The Colville River is a major river of the Arctic Ocean coast of Alaska in the United States, approximately 350 mi (560 km) long. One of the northernmost major rivers in the North America, it drains a remote area of tundra on the north side of the Brooks Range entirely above the Arctic Circle. The river is frozen for more than half the year and floods each spring.
It rises in an isolated area of the De Long Mountains, at the western end of the Brooks Range, north of the continental divide in the southwestern corner of the National Petroleum Reserve. It flows initially north, then generally east through the foothills on the north side of the range, broadening as it receives the inflow of many tributaries that descend from the middle Brooks Range. Along its middle course it forms the southeastern border of the National Petroleum Reserve. At the Inupiat Eskimo village of Umiat it turns north to flow across the Arctic plain, entering the western Beaufort Sea in a broad delta near Nuiqsut, approximately 120 mi (190 km) west of Prudhoe Bay. When the river freezes to a suitable thickness during winter, it can be used as an ice road to bring in supplies, as seen during the fourth season of the History Channel series Ice Road Truckers.
The river valley contains unexploited petroleum and natural gas deposits. A current proposal by the State of Alaska to bridge the river near Nuiqsut would be the first major river crossing north of the Arctic Circle in North America.
Named after Edward Colville Griffith who surveyed the region prior to the U.S. purchase.
Famous quotes containing the word river:
“Every incident connected with the breaking up of the rivers and ponds and the settling of the weather is particularly interesting to us who live in a climate of so great extremes. When the warmer days come, they who dwell near the river hear the ice crack at night with a startling whoop as loud as artillery, as if its icy fetters were rent from end to end, and within a few days see it rapidly going out. So the alligator comes out of the mud with quakings of the earth.”
—Henry David Thoreau (1817–1862)
