What Is Australia's Ayers Rock?

In Central Australia is a unique wonder—the largest single stone in the world. It is all alone, rising abruptly on a plain. Called Ayers Rock, it towers more than 1,100 feet above the surrounding plain and is about two miles long. Imagine a vast solid sandstone dome covering an area of 1,200 acres and measuring more than five miles around its base!
An idea of the immense size of this monolith can be gained by putting up against the rock face the famed Sydney Harbour Bridge (from the waterline to the top of the arch), adding to this a ten- to twelve-story building, and the two together would not reach to the top of the cliff face. Or, envision a single stone just 107 feet short of the Empire State Building's original height or 159 feet higher than the Eiffel Tower.
During the daytime, the rock's coarse sandstone provides striking, ever-changing colours. And during sunrise and sunset, it glows from a deep purple to a brilliant orange.
