You see this?

That's not a river. That's the South Canal in Mesa, Arizona (Phoenix metro area).

This is a view of the East and South canals. At least half of all the Phoenix metro canals were originally built by the Hohokam (from roughly 200-1400 CE), and are still in use (restored) today.

Phoenix, Arizona actually has more miles (kilometers) of Canals total than both Venice and Amsterdam. No, really. Phoenix has about 180 miles of canals, many of which are built on ancient canal foundations.

below is an aerial view photo taken in the late 1930's of one branch of Phoenix's canal systems:

Also have the "Montezuma Castle," if you need a castle:

1. borrowing misery from future

2. carrying grief of the past
