Uluru (Ayers Rock) is one of Australia's most recognisable natural icons.
The world-renowned sandstone formation stands 348 m high above sea level with most of its bulk below the ground, and measures 9.4 km in circumference.
Uluru appears to change color as the different light strikes it at different times of the day and year.
