In mid-September 1805, the Lewis and Clark Expedition reached the historic Lolo Trail. The Corps knew the Lolo Trail would provide them a physical challenge, and they feared they would not survive the peaks without assistance. They were able to acquire as many horses as possible and enlist the help of a few guides who knew the route that lay ahead. Under the guidance of Old Toby (Shoshone), the Corps turned northward and began their ascent into the Bitterroot Mountains.
Over the course of 11 days they walked a 200-mile stretch of mountain terrain. They suffered from frostbite, malnutrition and dehydration. Clark noted, "I have been wet and as cold in every part as I ever was in my life, indeed I was at one time fearfull my feet would freeze in the thin Mockirsons which I wore" (DeVoto 1997, 240). They pushed forward, nearing the end of the Trail. Capturing the moment, Lewis wrote:
“. . . the pleasure I now felt in having tryumphed over the rockey Mountains and decending once more to a level and fertile country where there was every rational hope of finding a comfortable subsistence for myself and party can be more readily conceived than expressed, nor was the flattering prospect of the final success of the expedition less pleasing . . .”
Exhausted and starving, the men stumbled out of the Bitterroot Mountains and encountered the Nez Perce Indians at Weippe Prairie. On their return trip, the Corps of Discovery again traversed the Lolo Trail - this time taking 15 days.
