Have you ever traveled back in time — to the Quaternary Age, when wild lynx left their mark 333 feet below the Earth?

But as the original explorer, you’re prepared to give what you have to uncover this underground glory. And that glory, well, it comes in many different forms — from The Great Extension, the Monument Pillar, and the Blue Mud Mountain, to the Rock of Ages and undiscovered passages.
