Woodrow Wilson signed the act that created the National Park Service in 1918 for the Department of the Interior. The first park actually was created though in 1872 – Yellowstone, and it resided under a different service until 1933 an Executive Order established acquiring parks and military sites from the Forest Service and the War Department. Today the service now comprises over 400 locations. Happy Birthday!
