Uluru / Ayers Rock....From Space.

Uluru also known as Ayers Rock, is a large sandstone rock formation in the southern part of the Northern Territory, central Australia.

Uluru is one of Australia's most recognisable natural landmarks. The sandstone formation stands 1,142 ft high, with most of its bulk lying underground, and has a total circumference of 5.8 miles. Uluru is notable for appearing to change colour at different times of the day and year, most notably glowing red at dawn and sunset.

Uluru is an inselberg, literally "island mountain", an isolated remnant left after the slow erosion of an original mountain range

Uluru is dominantly composed of coarse-grained arkose and some conglomerate. Average composition is 50% feldspar, 25–35% quartz and up to 25% rock fragments; most feldspar is K-feldspar with only minor plagioclase as subrounded grains and highly altered inclusions within K-feldspar. The grains are typically 2–4 millimetres in diameter, and are angular to subangular; the finer sandstone is well sorted, with sorting decreasing with increasing grain size. The rock fragments include subrounded basalt, invariably replaced to various degrees by chlorite and epidote.
