Austa Ridge (Bulgarian: italic=yes|хребет Ауста, ‘Hrebet Austa’ \'hre-bet a-'us-ta\) is the partly ice-free ridge extending 24 km and 11 km wide on Oscar II Coast in Graham Land descending eastwards from the south extremity of Forbidden Plateau towards Caution Point. It rises to over 1800 m[1] at its west extremity, and surmounts Jorum Glacier and Borima Bay to the north, Exasperation Inlet to the east, and Spillane Fjord and Crane Glacier to the south. The feature is named after the settlement of Austa in Southern Bulgaria.
