The National Park Service, (NPS), began in 1872 as the United States National Park System from a single reservation known as Yellowstone National Park.

The actual National Park Service began as the brainchild of Theodore Roosevelt who during his Presidency annexed 5 national parks. He also broadened the Antiquities Act of 1906 enabling succeeding Presidents to annex other landmarks and historical structures as national monuments.

The National Park Service is one of Theodore Roosevelt’s strongest legacy. He was honored as one of the faces gracing The Mount Rushmore National Park. He is known as the greatest conservationist president.
