Climate
editBased on the Köppen climate classification, Capital Mountain is located in a subarctic climate zone, with long, cold, snowy winters, and cool summers.[6] Weather systems coming off the Gulf of Alaska are forced upwards by the Wrangell Mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall. Winter temperatures can drop below -10 °F with wind chill factors below −20 °F.
