The Misty Mountains cold
Tolkien’s original illustration of the Misty Mountains
From Tolkien Gateway:
The Misty Mountains or Mountains of Mist (Hithaeglir in Sindarin as a plural) was a great mountain range that lay between Eriador in the west and the Great River Anduin in the east. They ran 795 miles (1,280 kilometers) from Mount Gundabad in the far north to Methedras in the south. Some of the peaks may have been as high as 12,000 feet (3,660 meters).
They were, in fact, cold; also misty.
