Chambers Pillar

Chambers Pillar (Aboriginal name Idracowra or Etikaura) is a sandstone formation some 160 km (100 mi) south of Alice Springs in the Northern Territory of Australia.

Erosion by wind and rain has left an isolated pillar of 350-million-year-old sandstone, rising 50 m (160 ft) above the surrounding plain. The rock formation and the surrounding area of 340 hectares, or 3.4 km2 (1.3 sq mi), are officially named the Chambers Pillar Historical Reserve.
