Figure 3: These historical aerial views of the Hiak Vatwe flowing through Torim and Bacum, two traditional Yaqui villages, show the magnitude of the river before the dam systems and extensive irrigation infrastructure were built in the 1940s. The images date from the 1920-30s; Yaquis were attacked by aerial strikes during the period 1926-29.
