Traveler's Rest was a stopping point of the Lewis and Clark Expedition, located about one mile south of Lolo, Montana.

Significant archeological findings made in 2002, including latrine sites with traces of mercury and fire hearths, make this the only site on the Lewis and Clark National Historic Trail that has yielded physical proof of the explorers' presence.

[5] From this location, Lewis and Clark split up to explore Montana during their return trip, not reuniting until they reached Sanish, North Dakota.

[8] After departing here in 1806, Lewis' part of the expedition traveled to what is now the Alice Creek Historic District.

Detailed historical and scientific investigations resulted in a 55-page request for boundary corrections, submitted on May 10, 2004, and approved on March 21, 2006.
