Iron Mountain (Silver Basin/Ski Sundown/Iron Mountain/Carson Ski Area)

Iron Mountain is a former ski area in California, now abandoned. It operated under several names—Silver Basin, Ski Sundown, and Carson Ski Area among them—but no longer functions as a commercial resort. The site sits in the backcountry of CA's high country and is largely inaccessible to visitors seeking a ski experience. What remains is a historical artifact of mid-20th-century ski development rather than a viable destination. Access is difficult, facilities are gone, and there is no reason to visit expecting operational lifts or groomed runs.
