20 million years ago, the surface of the plains was as high as Scotts Bluff - a gently sloping landscape composed of sediments from uplands to the west. About 5 million years ago, the Platte River and its tributaries began to erode the high plains. Bit by bit, water carried away massive volumes of soil and rock, creating canyons that grew wider and wider.

The West of the mid 1800s offered new beginnings to thousands of emigrants. In search of new freedom, many modes of transportation were used on the trails.

 Covered wagon migrations began in 1841. Emigrants bound to Oregon or California loaded possessions and provisions into small canvas-covered wagons. Two to four yoke of oxen pulled the wagon, while the family walked alongside.
