Located in Australia, a giant (348 meters (380 yards) high, 9.4 kilometers (5.8 miles) wide), red rock formation (arkosic sandstone) in the middle of the desert (500 kilometers (300 miles) west of Alice Springs).

Named by a European explorer (Ernest Giles) who "discovered" it in 1872. He named it for the South Australian premier of the time, Sir Henry Ayers.

(which begs the question be asked, would he have so named it had he known that it already had a name? and if he had had E2 available to him, could he have found it? but I digress...)
