The Olgas are located just 25km west of Uluru/Ayer’s Rock. They are a series of 36 domes that hold greater importance for Aboriginal peoples than Uluru. The domes are composed of conglomerate rock-pebbles cemented together with a sandstone matrix. Each dome looks like a head and this feature gives rise to the Aboriginal name ‘The Olgas’, meaning ‘many heads’. The customs, practices and stories associated with Uluru are largely known but great mystery still surrounds the significance of The Olgas. Tourism in the ‘red centre’ began in the 1940s but the environmental and cultural impact of up to 500,000 tourists visiting each year has been curbed through strict management.
This picture shows two of the domes which create a valley known as the Valley of the winds. The composition of the conglomerate rock can be clearly seen in the foreground boulders.
