What did Ernest Giles discover?

Answer 1

Ernest Giles made several expeditions in the Australian desert. The first, lasting four months, commenced in August 1872 and resulted in discoveries such as Palm Valley, Gosse's Bluff, Lake Amadeus, and the first sighting of Mount Olga.

Giles's next expedition departed in August 1873. On this expedition, Giles was able to approach closer to the Olgas, but his attempts to continue further west were thwarted by interminable sand, dust, biting ants, Aboriginal attack and lack of water. The loss of one of Giles's companions, Gibson, in April 1874 ended this second expedition, and the party arrived back at Charlotte Waters in July.

Giles was determined to explore the unknown country south of where Warburton and Forrest had explored, reaching Perth in the attempt. On 13 March 1875, Giles departed from Fowlers Bay, heading north first before crossing the western deserts. Although a short expedition, it was a difficult one, initially marked by severe water shortages until the discovery of permanent water holes.

Giles's fourth expedition departed from the homestead of his sponsor Thomas Elder at Beltana on 6 May 1875. On this journey, Giles was supplied with camels. From Ooldea on the northeastern edge of the Nullarbor Plain, he travelled west through the Great Victoria Desert, reaching Perth with no loss of life among his party. He then promptly turned around, re-crossing the desert back to the Overland Telegraph Line. Although he did not find good land, his main claim to fame was being the first to make the main western crossing from both directions.
