From the parched dry plains of the Northern Territory, rises the biggest monolith in the world, the colossal Uluru (previously known as Ayers Rock). Called Ayers Rock by settlers, the ownership of the rock was transferred to the Aboriginals of the area and it regained its Aboriginal name of Uluru, which means Great Pebble. Uluru is one of Earth's great natural wonders. Consisting of mineral rich sandstone, Uluru measures 2.4km (1.5 miles) long and 1.6km (1 mile) wide and rises up to 867 metres above sea level. Uluru is also considered a spiritual place.
