In 1804, Meriwether Lewis and William Clark set out on a journey into the American West. Their aim was to explore the Louisiana Territory, recently added to the United States by President Jefferson, to find a practical route across the continent, and to discover new people, plants, and wildlife.
Some say the hardest section of the journey was a 12-mile stretch between the borders of present-day Montana and Idaho. In his new book Lost Pass 1805, Ted Hall describes what he believes to the route they took, up the North Fork of the Salmon River.
According to a report by NBC Montana, Ted's colleague and fellow engineer Tim Lee helped research the book, using Google Earth to help check Ted's findings. Ted also located and drew on the work of James West Gallogly, an early settler in the Lost Pass area who investigated the route of Lewis and Clark independently a hundred years earlier.
On March 1, Ted spoke about the book and about Lewis and Clark at the Ravalli County Museum in Hamilton, Montana.
