Historical Image of the Day

This week's series covers issues of water in the American West, a topic dear to me.

Hohokam irrigation canal, Arizona. Not sure when the canal was constructed, but Indians in the region were building irrigation canals from around 300 until a massive flood in 1358 destroyed much of the system and helped lead to the decline of Hohokam culture. Excavation and photo is from the 1960s.
