When early #wilderness advocate Bob Marshall got to this point, at the headwaters of the North Fork of the Koyukuk River, he bestowed the name Gates of the Arctic upon the two #mountains flanking the river, Boreal Mountain and Frigid Crags. According to him, "No sight or sound or smell or feeling even remotely hinted of men or their creations. It seemed as if time had dropped away a million years and we were back in a primordial world."
