The impossible Salmon River
August 23, 1805
At four miles we came to a place the horses could not pass without going into the river... I set out with three men directing those left to hunt and fish until my return... The river from the place I left my party to this creek is almost one continued rapid... Below my guide and many other Indians tell me that... the water runs with great violence from one rock to the other on each side foaming and roaring through rocks in every direction, so as to render the passage of any thing impossible...and the hills or mountains were not like those I had seen but like the side of a tree straight up.
