We're atop the pass that the Corp of Discovery used back in 1805. [The Shoshone had used it, crossing on horseback, but for not as long as I would have thought.] While this point now represents the Idaho/Montana border, it was then that between the United States (Louisiana Purchase) and land claimed by the British.
I was working west to east here and the photographs are in the order in which I took them...
The first image was made looking westward: Agency Creek emanates from this spot and flows first to the Lemhi River and then to the Salmon River, Snake, and Columbia Rivers. Lewis hoped this would be their route to the Pacific—but it was not to be.
The second image was made at the peak: there is plenty of interpretive signage here, well worth the drive up (from either direction) using gravel roads. Since this is the land of the Shoshone, there is a memorial area set aside for Sacagawea who helped guide the Corp of Discovery through this area on their way to the Pacific.
The third image was made looking eastward: it shows the approach Meriwether Lewis and three others from the party first made a scouting trip over the Great Divide. They would return to Camp Fortunate to parlay with Shoshone, gather up Clark and the others (including Sacagawea), and cross over again two weeks later.
