Lewis and Clark have intrigued travelers for over two centuries. And whether you are a Lewis and Clark “groupie”, someone who might enjoy stopping at a site or two on an upcoming trip, or an armchair traveler interested in a “rediscovery” of the corps’ exploration, this book provides visitor information and historical and cultural touchstones for Lewis and Clark’s travels from South Dakota to the Pacific and back. Obviously, in the 200+ years that have passed since their 1804-1806 expedition much of the land has changed, and, in many cases, the site the corps visited itself is literally gone, often under water. But the route itself remains, and this guide provides an opportunity to “rediscover” the corps’ footsteps.
