This 10-acre park includes some of the oldest buildings in Arizona. Now operated by the Yuma Crossing National Heritage Area; also the home of the Yuma Visitors Bureau Visitor Information Center. Bike rentals are available here.
For nearly 20 years beginning in 1864, all the military posts in the Southwest traced their lifelines to the Yuma Quartermaster Depot.
Here 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.
With the coming of the railroad in 1877, the Depot's supply role faded and the Army closed it in 1883. But the site lived on as a telegraph and weather station and customs office - and then as the first home of the Bureau of Reclamation (U.S. Reclamation Service) and the Yuma County Water Users Association. Engineering pioneers worked from here to tame the river, building dams to prevent floods, generate power and ensure a source of water.
Don’t miss the exhibit on the Yuma Siphon - a massive tunnel under the Colorado River that first delivered irrigation water to the Yuma Valley in 1912, and still operates today, right next to the park.
