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 International Airport
Yuma's history of flight dates to 1911 when Robert Fowler took off from Yuma to set a world's record for endurance and distance. He entered a Transcontinental Air competition sponsored by William Randolph Hearst. Originating in Los Angeles, he arrived in Yuma on October 25. Over 2,000 spectators watched the aircraft circle and make a landing. The next day he succeeded in setting a world's record.
