Point of correction, it's the Hohokam and not the Mogollons that are known for their massive canal systems. The people inhabiting the broader Mogollon region had fairly small irrigation networks that don't really justify the term "canal". Most archaeologists would also have some quibbles with describing Hohokam irrigation as truly decentralized, particularly in e.g. the civano phase, but it's accurate enough I guess.
