Colorado River State Historic Park

The Colorado River State Historic Park is located on a portion of the grounds of the old U.S. Army Quartermaster Depot (QMD) established in 1864. For nearly 20 years, all the military posts in the Southwest traced their lifelines to the Yuma Quartermaster Depot. On the high ground above the Colorado River, the U.S. Army’s warehouses held a six-month supply of clothing, food, ammunition and other goods for forts in Arizona, Nevada, Utah, New Mexico and Texas – and were surrounded by as many as 900 mules and their teamsters. This beautiful 10-acre park includes five buildings dating back to the Depot’s earliest days – among the oldest and best-preserved buildings in the state of Arizona.
