On October 12, 1940, while driving his 1937 Cord Sportsman through the Arizona desert he took a turn too fast, a suitcase broke loose and struck him in the head and his car plunged into a ravine. The ravine was later named "The Tom Mix Wash" in his honor. A plaque at the location reads: "TOM MIX January 6, 1880 - October 12, 1940 Whose spirit left his body on this spot and whose characterization and portrayals in life served to better fix memories of the old west in the minds of living men.".
