The Bluestone River is unlike other river crossings along the Teller Road because it flows northward to Imuruk Basin rather than south to Norton Sound. The river is deeply incised as it cuts through steep mountains, creating steep, rocky slopes and cliffs. Rough-legged hawk, golden eagle, gyrfalcon, and common raven may nest on nearby rock cliffs
This high point in the road gives you an excellent view across the valley. Three ditch lines from earlier mining activities are apparent on the far side of the valley, especially where they cross the exposed rock face of Cape Horn. The ditches originate near Hudson Creek about 12 miles upstream. Today these deep, wide gashes on the hillside offer cover and easier movement for wildlife—especially moose and grizzly bears.
The rocky outcrop across the Solomon River usually hosts an active golden eagle nest. Look for a huge tower of sticks and splashes of whitewash and orange lichen in the vicinity of the nest and surrounding perching sites. Built by eagles and added onto in successive years, the nest i s distinctive for its large size, construction, and shape. When not occupied by eagles, the large nest may be used by gyrfalcons.
River crossing warning! Unlike other braided rivers along the road system, the Niukluk River flows along a single broad channel. A large colony of cliff swallow inhabits the cliff banks downstream while tree swallow nest in aspen cavities and nest boxes put up by Council residents. Osprey, which nest down- stream, may be spotted flying over the river. Bald eagle are also associated with the river and nest at the Fish River confluence
