Yuma Crossing
Immediately after the Mexican–American War in 1848, the U.S. Army built Fort Yuma here to protect travelers from Indians raiding the area. It was the center point of conflict in the Yuma War of 1850–53. From 1864–1890, the fort and nearby facilities was the main army base to support the US Army's efforts to control the Indians throughout the greater southwest.
Yuma (YTM-748)
The third USS "Yuma" (YTM-748) was a medium harbor tug that served in the United States Navy from 1964 to 1976.
"Yuma" was built at San Diego, California, by National Steel and Shipbuilding Company (NASSCO), for the United States Army, which took delivery of her in 1954, and designated her "large tug" "LT-2078". The U.S. Navy acquired "LT-2078" from the Army in September 1964. The Navy classified her as a medium harbor tug, designated her YTM-748, and named her "Yuma".
