flows E to Kogoluktuk River, 16 mi. NE of Shungnak, Brooks Range
Prospectors' name given about 1908 and reported by P. S. Smith and H. M. Eakin, U.S. Geological Survey (USGS), in 1910 (in Brooks and others, 1911, p. 294). Lieutenant G. M. Stoney's Eskimo interpreter was called "Riley" (Stoney, 1900, p. 17). However, it was more likely named for the small steamboat John Riley which plied the Kobuk River about the time the stream was named.
