Kolumbijská pánev (anglicky Columbia Basin) je pánev, sníženina obklopená horskými hřbety na jihovýchodě státu Washington (okrajově přesahuje do Oregonu a Idaha), ve Spojených státech amerických. Rozkládá se, respektive je součástí Kolumbijské plošiny.[1] Je vyplněná čedičovými lávami z miocénu a částečně i sedimenty.[2]

Drumheller Channels National Natural Landmark.jpg
w:Drumheller Channels National Natural Landmark showcases the Drumheller Channels, which are the most significant example in the w:Columbia Plateau of basalt butte-and-basin w:channeled scablands. This w:National Natural Landmark is an extensively eroded landscape, located in south central w:Washington state characterized by hundreds of isolated, steep-sided hills (buttes) surrounded by a braided network of numerous channels, all but one of which are currently dry. It is a classic example of the tremendous erosive powers of extremely large floods such as those that reformed the Columbia Plateau volcanic terrain during the late w:Pleistocene glacial w:Missoula Floods.
