There is so much rich history across the National Park System, from chapters of the Revolutionary War held in parks in the eastern half of the country to stories from the gold rush that stampeded through Alaska during the late 1890s.   This is Kurt Repanshek, your host at The National Parks Traveler. I’ve always been fascinated with history. And when you look at parks in the eastern half of the country, the reservoir is so much deeper than in the western half if only for the reason that more was written down.   Michael Aday has a similar passion for history, and has a great job to soak in it. He is, after all, the archivist or librarian at Great Smoky Mountains National Park. Recently he came out with a book, Letters from the Smokies, which is built around 300 years of written down history that’s held in the park’s archives.
