In 1836, the explorer and Surveyor General of New South Wales Sir Thomas Mitchell renamed Gariwerd after the Grampian Mountains in his native Scotland. According to Wilkie, Mitchell first referred to Gariwerd as the Coast Mountains, and in July 1836 called them the Gulielmian Mountains after William IV of the United Kingdom (Gulielmi IV Regis)). Members of his expedition referred to the mountains as the Gulielmean, Gulielman, and the Blue Gulielmean Mountains. Later in 1836, Mitchell settled on the Grampians, and the Grampians National Park would also take this name in 1984.
