Back in prehistoric times, from about 1000 AD to 1400 AD, the Sedona/Cottonwood was home to a fair number of Ancient Ones. They were primarily farmers, but also did some hunting and gathering. Montezuma Castle was a 5-story, 20-room dwelling with a view.
Nearby is Montezuma Well, fed by a continuously flowing spring.
Along the side of the well are a couple of ancient dwellings. Notice how they built where they would be in the shade during the hot summer.
Outside of Sedona, at the end of the road where I am parked, are a couple more ruins. The Honanki cliff dwelling and rock art site was pretty impressive.
But I still think the "art" was done by ancient kids when the ancient moms sent them outside to keep them out of their hair.
I visited the nearby Palatki ruins years ago, but they are now closed because of "creaking loud noises," and may be in danger of collapsing. You can just get a distant view now. They should at least cut down the tree...
There's also some rock art (ancient kid's drawings) nearby.
Near Montezuma Well is the largest petroglyph site in the Verde Valley. It's a little hard to see in the picture because of the time of day I was there.
Here's a closeup. The whole panel is just filled with etchings.
But the most important thing about the panel is those 2 rocks that stick out at the top, and form a shadow on the panel. They make a solar calendar, by pointing to different pictures on the panel for various important dates - when to plant crops, etc.
Tuzigoot is the last site we visited, and the largest, covering the top of a long ridge. It was originally 2 stories high, with 77 ground-floor rooms.
It's impossible to get a shot of the whole thing, but this is a shot of one side from the top.
