The White Knife river flows south out of Long Lake to the west: a tributary of the White Knife originates in the Lonely Hills, merging with the main river further south.
The Lonely Hills appear on a map that the Boltons look over.
In the books
In the A Song of Ice and Fire novels, the Lonely Hills are within the lands of House Umber.
