Kobuk Valley in December: what the park service says

December gives Kobuk Valley its shortest days: on December 21 the sun is above the horizon for only about an hour and a half, though the twilight lasts for hours. The long dark makes winter the best season for northern lights during high solar activity. Mount Angayukaqsraq, the park's highest point, rises to 4,760 feet, and like every winter visit, a December trip needs advanced cold-weather survival knowledge.
