National Park Timeline
The history of our National Park system and other federal lands began in 1790 when the District of Columbia was formed. This included what now is part of our park system; the White House, the National Mall, and the National Capital Parks. But it was not until Yellowstone was installed as a National Park on March 1, 1872 that you could truly say that the National Park System was founded. And it was a great founding. The National Park Timeline here will be organized by current park unit, in alphabetical order, and include the dates of formation, and any other changes that may have occurred.
