This formation of large limestone pillars is called Castle Rock. It is located on private range land in Gove County, Kansas. The limestone, chalk and shale formation is fragile and may not last many more years. The tallest spire fell after a thunderstorm in 2001. The chalk was deposited in the area by an ancient inland sea. The shape of Castle Rock and other formations in the adjoining badlands are due to weathering by wind and water. I thought the sun added a nice touch to the fascinating landscape.
PS – The road around the castle formation and adjoining badlands is no more than a two-rut path. It is very rough, so please keep that in mind if you plan to visit!
