National Geographic: Lewis & Clark - Great Journey West

"This National Geographic title explores the historic work of Lewis and Clark. The special comes to DVD with a standard full-frame transfer that preserves the original aspect ratio of 1.33:1. The English soundtrack is rendered in Dolby Digital 5.1. There are no subtitles, but the soundtrack is closed-captioned. Supplemental materials include a making-of featurette, and an interactive map of their journey. This is a fine disc for those with an interest in the subject matter as well as for teachers who may find it useful in a classroom setting."
