The rock is made od arkose, a type of red sandstone that contains large quantities of deldspar. Various oxides of iron are also present. This composition accounts for the remarkable changes in colour that occur as night sives way to dawn, dawnto daylight and daylight to dusk. Many people visit Uluru simply to watch the effects of light at different times of day and during different seasons.When it rains the rock appears to have a liquid silver skin. Surface grooves become raging torrents, and the water that cascades down the reck's precipitous sides forms transient pools on the surrounding desert floor.
Every fissure of Uluru has powerful connotations for the Aborigines. Regardless of the numbers of people who visit the rock, Aborigines consider themselves custodians of a symbolic landscape bequeathed to them by their ancestors;Uluru is central to that landscape.
