The geologic story of Scotts Bluff National Monument began approximately 33 million years ago. At that time, as the Rocky Mountains were being uplifted to the west, sediments were being weathered and eroded out of those young mountains. Those sediments, sand and silt, were carried out of the mountains by wind and meandering rivers and began to accumulate on the floor of the Great Plains. Occasionally, volcanic eruptions to the west spewed ash into the air. Carried by the wind, the ash accumulated along with the other sediments in layer upon layer. At the same time, forces of weathering and erosion worked to break down the plains and carry them to the ocean.

This is a 1.6 mile (one-way) hike along the Saddle Rock Trail. The self-guided tour is set up to begin at the summit of Scotts Bluff. However, you can also begin at the lower trailhead which is located just east of the visitor center. There is an elevation change of 435 feet on this trail and no water is available along the trail. To get to the first stop, drive to the summit of Scotts Bluff and take the North Overlook Trail to the northmost overlook. There you will see a view that reaches across the North Platte River Valley.
