Agate Fossil Beds National Monument - http://www.nps.gov/agfo

Agate is an internationally recognized fossil site. However, as a place, Agate is so much more. The landscape surrounding the fossil beds has been a site of change for millions of years. The relationship between land, weather, ecology and mammals in the Agate area has been a stage of continual change over time.
Agate has also been a home to people like James Cook and his wife, Kate; great leaders of great nations like Red Cloud and American Horse. A place where people have lived, raised families and died. The record that is preserved in this cultural landscape not only reflects the diverse history of change and evolution, but also the struggles of existence in a region with so many extremes.

Agate is also a place of interaction, reflective of both the natural and cultural realms. For Agate has been a meeting place between weather and sediment; the exchange of ideas and memories between cultures; and a site for present generations to make contact with the past. It's a place where tangible reminders of these interactions are present everyday. The weathering of sedimentary rock, bones becoming visible in cliffs, and the gifts presented to James Cook by the Lakota Sioux are all reflective of the strong natural and cultural relationships of the Agate landscape.
