History
With a billion years of geological history laid open like pages in a book, the Grand Canyon has countless stories to tell. Even the last 1,000 years of human occupation is but a side note. Besides the spectacular canyon sculpted by erosion, weather, and tectonic forces, you can witness the effects of volcanic action at Sunset Crater Volcano National Monument.
In terms of human history, some of the earliest remaining traces the Ancient Puebloan structures at Wupatki and Walnut Canyon national monuments. The timeline continues through the Old West and the founding of Flagstaff with Heritage Square, the Arizona Pioneer Museum, and Riordan Mansion State Park, into modern times at the Museum of Northern Arizona.
