Yellowstone National Park:
Its Exploration and Establishment
Part III: The Park Movement
Liberty Cap and Clematis Gulch, from an
original water color by Thomas Moran, 1871.
The increased knowledge resulting from
definitive exploration of the Yellowstone region spawned a park
movement which led directly to establishment of Yellowstone
National Park by the Act of Congress signed into law on March 1,
1872. This was the first reservation of wild lands for recreational
purposes under the direct management of the Federal government.
