Summary Author: David Wigglesworth
Uluru (Ayers Rock), one of the world’s most recognizable natural landmarks, is a huge arkose sandstone formation located in central Australia. Its total circumference is 5.8 mi (9.4 km) and it stands 1,142 ft (348 m) high. Actually, most of the mass of Uluru lies underground, perhaps as far as 3.5 mi (6 km). About 70 percent of the Australian continent is considered arid. The long-term average annual rainfall at Uluru in the southern part of the Northern Territory is about 12 in (300 mm) yet seasonal and annual rainfalls are extremely variable. Although rain may fall at any time of the year in the vicinity of Uluru, heavy rains are more likely between November and March. My wife visited Uluru in mid-September 2010, the wettest September on record. Heavy rains led to the waterfalls shown above. Rainfall to the point of causing cascades down the sides of Uluru rarely occurs here. Uluru-Kata Tjuta National Park is an UNESCO World Heritage site. Photo taken on September 14, 2010.
