A canyon carved over millions of years
The Grand Canyon is about 446 km (277 miles) long and up to 1,857 m (6,093 ft) deep, carved by the Colorado River.

Arizona is the fourteenth-most populous state and one of the fastest-growing in the country. Almost two thirds of its residents live in Maricopa County, around Phoenix — the fifth-largest city in the United States. Semiconductors, aerospace, tourism, healthcare and retirement migration drive the economy, while the Colorado River and Central Arizona Project make water the state's defining long-term constraint.
