[2] The linguist Margaret Sharpe was deterred from pursuing more intensive studies of Mangarayi by a station owner who grew annoyed with the presence of metropolitan anthropologists and linguists coming to study the indigenous people on his cattle run.
[3] The Mangarayi held sway over an estimated 4,500 square miles (12,000 km2) of land on the middle and upper courses of Roper River as far as Mount Lindsay.
Their traditional grounds took in east of Mataranka and Maranboy, Mount Emily, Elsey, and Beswick.
