Created by a four-time Emmy-winning filmmaker, "The Story of the Oregon Trail" chronicles the great mid-1800s trek across the unsettled American West. One in ten pioneers died along the way; many walked the entire 2,000 miles barefoot; but in the end nearly a half-million Americans followed the ruts west in search of a better life. Rare photos, diary excerpts, and stunning footage tell a fascinating story of tragedy and triumph.
