America’s last tallgrass prairie is in Kansas and bison have been running it the whole time

Where bison roam and limestone tells the story

You can drive 47 miles across Kansas and see a landscape that has barely changed in thousands of years.

The Flint Hills National Scenic Byway runs along Highway 177 between Council Grove and Cassoday, cutting through one of the last patches of tallgrass prairie left in North America. Bison graze the hills.

Limestone holds up a 150-year-old courthouse. And the road takes you straight into a story that started 280 million years ago.

The road that cuts through 280 million years

The byway runs 47 miles down Kansas Highway 177, from Council Grove south to Cassoday, on a two-lane paved road that crosses Morris, Chase, and Butler Counties.

Tallgrass prairie once spread across 170 million acres of North America. Less than 4 percent survives today, and most of what’s left sits right here in the Flint Hills.

The land looks much like it did when the Kanza and Osage lived on it. Tune your radio to 1680 AM and the prairie tells you its own history as you drive.

Why a plow could not break this land

The hills are made of limestone laid down by a shallow sea about 280 million years ago. The soil on top is thin and rocky, and that one fact saved the prairie.

Crop farmers took one look and kept moving. Cattle ranchers stayed, and the native grass stayed with them.

Native Americans were the first to set the prairie on fire to pull bison toward fresh shoots, and ranchers still light prescribed burns each spring in late March and April.

Without those fires, woodland would swallow the prairie in about 30 years.

Council Grove sits where the wagons gathered

At the byway’s northern end, Council Grove holds more than 24 historic sites tied to the Santa Fe Trail.

The town got its name from a stand of trees where, in 1825, U.S. commissioners and Osage chiefs sat down under a large oak and signed a treaty granting free passage along the trail.

From here, wagon trains rolled west toward Santa Fe across hundreds of miles of open prairie, and Council Grove was the last place to load up on supplies before the country went empty.

The oak tree that delivered the mail

From 1825 to 1847, the Post Office Oak worked as a mailbox for the Santa Fe Trail. Travelers tucked notes into a hole at the base for the wagons coming behind them.

The tree died in 1990, but the trunk still stands next to the Post Office Oak Museum.

Main Street follows the old wagon road, and the Neosho Riverwalk links you to one of the most documented river crossings on the trail.

The Madonna of the Trail statue, dedicated in 1928, honors the pioneer mothers who pushed west in covered wagons.

The tribe that gave Kansas its name

The Kaw, also called the Kanza, gave the state its name. In 1846, a treaty pushed the Kaw onto a 20-square-mile reservation near Council Grove.

Five years later, the Methodist Episcopal Church South built the Kaw Mission as a school and boarding house for 30 Kaw boys.

The school shut down in 1854, but the stone building still stands, now a museum run by the Kansas Historical Society.

It’s one of the oldest buildings still on its feet anywhere in this part of Kansas.

An 11,000-acre preserve unlike any other

Drive south and you’ll hit the Tallgrass Prairie National Preserve, nearly 11,000 acres of open grassland set aside on November 12, 1996.

It’s the only piece of the National Park System dedicated to the tallgrass prairie. The arrangement is unusual, too.

The National Park Service owns about 33 acres. The Nature Conservancy owns the rest, and the two work together to keep the place running.

More than 40 miles of hiking trails cross the prairie, so you can walk for a whole day and barely see the road.

Bison came back after 100 years gone

In 2009, 13 bison from Wind Cave National Park in South Dakota came home to this land. They were the first bison to walk these hills in more than a century.

The herd does real work for the prairie. Their grazing scatters seeds, opens space for different plants, and keeps the grass at heights other wildlife needs.

You can often spot them in the Windmill Pasture area. Seasonal guided tours run deeper into the prairie, where rangers take you out for a closer look at the herd.

The limestone ranch that started it all

The preserve sits on the bones of the old Spring Hill Ranch, started by cattleman Stephen F. Jones in 1878.

Three years later, in 1881, he finished a Second Empire-style ranch house built from local Cottonwood limestone. A three-story limestone barn rises nearby, big enough to make you stop and stare.

Jones also donated land for the Lower Fox Creek School, a one-room schoolhouse that still stands. You can take self-guided tours of the historic buildings starting at the preserve’s visitor center.

A spiral staircase carved from local walnut

In Cottonwood Falls, the Chase County Courthouse has been doing business since 1873, making it the oldest working courthouse in Kansas.

Architect John G. Haskell, who also drew up the Kansas State Capitol, designed it in French Renaissance style. The limestone came right out of the ground at the town site.

Inside, a three-story spiral staircase climbs through walnut pulled from local trees. The whole building stands 113 feet tall with a red mansard roof you can spot from miles across the county.

It joined the National Register of Historic Places in 1971, and you can walk through during business hours.

The view that opens up south of Cottonwood Falls

About 3 miles south of Cottonwood Falls on K-177, the Schrumpf Hill Scenic Overlook gives you the widest look at the prairie on the whole byway.

Paved walkways and interpretive panels lay out the names of the plants and animals stretched out below.

South of the overlook, the road climbs the hills and drops into creek bottoms walled by limestone, with old farmsteads still working the land.

Near Matfield Green, the Pioneer Bluffs Historic District preserves a Flint Hills ranching homestead from the inside out.

When the prairie burns at night

Every spring, ranchers across the Flint Hills time their prescribed burns so the hills light up in slow waves. The fires clear out dead plant matter and stop invasive trees like eastern red cedar from taking root.

The native grasses don’t die because their roots reach 12 feet underground, far below the heat. The whole tallgrass system supports more than 500 species of plants.

About 2.2 million acres burn each year on average across the Flint Hills of Kansas and Oklahoma, and the night sky glows orange when the season hits.

A town of 113 known for booming chickens

At the south end of the byway, Cassoday counts just 113 people as of the 2020 census. Locals call it the Prairie Chicken Capital of the World.

Each spring at dawn, male greater prairie chickens fan out colorful air sacs and perform a mating display called booming.

The old railroad depot now houses the Cassoday Historical Museum.

The Cassoday Bike Run rolls in on the first Sunday of each month from March through October, when motorcycle riders from across the region pull into town and fill the streets.

Visiting the Tallgrass Prairie National Preserve in Kansas

You’ll find the preserve 2 miles north of Strong City, Kansas, right on the byway at K-177.

Admission is free, and the visitor center runs a 10-minute park video along with exhibits to get you oriented. From there, you’ve got nearly 11,000 acres and over 40 miles of trails to explore.

Seasonal guided tours take you deeper into the prairie to see the bison, and you can self-tour the Spring Hill Ranch house, the three-story limestone barn, and the Fox Creek Schoolhouse.

The preserve stays open year-round.
