Sag (Sagavanirktok) River: The Franklin Bluffs on the east shore of the river are a prime peregrine falcon nesting area. Iron-rich soils give the bluffs their color. The area is named for British explorer Rear Admiral Sir John Franklin, who mapped the arctic coastline and searched for the Northwest Passage. Franklin and the entire crews of his two ships, the H.M.S. Erebus and the H.M.S. Terror, perished on his last expedition in 1847 attempting to chart and navigate a section of the Northwest Passage in the Canadian Arctic when the ships became icebound. The wreck of the Erebus was finally found in September 2014 and the Terror in September 2016.

Atigun Pass

Atigun Pass, in the Brooks Range, is where the Dalton Highway crosses the Continental Divide, at mile marker 244. It is the highest pass, at 4739', in Alaska that is maintained year-round and the only pass in the Brooks Range that is crossed by a road. It is a difficult pass to negotiate in a small plane due to its rapid elevation and heading change (hence the markers); Anaktuvuk Pass is a safer flight route.
