While the expedition did not directly navigate the Gallatin River, they recognized its significance as one of the primary sources of the Missouri. The river’s pristine waters and natural beauty left a lasting impression on the Corps of Discovery.
3.2 The Madison River
The Madison River, named after James Madison, the Secretary of State during the expedition, is the central of the three rivers that converge at the Three Forks. This river flows through a canyon characterized by steep cliffs, rugged terrain, and challenging rapids.
Like the Gallatin River, the expedition did not directly navigate the Madison River, but they acknowledged its importance as a major contributor to the Missouri River’s flow. The river’s turbulent waters and dramatic landscape served as a reminder of the untamed wilderness they were exploring.
3.3 The Jefferson River
The Jefferson River, named after President Thomas Jefferson, is the westernmost of the three rivers that form the Missouri. This river was chosen by Lewis and Clark as the continuation of the Missouri, guiding them further into the uncharted territories.
The Jefferson River presented a narrower and shallower channel than the lower Missouri, requiring the expedition to adapt their navigation techniques. They relied more heavily on poling and towing, as the river’s currents made rowing and sailing difficult.
4. The Salmon River: The River of No Return
The Salmon River in Idaho, aptly named the “River of No Return,” presented a formidable challenge to the Lewis and Clark Expedition. Known for its treacherous rapids, narrow canyons, and powerful currents, the Salmon River proved to be impassable for the Corps of Discovery.
Captain Clark’s reconnaissance mission on August 19, 1805, confirmed the Salmon River’s unsuitability for navigation. The expedition concluded that attempting to navigate the Salmon River would be too risky and time-consuming, forcing them to seek an alternative route to the Pacific Ocean.
4.1 The Salmon River’s Reputation
The Salmon River’s reputation as the “River of No Return” stemmed from its challenging and unforgiving nature. The river’s powerful currents and numerous rapids made upstream travel exceedingly difficult, if not impossible.
Many early trappers and explorers who ventured into the Salmon River’s canyon found themselves unable to return upstream, earning the river its ominous nickname. The Lewis and Clark Expedition recognized the validity of this reputation and wisely chose to avoid the Salmon River.
4.2 Impact on the Expedition’s Route
The Salmon River’s impassability had a significant impact on the Lewis and Clark Expedition’s route. Forced to abandon their plans to navigate the Salmon River, the expedition had to find an alternative path through the rugged Idaho mountains.
This detour led them to the Lolo Trail, a treacherous mountain path that crossed the Bitterroot Range. The Lolo Trail proved to be one of the most arduous and challenging segments of the entire expedition.
5. The Clearwater and Lochsa Rivers: Navigating the Lolo Trail
The Clearwater and Lochsa Rivers played a crucial role in the Lewis and Clark Expedition’s journey through the Idaho wilderness. These rivers, located near the Lolo Trail, provided essential transportation and sustenance for the Corps of Discovery as they navigated the challenging mountain terrain.
