Geologic Time Machine activity for students
Pine Mountain forms the northwest boundary of the Cumberland Overthrust block. It is the upturned edge of the block where rock strata have been brought to the surface by displacement along the Pine Mountain Overthrust block. Displacement has caused the rocks to be tilted up at sharp angles. The exposed strata that we see today would normally appear about 2000 feet below the surface of the earth. The movement occurred about 270 million years ago in the Permian period when the Appalachian Mountains were being formed by continental plate collision. Resistant sandstones in the Pennington and Lee formation were deposited 315 to 325 million years ago.*
