Title: Columbia River
Content:  The Columbia begins its 1243 mi journey in the southern Rocky Mountain Trench in British Columbia (BC). Columbia Lake – 2690 ft above sea level – and the adjoining Columbia Wetlands form the river's headwaters. The trench is a broad, deep, and long glacial valley between the Canadian Rockies and the Columbia Mountains in BC. For its first 200 mi, the Columbia flows northwest along the trench through Windermere Lake and the town of Invermere, a region known in British Columbia as the Columbia Valley, then northwest to Golden and into Kinbasket Lake. Rounding the northern end of the Selkirk Mountains, the river turns sharply south through a region known as the Big 
Title: Columbia, South Carolina
Content:  One of Columbia's more prominent geographical features is the fall line, the boundary between the upland Piedmont region and the Atlantic Coastal Plain, across which rivers drop as falls or rapids. Columbia developed at the fall line of the Congaree River, which is formed by the confluence of the Broad and Saluda rivers. The Congaree was the farthest inland point of river navigation. The energy of falling water also powered Columbia's early mills. The city has capitalized on this location, which includes three rivers, by identifying as "The Columbia Riverbanks Region". Columbia is located roughly halfway between the Atlantic Ocean and the Blue Ridge Mountains, at an elevation around 292

U.S. Route 165 passes through the center of town and bridges the river, leading north 32 mi to Monroe and south 64 mi to Alexandria. According to the United States Census Bureau, the town has a total area of 2.00 km2, of which 1.96 km2 is land and 0.03 sqkm, or 1.75%, is water.
Title: Steamboats of the upper Columbia and Kootenay Rivers
Content:  The Columbia River begins at Columbia Lake, flows north in the trench through the Columbia Valley to Windermere Lake to Golden, British Columbia. The Kootenay River flows south from the Rocky Mountains, then west into the Rocky Mountain Trench, coming within just over a mile (1.6 km) from Columbia Lake, at a point called Canal Flats, where a shipping canal was built in 1889. The Kootenay then flows south down the Rocky Mountain Trench, crosses the international border and then turns north back into Canada and into Kootenay Lake near the town of Creston. The upper Columbia and the upper 
Title: Columbia, Tennessee
Content:  Columbia is located at 35.615°N, -87.04444°W (35.615022, −87.044464). It developed along the banks of the Duck River at the southern edge of the Nashville Basin; the higher elevated ridges of the Highland Rim are located to the south and west of the city. The Duck River is the longest river located entirely within the state of Tennessee. Free flowing for most of its length, the Duck River is home to over 50 species of freshwater mussels and 151 species of fish, making it the most biologically diverse river in North America. It enters the city of Manchester and meets its confluence with a major tributary, The Little Duck River, at Old Stone Fort State Park. The fort was named after an ancient Native American structure, between the two rivers, believed to be nearly 2,000 years old. The Duck River is sacred to most of the founding Native American tribes east of the Mississippi River. According to the United States Census Bureau, the city has a total area of 29.6 sqmi, of which 29.6 sqmi is land and 0.03% is water. Incorporated in 1817, the city is at an elevation of 637 ft.
Title: Columbia, Missouri
Content:  the rigorous Southeastern Conference. The city rests upon the forested hills and rolling prairies of Mid-Missouri, near the Missouri River valley, where the Ozark Mountains begin to transform into plains and savanna. Limestone forms bluffs and glades while rain dissolves the bedrock, creating caves and springs which water the Hinkson, Roche Perche, and Bonne Femme creeks. Surrounding the city, Rock Bridge Memorial State Park, Mark Twain National Forest, and Big Muddy National Fish and Wildlife Refuge form a greenbelt preserving sensitive and rare environments. The Columbia Agriculture Park is home to the Columbia Farmers Market. The first humans who entered the area at least 12,000 years ago were nomadic hunters. Later, woodland tribes lived in villages along waterways and built 
Title: Columbia, Illinois
Content:  Columbia is located at 38.44917°N, -90.20861°W (38.449172, -90.208500). According to the 2010 census, Columbia has a total area of 10.476 sqmi, of which 10.41 sqmi (or 99.37%) is land and 0.066 sqmi (or 0.63%) is water. Columbia is bounded on the west by the Mississippi River. Running in a diagonal line just northeast of Columbia is the border of St. Clair County, beyond which lies Dupo to the north and Millstadt to the east. To the south is Waterloo. Waterloo and Columbia are expected to grow right up to the borders of the other, in effect extending St. Louis's urban sprawl from South St. Louis County across the Jefferson Barracks Bridge into the heart of the formerly rural Monroe County.
Title: Columbia River drainage basin
Content:  in North or South America. In its 1270 mi course to the Pacific Ocean, the Columbia flows through four mountain ranges—the Rockies, Selkirks, Cascades, and coastal mountains—and drains 258000 mi2. The mainstem of the Columbia rises in Columbia Lake on the west slope of the Rocky Mountain Range in Canada. Its largest tributary, the Snake, travels 1038 mi from its source in Yellowstone National Park in Wyoming before joining the Columbia. When Lewis and Clark explored the region in the early 19th century, huge numbers of fish (salmon) returned to spawn every year. "The multitudes of this fish are almost inconceivable," Clark wrote in the autumn of 1805. At that time, the Columbia and its tributaries provided 12935 mi of pristine river habitat.
