Europeans came to the Western Desert of Australia in the 1870s. They came in expeditions while the Overland Telegraph Line was being made. The first European explorer to the area was Ernest Giles. In 1872, Giles spotted Kata Tjuṯa from Kings Canyon and called it "Mount Olga", in honour of Queen Olga of Württemberg. He was not able to reach it, though, because his path was blocked by Lake Amadeus. The next year, another explorer named William Gosse reached Uluṟu and named it "Ayers Rock" after Sir Henry Ayers. More people explored the area over the next few years, to look for land they could use for raising livestock. They eventually left because the land was too dry. The native Aṉangu people had not had much contact with these explorers, and very few white people visited the area after this.
