it is a luxury hotel designed by the architect Gilbert Stanley Underwood, decorated in Native American motifs. For many years it hosted an annual pageant produced by Ansel Adams. During World War II it was used as a rehabilitation hospital for soldiers. Restoration and preservation Large floods covered Yosemite Valley in 1937, 1950, 1955, and 1997. These floods had a flow rate of 22,000 to 25,000 cubic feet (620 to 700 m3) per second, as measured at the Pohono Bridge gauging station in Yosemite Valley. All the structures in Old Yosemite Village, except for the chapel, were either moved to the Pioneer Yosemite History center in Wawona or demolished during the 1950s and 1960s. Other structures in the park were also moved to the history center. Cedar Cottage, the oldest building in Yosemite Valley, was demolished in 1941 along with others, even though they had not been flooded. Little regard was given to historic preservation, as the priority was thought to be the preservation and restoration of natural scenery. Congress set aside about 89 percent of the park in a highly protected wilderness area through passage of the Wilderness Act of 1964. No roads, motorized vehicles (except rescue helicopters and other emergency vehicles), or any development beyond trail maintenance are allowed in this area. The adjacent Ansel Adams Wilderness and John Muir Wilderness were also protected under the act and include regions removed from the park
