Near Gibbonsville in Lemhi County, Idaho — The American West (Mountains)
Lost Trail Pass
“hills high & rockey on each Side, in the after part of the day the high mountains closed the Creek on each Side and obliged us to take on the Steep Sides of those Mountains, So steep that the horses could scarcely keep from slipping down, several sliped (sic) & injured themselves verry (sic) much, with great dificuelty (sic) we made (8) miles & Encamped on a branch of the Creek. . . “ -- Captain Clark, Sept. 3rd, 1805
Imagine a time when no highway was here. Which way would you chose to get over the mountains? Although they had Toby to guide them, making their way over these steep and formidable mountains made the days between August 31, and September 4, 1805 some of the most difficult days of the entire journey for the Corps of Discovery.
Based on descriptions from the journals it is easy to reconstruct most of the route Lewis and Clark followed. But on this section of the trail, scholars and aficionados have long disagreed. Neither the rugged countryside nor the journal entries gives a clear indication of the path they followed. While there is some consensus about the probable camp sites of September
There are few places along the Lewis and Clark trail where the exact route has been open to so much speculation. In this rugged country where no way seems clear and obvious, there were a variety of theories about which route was actually taken.
On July 11 and 12th, 1997, a workshop was held featuring five Lewis and Clark scholars. Each presented to nearly 70 attendees their own ideas of what happened between September 1st and 4th, 1805. Participants spent time locked in a room battling over individual interpretations and on the Pass reviewing the different routes and campsite locations. Using journal accounts and a variety of mapping tools, including computer modeling, experts finally agreed on the route south of where the North and West Forks of the Salmon River and Moose Creek come together, however, from that point north little consensus was reached.
