OLGAS

also called Olga Rocks, tors (isolated weathered rocks) in southwestern Northern Territory, Australia, comprising a circular grouping of more than 30 red conglomerate domes rising from the desert plains north of the Musgrave Ranges. They occupy an area of 11 sq mi (28 sq km) within Uluru National Park (established in 1958 as the former Ayers Rock-Mount Olga National Park), and culminate at Mt. Olga, 1,500 ft (460 m) above the plain and 3,507 ft above sea level. Mt. Olga is the most westerly of Australia's three giant tors; the others are Ayers Rock (called Uluru by the region's Aborigines) and Mt. Conner. They were visited and named in 1872 after Queen Olga of Wrttemberg by the explorer Ernest Giles. Their Aboriginal name, Katajuta means many heads. The rocks offer visitors a constantly changing array of colour as the sun moves overhead and illuminates the luxurious vegetation in deep clefts between the domes.
