the park here, dating from 1947, is named in honour of a president who during his time in office (1901-09) established the US Forest Service, signed the 1906 Antiquities Act, and working with Congress established 5 national parks, 150 national forests, and dozens of federal reserves....his initiative spawned the large amount of protected lands now so valuable to Americans, and many international visitors...Roosevelt himself spent a lot of time in North Dakota, and from those experiences sprang the impetus for his ground-breaking contributions to environmental conservation
