Zion is Utah's oldest National Park.  In 1909 President Howard Taft named the area a National Monument to protect the canyon under the name of Makuntuweep Monument.  In 1918, the acting director of the National Park Service renamed the Park, Zion, the name used by the Mormons. The US Congress established the monument as a National Park on November 19, 1919. The Kolob section was named a separate Zion National Monument in 1937 and was incorporated into the park in 1956.
