The Roosevelt Arch at the North Entrance of Yellowstone National Park was constructed under the supervision of the U.S. Army at Fort Yellowstone, near present-day Gardiner, Montana. The top of the arch is inscribed with a quote from the Organic Act of 1872, which reads "For the Benefit and Enjoyment of the People."
Some people argue that Yellowstone is not just for the Benefit and Enjoyment of Humans; Instead, some beleive Yellowstone represents vital habitat for wildlife. In addition to providing wildlife with a home, National Parks also provides migration routes and breeding grounds for many kinds of animal species. Humans are creating fragmented and developed areas across the country with disregard for the animals that live there too.
