The Bone Mountains (often referred to simply as the Bones) are the largest mountain range in the known world, running from the northern (Shivering Sea) to the southern (Jade Sea) coast of Essos and completely bisecting the continent. The Bones are located to the east of Vaes Dothrak, the Red Waste, and Qarth, and are one of the major barriers to east-west land travel across Essos.
