Rapid River (Alaska-Yukon)

The Rapid River is a river in Yukon, Canada and Alaska, United States.

Etymology
The stream was published as Sucker River by the U.S. Coast and Geodetic Survey (USC&GS) in 1890. The current name was mentioned by R. G. McConnell of the Geological Survey of Canada in 1888. It was so named because of the "boulder stream rapids that extend three quarters of a mile up stream from its mouth."

Hydrology
The source of the Rapid River is on the slopes of Lahchah Mountain at an elevation of 745 m, about 40 km northwest of Old Crow. The river travels 15 km west to reach the United States border, where it crosses into Yukon–Koyukuk Census Area, Alaska at 67.64167°N, -141°W at an elevation of 476 m. The river reaches its mouth at the Porcupine River at an elevation of 197 m, 12.8 km north of the settlement of Old Rampart.
