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.

Thank you for abiding by the following trail user guidelines:

  • Trail hours: daylight only. Plan your hike to be off trail by sunset.
  • Stay on the trail. Please do not leave the trail corridor or take shortcuts.
  • No bicycles or motorized vehicles.
  • No firearms.
  • No camping or campfires.
  • No smoking or alcoholic beverages.
  • Keep dogs leashed.
  • Leave nothing but footprints. Please do not litter.
  • Take nothing but pictures. Collecting of anything from the ground is not allowed. If you discover artifacts or fossils, please leave them and notify us at or 785-233-4400. 

There is no restroom or water provided. There are rattlesnakes in this area, so wear boots and watch where you walk, especially in the early morning and late evening. Note the two trees to the west of the trailhead—a good trailhead landmark that can be seen from any high point along the trail. Your cell phone coverage on the trails might be weak and spotty.

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.

Live LekCam Live stream of one lesser prairie-chicken leks at Smoky Valley Ranch. Males will typically be active for a few hours in the morning and evenings. Camera will live stream 6-10am and 6-9pm central daily through mid-May. Scroll back to earlier footage if there's no action when you tune in.

Each spring, male lesser prairie-chicken (Tympanuchus pallidicinctus) face off at sunrise, competing to be selected to mate with awaiting females. The battles are more dance-off than fist-fight, and the opportunity to witness it is increasingly rare.

More than half of all lesser prairie-chickens in the world are now found in western Kansas, between the Arkansas River and northern reaches of the Smoky Hill River. This is where the ranges for greater prairie-chickens and lesser prairie-chickens come together, forming a small overlap that doesn't exist anywhere else in the world. This small area is also home to Smoky Valley Ranch where, this spring, 165 male prairie-chickens have observed attending 13 leks—the areas where the mating dances take place.

With suitable habitat in just five states (Colorado, Kansas, Oklahoma, New Mexico and Texas), lesser prairie-chickens were listed as Threatened under the Endangered Species Act in 2014. A lawsuit challenging the listing ended in a judge vacating the listing decision in 2015. Another petition for listing as Threatened was received in 2016, and a finding is expected in May 2021.

A few years ago, the Western Association of Fish & Wildlife Agencies developed a Lesser Prairie-Chicken Range Wide Conservation Plan to coordinate and guide conservation efforts. Matt Bain, western Kansas conservation manager for The Nature Conservancy, is a member of the science committee for that group along with the state of Kansas' implementation team. This plan identifies the 18,000-acre Smoky Valley Ranch as the only “partial stronghold” in western Kansas. (A “stronghold” for the species has been defined as at least 25,000 acres of high-quality habitat that is likely to be maintained in perpetuity.)

Smoky Valley Ranch is a critical, rare venue for one of the most important strategies for protecting lesser-prairie chicken: using grassland grazing techniques that encourage nesting and brooding habitat. The Nature Conservancy also works with other landowners in the area to help them improve conditions for prairie-chickens on their rangeland without sacrificing ranch profitability.

Lesser prairie-chickens are icons of the western Kansas prairie, requiring large tracts of contiguous grassland in an area where less than a quarter of the native prairie remains. The elusive, shy prairie-chicken is one symbol of the prairie that is in trouble. Known as an indicator species, if you have lots of prairie-chickens, then the prairie is in good shape—and the opposite is true. It is ranchers who are stewarding the vast majority of these last wild places in Kansas and protecting the wildlife species, like the lesser-prairie chicken, that depend on those places.

One example is the Conservation Reserve Program (CRP), a voluntary conservation program signed into law by President Reagan in 1985. In western Kansas, CRP provides landowners with cost-share and annual rental payments to restore native grassland on croplands susceptible to erosion and to restore wildlife habitat. And CRP's impact on lesser prairie-chicken populations is one of the most successful voluntary conservation success stories of our time. The larger area around Smoky Valley Ranch, between the Arkansas River and I-70 highway now holds 1/2 to 2/3 of all lesser prairie-chickens in the world. Prior to CRP, they were likely not in this part of Kansas at all.
