Arizona City or Arizona is the name of the original settlement at the Yuma Crossing, in what is now Yuma, Arizona. From 1853 a small settlement, Arizona City, grew up on the high ground across from Fort Yuma, first as the adobe residence of Mrs. Bowman the fort's mess cook. This was purchased for use as a store the next year by George F. Hooper. On the mail route with the arrival of the San Antonio-San Diego Mail Line in 1857, and the Butterfield Overland Mail in 1858, the town received its post office of Arizona with its first postmaster John Blake Dow March 17, 1858. At that time it consisted of adobe dwellings, two stores and two saloons.
