This film “Yosemite” was produced by Encyclopedia Britannica Films Inc., which was the top producer and distributor of educational films between the 1940s and 1990s. This film is based on a film produced by Atwater Kent Foundation for the National Park Service, Department of the Interior with photography by Ted Phillips, A.S.C, and covers the historical formation of Yosemite National Park from swampy lowland to high mountain peaks and deep river canyons. (Note: this print was formerly owned by the The United States of Agriculture, Bureau of Animal Industry Pathological Division, and has that organization’s logo at the head.)
