Mount Jefferson is the second highest mountain in Oregon. Though it is smaller than Mount Hood, it is more rugged and more remote. It is the oldest volcano in the region, and consequently is more heavily eroded. Its normal route is the steepest, most difficult climb of Oregon's high summits, culminating in a steep snow climb to the summit, which is itself a towering 400 foot rock pinnacle. The mountain is located within the Mount Jefferson Wilderness Area.
