1. Agate Springs Ranch Marker
Inscription. Ample water from the Niobrara River, protective bluffs, and good grazing land made this an ideal place for a ranch. Established in 1879, it was one of the first ranches in the frontier territory of Sioux County. By the early 1900s, it encompassed over 2500 acres.

James Cook's ranch was also a way station for travelers and a destination for guests: Lakota families from Pine Ridge, local ranchers, friends from Wyoming and Colorado, and famous paleontologists eager to explore the fossil hills. The family home featured a museum displaying Cook's collection of Indian artifacts and fossils.

Today, Agate Springs Ranch is still a family-owned working ranch. Please respect the owner's privacy. A portion of James Cook's museum collection is on display at the Agate Fossil Beds National Monument Visitor Center.
