Western Korean Mountains
In the northern Korean interior, the forested mountains around Kanggye rise above the tributaries of the Yalu. The Nangnim range includes high summits such as Hŭisaekbong, while the Changjin River cuts northeastward through the surrounding highlands to join the frontier river. Ridges and deep valleys give the region a rugged landscape, far removed from the broader lowlands of the west coast.
