Statement of Significance (as of designation - October 9, 1960):
When, after reaching Lehmi Pass and crossing the Continental Divide, navigation of the Salmon River proved impossible, Lewis and Clark determined to use one of several trails over the mountains used by the Nez Perce in their annual journeys to the buffalo plains in the east. The Lolo Trail, used by the explorers to cross the Bitterroot Mountains in September 1805, represents probably the most arduous single stretch of the entire route travelled by the expedition.

It may be close to time to upgrade status to satisfactory. Tribal and Forest Service monitoring is working reduce impacts. Threats from private logging and wild fire continue however. Wild fire imapcted segments last year.

It is unknown if there are changes since the last report.

Recommendation/Change since last report:
Because some of the trail remains in areas that are being actively logged this Landmark’s condition should remain at Watch.
