Sunrise Over Fossil Hills Trail, Agate Fossil Beds National Monument

Sunrise sky over softly lit cement sidewalk style hiking trail. The trail slopes up and to the right around a hill. Several rolling grassy hills and a couple distant trees to right at Agate Fossil Beds National Monument.

In the early 1900s, paleontologists unearthed the Age of Mammals when they found full skeletons of extinct Miocene mammals in the hills of Nebraska -- species previously only known through fragments.

At the same time, an age of friendship began between rancher James Cook and Chief Red Cloud of the Lakota.

These two unprecedented events are preserved and protected here... at Agate Fossil Beds.
