Image of Gila River at Calva (09466500), March 6, 1932.
W.E. Dickinson, #1053 The Gila River was ravaged by floods in the 1910s and 1920s, including one flood estimated at 100,000 ft3/s in 1916. This upstream view from the railroad bridge at Calva shows a wide, braided channel. An open cottonwood gallery forest appears in the midground at left (channel right), and the low shrubs at right appear to be native willows.
