This region contain rocks from the Rocky Mountains that were carried east by the Arkansas River. When the river loses much of its water on the High Plains, it dumps sediment in this region. Over time, the sediment becomes rock.

Low hills topped with sandstone make up this region. Water once flowed to an inland sea, and sand collected at the mouths of the rivers. As the sand was buried and put under pressure, sandstone formed. Over time, erosion exposed rock formations called outcroppings. Hardwood trees, such as oaks, and medium-tall grasses cover this region.

Fertile soil makes this region beneficial for agriculture. A long time ago, this area was swampland. Dead plants fell into the water, eventually turning to coal. Coal mining became part of this region's history. Today it is a gently rolling landscape.

This region is a well-known ranching area. The erosion of limestone and shale formed its rolling hills. The limestone contains flint, a hard gray mineral that creates a rocky soil. There are few trees, except near the streams. This region is one of the last tallgrass prairies in the United States.

Huge glaciers over 500 feet thick once covered the northern part of the United States. As the ice moved south, it broke off boulders and deposited them in Kansas. These red quartzite boulders can be seen today in these regions.

Over time, parts of the Rocky mountains eroded into sand and rock. Water carried the debris east and deposited it on the High Plains. Outcroppings of sandstone can be found among the desert plants on the flatlands This region stretches into eastern Colorado.

Meaning the Spanish word for hill or cliff. This region contains east-facing cliffs with gentle slopes to the west. The slopes contain layers of shale, or soft sedimentary rock that is formed with mud or clay. The ridges are 50-200 feet high and are surrounded by prairie.

This region extends into Missouri, Oklahoma, and Arkansas. It has the oldest surface rock in the state. The limestone here formed millions of years ago when this region alternated between being below the seas and above it. The land is hilly and covered with hardwood trees. Caves can be found in this region.

This region get their name from the iron oxide (rust) that colors them a dark red. These land formations are also referred to as the Gypsum Hills. Plains Indians believed in the healing powers of the hills and streams. The magnesium sulfates found in the water are better known as Epsom salt and are used to heal wound today.

This region gets its name from the haze in the valleys early in the morning. Many years ago, this region was under an ocean that created the sandstone, limestone, and chalk found there today. Hills appear to grow out of the surrounding plains.

This region contain sand dunes covered with grasses. Under the ground are two important resources: water and salt. The Hutchinson salt bed is one of the largest salt beds in the world.
