Describes how it was to live as a pioneer on the Oregon Trail.

The integral part the Oregon Trail had in the westward expansion of the United States is described in graphic illustrations.

Traveling with his owners from Missouri to Oregon in 1848, Koda, an energetic two-year-old quarter horse, finds the long journey increasingly tedious and tiring until his young owner goes missing on the trail and he must use all his skills to find her.
