Fort Buchanan was a United States Army post founded in 1856 three miles southwest of present day Sonoita Arizona in what is now called Hog Canyon. The fort was located on the east slope of the canyon and under constant threat by Apaches. The dramatic increase in fighting with the Apache was initiated by the Lt Bascom Affair that was started near Sonoita. Lt Bascom and his patrol were based at Ft Buchanan.
