The area provides the opportunity to experience extreme winter sports unmatched anywhere in the Sierra Nevada. Permits are required to use the area but are free of charge - contact the Bridgeport Ranger Station, (760) 932-5899, for info on permits and maps. You can request a permit up to 24 hours in advance Monday - Friday between 8am and 2pm. For more information visit the Humboldt-Toiyabe Forest Service.
