Speaking of years, our first stop in the park was to see a few of the many fossil remains which have been found in the park. The Badlands has one of the highest concentration of fossils in the world. At one time the land was under a sea which teemed with life, the remains of that life can be found in the grayish-black sedimentary rock called shale. Years later the area became a dense subtropical forest and an array of now extinct animals ranged the land. We walked on a boardwalk which had replicate casts of those bones.
Years passed and the forest gave way to a savannah, which later became a grassland. Fossilized soils refer to the climatic history of the Badlands and they also speak to the colorful banding of the park's rocks. Pink and yellow stripes can be seen in the rock formations below.
