Question: why did they change ayers rock to uluru

title: Uluru
text: While exploring the area in 1872 , Giles sighted Kata Tjuta from a location near Kings Canyon and called it Mount Olga , while the following year Gosse observed Uluru and named it Ayers Rock , in honour of the Chief Secretary of South Australia , Sir Henry Ayers . Further explorations followed with the aim of establishing the possibilities of the area for pastoralism . In the late 19th century , pastoralists attempted to establish themselves in areas adjoining the Southwestern / Petermann Reserve and interaction between Aṉangu and white people became more frequent and more violent . Due to the effects of grazing and drought , bush food stores became depleted . Competition for these resources created conflict between the two groups , resulting in more frequent police patrols . Later , during the depression in the 1930s , Aṉangu became involved in dingo scalping with ' doggers ' who introduced Aṉangu to European foods and ways .
