Places We Protect

Smoky Valley Ranch


Vast shortgrass prairie marked by chalk badlands that contain fossil records 85 million years old.

On this land, you'll view a sight that almost vanished from America—bison roaming a prairie as they did hundreds of years ago. Dramatic chalk bluffs overlook large expanses of grassland, rocky ravines and Smoky Hill River. Breaks along the upper reaches of the river represent a transition zone between mixed grass and shortgrass prairie environments. When The Nature Conservancy purchased Smoky Valley Ranch in 1999, it was the largest land acquisition for conservation in state history. At that time, several parcels had been carved out of the ranch, sold to other buyers and converted to cropland. In 2020, the final piece was purchased, making the 18,000-acre ranch whole again.

This prairie supports tremendous plant and wildlife diversity while continuing its long history as a working cattle ranch. In western Kansas, 80% of the native prairie has been converted to some other use. Demonstrating that healthy wildlife populations and successful ranching operations go hand-in-hand is critical to retaining the 20% of the prairie that's left. 

Hiking and horseback trails on the western edge of Smoky Valley Ranch are open year-round. Prairie vistas and chalk bluffs greet hikers as they wind their way around the two trail loops. The first loop is one-mile hike, the second loop is five-mile hike. Please see below for directions to ranch and trail map and instructions. Because of the rough terrain, boots are recommended. Any items brought in like water bottles or food wrappers must be taken out.

While You're in the Area

Western Kansas is full of culturally and visually fascinating things to see and do.  We suggest you start with the Western Vistas Historic Byway route.

And no visit to Smoky Valley Ranch is complete without a stop at the nearby Little Jerusalem Badlands State Park.

100 Million Years Ago: Much of modern-day Kansas is covered by the vast inland sea that splits North America into two land masses.

66 Million Years Ago: The Western Interior Seaway begins to recede, leaving the carbonate deposits throughout the region that we know as the chalk bluffs and Niobrara Chalk formations.

15,000 Years Ago: Paleo Indians occupy the region and hunt ancient bison by running them off cliffs at Twelve Mile Creek. Bison antiquus were 15-25% larger than the modern Bison bison. Over the next 10,000 years, the climate warms and becomes more arid, megafauna populations decline and human activity in the area around Smoky Valley Ranch greatly decreases

Pre-19th Century: Cheyenne, Arapaho, Pawnee, Comanche and Kiowa tribes inhabit the Smoky Valley River valley.

1854: Kansas territory is opened for European settlement.  Conversion of native prairie for crop production begins on a large scale.

1879: The last wild bison in Kansas is killed near Elkhart.

1885-1905: More than 100 families of African-American settlers put down roots on and around the ranch in Logan County. Many of the settlers have ties to the town of Nicodemus, the only remaining free black settlement in the state at that time.

1900s: Noah Ziegler a veteran cowboy began ranching at what is now known as Smoky Valley Ranch in 1884. Since that time, a succession of ranchers grazed the land with cattle and sheep.

1999: The Nature Conservancy purchased Smoky Valley Ranch from a collective of willing sellers to protect the land and keep the ranch intact. The following year, bison are reintroduced to the ranch.

2007: Black-footed ferrets, North America's most endangered mammal, are reintroduced to the interior of the ranch.

2020: The final inholding is purchased by The Nature Conservancy, making the ranch whole again for the first time in 150 years. Sheep wire has been removed to allow pronghorn to pass through the ranch unimpeded.
