They had carved hundreds of miles of canals in the Sonoran Desert with stone tools and channeled the waters of the Salt and Gila Rivers to irrigate their crops for a thousand years until, in the middle of the 15th century, because of social conflict or climate change—drought, floods—their technology became obsolete, their civilization collapsed, and the Hohokam scattered.
Four hundred years later, when white settlers reached the territory of southern Arizona, they found the ruins of abandoned canals, cleared them out with shovels, and built crude weirs of trees and rocks across the Salt River to push water back into the desert.
Aware of a lost civilization in the Valley, they named the new settlement Phoenix. Check out more from this issue and find your next story to read. It grew around water.

There are now 5 million. The Valley is one of the fastest-growing regions in America, where a developer decided to put a city of the future on a piece of virgin desert miles from anything. At night, from the air, the Phoenix metroplex looks like a glittering alien craft that has landed where the Earth is flat and wide enough to host it. Phoenix makes you keenly aware of human artifice—its ingenuity and its fragility. The American lust for new things and new ideas, good and bad ones, is most palpable here in the West, but the dynamo that generates all the microchip factories and battery plants and downtown high-rises and master-planned suburbs runs so high that it suggests its own oblivion.
Growth keeps coming at a furious pace, despite decades of drought, and despite political extremism that makes every election a crisis threatening violence. Democracy is also a fragile artifice. It depends less on tradition and law than on the shifting contents of individual skulls—belief, virtue, restraint. Its durability under natural and human stress is being put to an intense test in the Valley. And because a vision of vanishing now haunts the whole country, Phoenix is a guide to our future.
