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.
USS Yuma (AT-94)
Late in February 1948, she sailed to Pearl Harbor and thence proceeded to the Aleutian Islands where she operated until late August 1948. In September 1948, she steamed to Tsingtao, China, making one round-trip run between Tsingtao and Yokosuka before departing the former port, bound for Oahu on 29 November 1948. The tug entered port at Pearl Harbor on 27 December 1948 and remained there until 7 January 1949 at which time she got underway to return to the west coast. She spent February and March 1949 engaged in normal west coast operations and in April 1949 returned to the Aleutians where she served until late August 1949. The tug resumed duty along the California coast upon her arrival in San Francisco on 27 August 1949. In December, she made a round-trip voyage to Pearl Harbor and back to the west coast.
