Killik River Professional Review and Guide
"Rising amid the massive peaks of the Endicott Mountains in the central Brooks Range, the Killik River flows northward through an open, treeless, glaciated valley for 135 miles, where it joins the Colville River. The Killik's classic U-shaped river valley has deep blue lakes, sand dunes, large lateral moraines, and rolling alpine tundra.
Dramatic 6,000-to 7,000-foot peaks surrounded the headwaters. In the upper river the valley is about 2 miles wide and offers good hiking. As the river flows through the arctic foothills, the valley opens up, becoming 3 to 5 miles wide. Below Sunday Rapids, fossils are evident in rock outcroppings. The river becomes braided several miles above its confluence with the Okokmilaga River, coursing swiftly through willow islands, then across broad gravel flats that create aufeis in winter."
