When the Spanish conquistadors first came to northern Arizona, they proclaimed it the “sierra sin agua,” mountains without water, because of the peculiar absence of rivers and streams. But this harsh, beautiful land below the snow-capped San Francisco Peaks has long nourished humans, including the ancestors of today’s Hopis, the Hisat’sinom. Showcasing new research from Wupatki, Sunset Crater, and Walnut Canyon, this book tells the story of the diverse, mobile, and adaptive peoples who inhabited this region and borrowed from their Ancestral Pueblo and Hohokam neighbours while maintaining distinctive styles of their own.
