The Columbia River forms a wide, complex boundary between Oregon and Washington in this 2017 survey, defining the industrial and natural character of the region. The river is a corridor of active commerce, featuring the BNSF Railway and the Bybee Ledge Channel which facilitate transport through the valley. Along the banks, settlements like Columbia City and Woodland are connected by a network of roads including Old 99, while landforms like Deer Island and Martin Island divide the primary flow from numerous sloughs and side channels.
