Lolo Trail, Idaho: September 12-21, 1805

The Shoshone provided the expedition with horses, a guide, and sound advice to help them through what was probably the most treacherous portion of their journey. The trail they followed across the divide and through the Bitterroot Mountains was extremely rugged. Game was scarce, which made the situation even more difficult for the explorers.
