Near Bar Harbor in Hancock County, Maine — The American Northeast (New England)
Volcanic Landscape Exposed
Acadia National Park
You are standing on granite rock formed millions of years ago when a very hot liquid cooled deep below the Earth’s surface. Trapped in a magma chamber more than two miles deep, the 1,652°F (900° C) liquid crystallized into the mineral rich, pink Cadillac Mountain granite. Eventually erosion and glaciers scoured and removed the softer, overlying rock, revealing the harder, more resistant granite – Acadia’s mountains.
Most of Mount Desert Island is composed of Cadillac Mountain granite.
