Ripples in the Layers

Joints

We studied the joints and cracks in the layered rocks at Buttermilk park. We learned that the layers were formed first about 300 million years ago. Some cracks were made during the dinosaur age. Other cracks were formed by a chemical reaction from gas and oil. More space was required and that is what caused the cracks. Some of the other rocks were cracked when mountains were formed and continents moved.
