Theodore Roosevelt is noted as the founder of the National Parks System and subsequently the founder of one of the greatest American ideas bestowed upon the world. The Theodore Roosevelt National Park, located in North Dakota, was established as a national site in 1946. Before he was president, Roosevelt ventured to the Dakota Territory to hunt bison in 1883. The experience shaped his views on land use and nature conservation, which led to one of the greatest of American ideas: the creation of protected areas as National Parks. During his presidency, the conservation of resources was not necessarily valued for their intrinsic, natural beauty, but it was here in the wilderness that Roosevelt built a ranch and became inspired to campaign toward the preservation of land as parks.
