Looking at Montezuma Castle, I was reminded of Howard Zinn's book A People's History of American Empire where Zinn threads truth throughout historical events, thereby toppling pre-fabricated stories--from our long tradition of spin--better known in schools today as History 101.
Montezuma Castle was home to the Southern Sinagua (meaning without water) natives, just outside of Sedona.
It's a popular stop in the Verde Valley along the way from Phoenix to Sedona and Flagstaff, Arizona. As are its sister sites, Montezuma Well and Tuzigoot.
Montezuma was the Aztec king in what is now Mexico and Central America.
When the Europeans "discovered" America, they thought the remnants of these cliff dwellers was the work of Aztecs, hence the name Montezuma.
