“Casa Grande” is the Hohokam Native American ruins located near Coolidge, Arizona. The Hohokams had an interesting civilization. They farmed and irrigated crops using complex engineering skills. The four walls of this house are aligned with the four points of the compass. There is a feature where holes in the walls projected light onto a particular place on the wall to indicate equinoxes and solstices. Sort of like Stonehenge, I suppose. After our visit we headed to the Arizona High country. More on that tomorrow.
