YUMA PROVING GROUND - ARMY HISTORY
The presence of the U.S. Army in Yuma goes back to 1850, when Fort Yuma was constructed on a hill overlooking the important Yuma crossing of the Colorado River. Soldiers at Fort Yuma maintained peace with the local Indians and protected the important Yuma crossing, which was used by thousands of travelers each year. The fort operated until 1883.
