As was true of Mather and Albright, succeeding directors of the National Park Service have taken personal interest and active part in the management of Yosemite National Park. On July 17, 1933, Arno B. Cammerer, formerly Associate Director, succeeded Albright in the Washington post. During his incumbency, 1933-1940, the national park system increased from 128 areas to 204 units, and in addition to regular appropriations, nearly 200 million dollars was expended by the Service in connection with the programs of the Civilian Conservation Corps, the Public Works Administration, and the Emergency Relief Appropriation acts. Under Cammerer’s directorship, five C.C.C. camps were established in Yosemite National Park. With the help of C.C.C., C.W.A., and P.W.A., many management and construction projects in the park were advanced far ahead of regular schedule. The Wawona Road tunnel project was completed, and notable progress was made in constructing the Tioga and Big Oak Flat roads on modern standards. Winter use of the park increased mightily, and the Yosemite Park and Curry Company developed the Badger Pass ski center in accordance with Service plans. Because of failing health, Cammerer resigned as Director in 1940, and Newton B. Drury, a Californian and a member of the Yosemite Advisory Board, was appointed to the position on June 19, 1940. Since 1919, Drury had been a leader in the movement to preserve distinctive areas for park purposes. As executive head of the Save-the-Redwoods League, he had become a nationally recognized authority on park and conservation affairs and was intimately acquainted with the problems of Yosemite National Park through personal study. The normal problems of the park and of the Service, generally, were greatly complicated by the circumstances resulting from World War II, and the years 1942-1945 were probably the most critical in the history of national parks. But in spite of pressure exerted by production interests and those who sought to capitalize on the park’s assets under the guise of “war necessity,” the natural values of Yosemite were held inviolate. And it is to the everlasting credit of Director Drury and his staff and associates in central offices and the field that during the years of all-out warfare serious inroads were nowhere made upon national park values. Each year, more than a half million people benefit by the great park’s offerings, and each year witnesses new demands for expansion of public utilities provided by the operators and the Government. To meet these demands and at the same time guarantee “benefit and enjoyment” of Yosemite values for future generations of visitors is one of the most exacting tasks engaged in by public servants anywhere.
