Great Bend in Barton County, Kansas — The American Midwest (Upper Plains)
Post Rock & Black Gold
Minerals Under the Prairie Sod
Imagine it's 1880, and you've just driven your family hundreds of wearying miles by wagon here to central Kansas. Youre anxious to build a house, but you're surrounded by unbroken prairie not a stick of construction-grade wood in sight. With what do you build?
Settlers quickly found the answer beneath their feet. First, they built their soddies with blocks of prairie earth. Then, they discovered a more durable building material limestone. Greenhorn limestone stretches beneath about three million acres of Kansas. This thin limestone layer, just 8-12 inches thick, yielded high-quality building material for homes, churches, bridges, and more. One common use for limestone was fence posts. Still visible along the Byway, limestone post rock once supported an estimated 40,000 miles of fencing in the state. Watch for the many enduring examples of native limestone handiwork as you travel the Byway.
Kansas Crude
The industrial heartbeat of this part of Kansas is the ka-thump ka-thump of pumping units sucking crude oil out of the ground. Pumps dot the landscape along much of the Byway. Oil production began in this part of Kansas around 1930, peaking in the 1950s. Oil and gas production remains important to the regional economy; in 2006, more than 3,200 oil wells and 177 gas wells operated in Barton and Stafford Counties.
Motion and Change
Can you smell the ocean? Well, maybe not now, but several times over the past 300 million years, you could have. Seawater brimming with corals, shellfish, and other marine life periodically submerged this land. As organisms died, they accumulated on the ocean floor. Over time and with pressure, shells became limestone and organic materials transformed into oil and gas.

(by Grace Muilenburg and Ada Swineford) Excerpt: Land of the Post Rock is a distinction given to about 3 million acres in North Central Kansas an area where a single bed of rock (the 8-12 Fencepost bed of the Greenhorn limestone layer) was used so extensively for fence posts during early Kansas settlement days that the posts have become an identifying feature of the landscape.(Submitted on June 13, 2026, by Cosmos Mariner of Cape Canaveral, Florida.)Settlers to Kansas found that the area was destitute of timber and turned to the material at hand a layer of rock close to the surface that they soon found could be used for fencing as well as building. Besides being durable and fire resistant,
this limestone had several other advantages. Being close to the surface it could be obtained easily with the proper tools and techniques. It was uniform in thickness (8-12). It was persistent, extending with little interruption for miles. And when freshly quarried it was soft enough to shape with tools and hardened after being exposed to air.There were of course disadvantages. Quarrying rock in post length required skill, hard work, and time. Once split out and shaped they had to be transported. This again required hard work and ingenuity as each 5 to 6 ft long post weighed about 350-400 lbs.
