There isn't a single elevation number for all of Arizona because the state is very mountainous and has a wide range of elevations.

* Highest point: Humphreys Peak at 12,633 feet (3,851 meters) above sea level.

* Lowest point: The Colorado River at 70 feet (21 meters) above sea level.

So, while there's no single number, Arizona has a significant amount of elevation change across its landscape.
