The Pitkäyön Vuoret (La. "Mountains of Long Night") were a great tumble of mountains to the north of the Minheldolath which got their name from the Jäämiehet who hunted there, who said that "a man had to keep a vigil throughout the night against the many creatures that prowl the darkness". Many smaller stretches of this long string of peaks had local names. Therefore, travelers in the region were well advised to learn these many names and be certain of exactly which section of the Ered Rhívamar was being discussed by the local natives before exploring there.
