The Library of Congress website offers a multitude of historical images, many with no known restrictions on use. This image is derived from the 1925 Keystone stereograph titled President Roosevelt and the noted naturalist John Burroughs, at Fort Yellowstone, Yellowstone Park. The first national park in the world, Yellowstone was established in 1872.
John Burroughs was a naturalist and essayist in America whose nature writings, according to some, are eclipsed only by Thoreau's. Burroughs is credited with initiating the Nature Fakers controversy, an intriguing debate in the early 20th century nature writing, that pitted science against anthropomorphism. The debate initially targeted authors telling false stories about animals but later included authors overly sentimental about the natural world.
