However, here's some information about the general area:
* Page, Arizona is located at an elevation of 3,770 feet (1,149 meters).
* The Navajo Nation reservation where Antelope Canyon is located generally sits at an elevation between 3,000 and 5,000 feet (914 and 1,524 meters).
Therefore, you can estimate that the elevation of Antelope Canyon is likely within that range, between 3,000 and 5,000 feet.
For a more precise elevation, you would need to specify a specific point within the canyon.
