Adirondack Mountains

 Origins 
The Adirondack Mountains are not part of the Appalachian Mountains. They are a continuation of the Canadian Shield. Their origin is extremely ancient, dating back to the Mesoproterozoic era, in what is called the Grenville orogeny. After that old chain had been eroded away, recent uplifts  produced the mountains we see today.
