Agua Fria National Monument is in the U.S. state of Arizona, approximately 40 miles north of downtown Phoenix, Arizona. Created by Presidential proclamation on January 11, 2000, the 72,344-acre monument is managed by the Bureau of Land Management, an agency within the U.S. Department of the Interior. The Bureau of Land Management already managed the lands; however, under monument status the level of protection and preservation of resources within the new monument have been enhanced.
The monument is a unit of the BLM's National Landscape Conservation System. Over 450 distinct Native American structures have been recorded in the monument, some of large pueblos containing more than 100 rooms each. The enhanced protection status also provides greater habitat protection for the numerous plant and animal communities.
