Yuma Quartermaster Depot State Historic Park (Colorado River State Historic Park) | Yuma

Yuma Quartermaster Depot State Historic Park – In Detail

The Yuma Quartermaster Depot State Historic Park, formerly known as the Colorado River State Historic Park, is a historically significant site that served as a crucial military supply hub in the 19th century. Located in downtown Yuma, Arizona, on the banks of the Colorado River, this well-preserved site offers a comprehensive look at military logistics, river commerce, desert survival, and governmental infrastructure during the Arizona Territory era.

🏞️ Historical Background

Established in 1864, the depot was one of several quartermaster depots established by the U.S. Army across the western frontier. Its primary purpose was to store and distribute military supplies-including food, ammunition, tools, and clothing-to outposts across the Southwest, including Arizona, New Mexico, Nevada, Utah, and West Texas.

The site was chosen for its strategic location at the confluence of the Gila and Colorado Rivers, providing a transportation lifeline. Supplies were delivered by steamboats navigating up the Colorado River from the Gulf of California and stored at the Yuma depot before being distributed overland via 20-mule team freight wagons.

The depot was operational until 1883, when the Southern Pacific Railroad reached Yuma, rendering river transport obsolete. After the Army left, the facility was used by U.S. Customs, the Weather Bureau, and the Reclamation Service, continuing its legacy of public service into the 20th century.

🏛️ Preserved Historic Structures

The park features five original buildings, each meticulously restored and used today for historical interpretation:

Commanding Officer’s Quarters

An elegant adobe building with period furnishings, high ceilings, and wide verandas designed to keep interiors cool.

Reconstructed to represent the 1870s lifestyle of a senior military officer and his family.

Quartermaster’s Office

Once a busy administrative center where supplies were ordered, inventoried, and routed.

Exhibits include original documents, a telegraph station, weather station instruments, and early maps.

Demonstrates early desert water engineering techniques.

🚂 Transportation & Technology Exhibits

A restored Southern Pacific Railroad Passenger Coach is on-site, showcasing the transition from steamboat to rail transportation.

Interpretive panels explain the 20-mule team freight systems, vital in moving supplies across the arid region before the advent of trains.
