The two flat topped hills south of the road are composed of the Wrangell Lavas partially mantled by rock debris and soils that contain permafrost. During summer thaws of this frozen terrain, surface materials are slowly transported downslope by creep and semi-fluid flow. The hummocky area at the base of the western hill was produced by an ancient landslide. Mile 35.3. Jack Creek Rest Area. Several nice campsites with picnic tables and fishing along Jack Creek. There is a vault toilet at this rest area. Look for Dall sheep in this area. These bright white, wild sheep inhabit high altitude ridges, meadows, and extremely rugged terrain. Sheep use these areas for feeding, resting, and to escape predators. Although they usually stay at higher elevations, in this area they are known to descend to springs and mineral licks. Careful observers can usually spot small flocks on the mountainsides over the next few miles.
