The Columbia River is one of the most iconic and ecologically significant rivers in the United States, stretching over 1,243 miles from its source in British Columbia, Canada, to its mouth in the Pacific Ocean. A comprehensive map of the Columbia River is essential for understanding its geography, hydrology, and the various human activities that depend on it. In this article, we will delve into the details of the Columbia River map, exploring its course, notable features, and the importance of this waterway to the environment, economy, and indigenous communities.
Geography and Course of the Columbia River
The Columbia River originates in the Rocky Mountains of British Columbia, Canada, and flows southwest through the Canadian province before crossing into the United States. It then forms the border between Washington and Oregon, eventually emptying into the Pacific Ocean. The river’s course is marked by a variety of landscapes, including mountainous regions, fertile valleys, and rugged coastlines. Along its journey, the Columbia River is joined by numerous tributaries, the most significant of which include the Snake River, the Willamette River, and the Pend Oreille River.
Notable Features and Landmarks
A map of the Columbia River highlights several notable features and landmarks. The river is home to numerous dams, which provide hydroelectric power, irrigation, and flood control. The largest and most well-known of these dams are the Grand Coulee Dam, the John Day Dam, and the Bonneville Dam. Additionally, the Columbia River Gorge, a scenic and geologically unique area, stretches over 80 miles and offers stunning views, hiking trails, and water sports. The river also flows through or near several major cities, including Portland, Oregon, and Vancouver, Washington, supporting a diverse range of economic activities such as shipping, fishing, and tourism.
| Section of the River | Length (Miles) | Notable Features |
|---|---|---|
| Upper Columbia River | 470 | Origin in British Columbia, mountainous terrain |
| Middle Columbia River | 340 | Columbia River Gorge, numerous dams |
| Lower Columbia River | 433 | Major ports, shipping lanes, mouth of the river |
