From Wikipedia
The Taconic orogeny was a mountain building period that ended 440 million years ago (Ma) and affected most of modern-day New England. A great mountain chain formed from Eastern Canada down through what is now the Piedmont of the east coast of the United States. As the mountain chain eroded during the Silurian and Devonian periods, sediment spread throughout the present-day Appalachians and midcontinental North America.
