Hocking Hills

More than 330 million years ago, the area was relatively level and covered by the waters of the Atlantic Ocean. For millions of years, the ocean's currents deposited immense amounts of sand and gravel. After millions of years, the ocean receded, and the sandy layers bonded with silica to form the Black Hand Sandstone that underlies the area. It formed like a sandwich, with a hard top and bottom and a soft middle layer. When the Appalachian Mountains arose, form and feature were cast upon the area and created the Hocking Hills.
