Baekdu Mountain, also known in China as Changbai Mountain and Baitou Mountain, is an active volcanic mountain on the border between North Korea and China. It is visible here by way of its snow-capped peak, near the image center.
At 2,744 m (9,003 ft), it is the highest mountain of the Changbai mountain range to the north and Baekdudaegan mountain range to the south. It is also the highest mountain in the Korean Peninsula and in northeastern China. A large crater lake, called Heaven Lake, is in the caldera atop the mountain.
