Columbia River
The Columbia River is a large river in the Pacific Northwest region of North America. Its headwaters are in British Columbia. Its lower reaches form the border between Washington state and the state of Oregon.[1] Tributaries drain parts of Montana, Nevada, Wyoming, Utah and Idaho.
Navigation
[edit | edit source]The river carries a lot of suspended silt. As the river water slows, around the river's mouth, it forms a large and dangerous sandbar, which is a navigational hazard, particularly when waves are large.[2]
Portland, Oregon, which lies approximately 75 miles (121 km), from the river's mouth, was an important port in the 19th century, until Seattle was added to the North American railway grid.
