"Tuzigoot National Monument, Arizona Water flows under and through this landscape, feeding the growth of people and towns. The Verde Valley is watered by snowmelt, summer monsoons, and springs that well up from the ancient sedimentary rocks. In the heart of the valley, a thousand years ago, people began to build a little hilltop pueblo that would grow into one of the largest villages in the area." nps.gov/tuzi/index.htm
