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 metres (2,444 ft), about 40 kilometres (25 mi) northwest of Old Crow. The river travels 15 kilometres (9 mi) west to reach the United States border, where it crosses into Yukon–Koyukuk Census Area, Alaska at 67°38′30″N141°00′00″W / 67.64167°N 141.00000°W / 67.64167; -141.00000 at an elevation of 476 metres (1,562 ft). The river reaches its mouth at the Porcupine River at an elevation of 197 metres (646 ft), 12.8 kilometres (8.0 mi) north of the settlement of Old Rampart.

Prindle Volcano is an isolated basaltic cinder cone located in eastern Alaska, United States, in the headwaters of the East Fork of the Fortymile River. The cone is fresh-looking and has a base approximately 900 metres wide. It is the northwesternmost expression of the Northern Cordilleran Volcanic Province. The cinder cone, and an approximately 11-kilometre (6.8-mile) long lava flow which breached the margin of the cone, erupted in the Pleistocene approximately 176,000 years ago. Rocks forming the Prindle Volcano occur within, and penetrated through, the Yukon–Tanana upland which is a large region of mostly Paleozoic-Mesozoic metamorphosed and deformed sedimentary, volcanic, and intrusive rocks that are intruded by younger Cretaceous and Cenozoic granitic rocks. Xenoliths in the volcano's ejecta provide a sample of lower crust material.
