The journals of Lewis and Clark record that on July 27, 1806, a Blackfeet Indian chief was killed in an encounter with that now famous expedition. In the same journal, a few pages earlier, is a reference to an unnamed white man who was living with the Blackfeet a few miles away.

This is his story.

His name was Yellow Hair, and that killing changed the entire course of his life - sending him on an exciting and daring mission across the unmapped wilderness.
