In 1960, a bobcat was killed by a car near Squaw Lake (now Indian Pond) on the north shore of Yellowstone Lake; its skull was deposited in the Yellowstone Museum collection. Yellowstone has many rock outcrops, canyons bordered by rock ledges, conifer forests, and semi-open areas that seem to offer conditions favorable for bobcats—adequate shelter, a variety of rodents, rabbits, hares, birds, and other small animals as well as seasonal carrion, for food. Biologists studying the lynx in Yellowstone believe it has persisted in the park in some number since the park's creation in 1872.

Yellowstone is one the largest National Parks and there was so much information about the park that two posts were needed to cover all the information. Subsequent protection from hunting and wolf control programs may have contributed to increased numbers but suppression of forest fires probably was the most important factor, since moose here depend on mature fir forests for winter survival.
