History
Prospectors' name given about 1886; so called because the mouth of the stream is about 40 miles below the former Hudsons Bay post called "Fort Reliance." It was called "Cone-Hill River" by Lieutenant Schwatka (1885, p. 248), USA, "from the fact that three is a prominent conical hill in the center of its broad valley, near its mouth." Gold was discovered here late in 1886 (Spurr, 1898, p. 115).
