Flint Hills

The Flint Hills, historically known as Bluestem Pastures or Blue Stem Hills, are a beautiful area of hills and prairies mainly found in eastern Kansas. The name comes from the lots of flint that can be found near the surface there. This region stretches from Marshall and Washington counties in the north all the way down to Cowley County, Kansas, Kay, and Osage counties in Oklahoma, and from Geary county to Shawnee county to the east.

What makes the Flint Hills special is that it has the most intact tallgrass prairie left in North America. The soil there is rocky, so early people could not farm it easily. Because of this, many cattle ranches were started instead of farms, which you often see on the Great Plains. These ranches still use a careful kind of fire called a controlled burn every spring. This helps the grass grow better for the cattle to eat.

There is also a place called the Flint Hills Discovery Center in Manhattan, Kansas. It is a museum where you can learn all about the history and science of this amazing place. It opened in April 2012 and is a great spot for anyone interested in nature and history.

Description

Explorer Zebulon Pike first used the name "Flint Hills" in 1806. He wrote in his journal about passing through very rough flint hills. The hills are made of a special kind of limestone that contains flint. The biggest town in this area is Manhattan, Kansas. You can drive through the hills on the Flint Hills Scenic Byway.

Geology

The rocks in the Flint Hills were formed about 250 million years ago during the Permian Period. At that time, much of the Midwest, including Kansas and Oklahoma, was covered by shallow seas. This is why the Flint Hills are made mostly of limestone and shale, with many fossils of ancient sea creatures.

One important layer of limestone in the area is called the Florence Limestone Member. It is about 45 feet thick and can be seen along Interstate 70 in Riley County, Kansas. The Flint Hills have many hills because the limestone weathers away, leaving behind chert gravel on the hilltops. The highest point in the Flint Hills is Butler County High Point, which stands at 1,680 feet above sea level.

Environment

The Flint Hills are special because the soil has limestone and chert just below the surface, making it hard to grow crops like corn and wheat. Instead, people raised cattle there, which helped keep the land wild.

Because the land was never plowed and has few buildings, the Flint Hills hold the largest areas of tallgrass prairie left in the United States. These prairies are important for protecting plants and animals that used to cover much of the Great Plains. Fires and grazing help keep the prairie alive by stopping trees and shrubs from growing too much.

Animals like the American bison, which once lived there by the millions, have been brought back to the area. The Flint Hills are recognized as a special place by groups that protect the environment.

There are four preserves in the Flint Hills where people can learn about tallgrass prairie. The largest is the Tallgrass Prairie Preserve in Oklahoma, home to many bison and other wildlife. Other preserves in Kansas include the Tallgrass Prairie National Preserve, the Flint Hills Tallgrass Prairie Preserve, and the Konza Prairie, a research area managed by Kansas State University.

In popular culture

William Least Heat-Moon wrote a book called PrairyErth that celebrates the Flint Hills and the people who live there.

In the world of math, there is something called the Flint Hills series. This is a special kind of endless adding that scientists are still trying to figure out if it will ever end or keep going forever. Its answer is connected to how we understand the number π.
