History
Mount Barker was first sighted by Captain Charles Sturt in 1830, although he thought he was looking at the previously discovered Mount Lofty. Captain Collet Barker fixed this error when he surveyed the area in 1831. Sturt named the mountain in honor of Captain Barker after he was killed days later by Aborigines.
Culture
