Historical Significance: A marker was placed near the Old Butterfield Overland Mail Trail to commemorate the passenger and mail service that ran overland from St. Louis to San Francisco from 1859 to 1861. The Civil War interrupted the stagecoach mail service, and railroads later replaced them. The Arizona stage line followed roughly the current Interstate 10 and ran through the Dragoon mountains to take advantage of natural springs in the area that had been used for hundreds of years by the Apaches. The marker was later moved to Wellton, Arizona, which is 29 miles east of Yuma and had served as a water stop (well town) for the Butterfield Stage and the railroad.
