Acadia National Park: Written in Rock

What happens when liquid fire and freezing ice combine? This unique landscape was formed from a volcano deep inside Acadia National Park that never erupted. This is how Acadia's pink granite is explained - and if you visit, you'll see that this pink glittering rock is everywhere! Glaciers got to work once this granite was formed, and like a slow bulldozer, formed this beautiful area and deposited an enormous boulder (Bubble Rock) along the way!
