From A Wiki of Ice and Fire
The Dry Bones is a name sometimes applied to the southern Bone Mountains, in central Essos. Located east of the red waste and west of the Great Sand Sea, they are so-named because water is sparse there. They do not seem to have the snowcapped mountains of the northern Bones, which are called the White Mountains (Krazaaj Zasqa) due to their snow cover. The Dry Bones are scoured by sandstorms (apparently from the red waste), which carve the mountains into strange shapes.
Bayasabhad is located in the middle of the Dry Bones. Despite the mountains' inhospitable nature, the Sand Road runs through them via Bayasabhad, connecting overland caravan routes between Yi Ti to the east and Qarth to the west.
