The major difference between a national park and a national monument is the manner in which they are created. A national park is established through an Act of Congress, and the land may originate from a variety of sources, including public and private land. A national monument is established by Presidential proclamation, and this land is to be taken only from existing public (federal) ownership.
Organ Pipe National Monument is about a 2 hour drive from Tucson. Some quick facts. The park was established in 1 937 Franklin D. Roosevelt. Most of the mountains in the monument are volcanic in origin in the Ajo range. The highest peak in this range, as well as in the park, is Mt. Ajo, which elevates to a height of 4,808 feet.
