Before the river joins the sea, at about upstream it forms two branches; the western branch is called the York River and the eastern branch is called the McKillop River. The York River rises on the eastern flanks of Brooks Mountain,〔 the highest point in the York Mountains, in the central part of the Teller Quadrangle. It flows in a northeast direction and then confluences with the McKillop River. The river flows through a valley formation of width. The geological formation reported in the valley consists of slate and is exposed in some stretches of the river. The river bed is strewn with gravel and pebbles of slate and limestone. The gravel and pebbles have their origin in the Kuzitrin series. The limestones are derivatives of the Port Clarence limestones.〔 The McKillop branch has its source in the limestone hills, which are an eastern arm of the York Mountains. The geological formation in this river valley is made up only of limestones and belongs to the Port Clarence formation.〔
