The Clark Fork River is a major river in western Montana, flowing approximately 310 miles. It originates from the confluence of the Flathead River and the Little Blackfoot River, eventually emptying into the Columbia River near Lake Pend Oreille in Idaho. The river is known for its scenic beauty and diverse ecosystems, making it a popular destination for outdoor activities such as fishing, rafting, and hiking. Historically, the Clark Fork River played a significant role in the development of the region, particularly during the Gold Rush in the 1860s. The river was named after William Clark, one of the leaders of the Lewis and Clark Expedition. Today, it remains an important waterway for both recreation and wildlife habitat.
