From about 400 to 300 million years ago the Iapetus Ocean gradually closed during subduction. But as the weight of the high mountains is reduced by erosion, the thick, buoyant crust bobs back upward (rebounds), creating topography not quite as high as it was before. What is the lowest peak in the Appalachian Mountains? Appalachian Mountains. Huge masses of rocks were pushed west- ward along the margin of North America and piled up to form the mountains that we now know as the Appalachians. The Appalachian Mountains occupy a towering spot in North American cultural identity, thanks in part to the Appalachian Trail. The range is sometimes called the Smoky Mountains and the name is commonly shortened to the Smokies. After 300 million years the mountains have eroded deeply and are covered in places by young sediments of the Atlantic and Gulf coastal plains. An ice-covered peak in the Himalayan range pokes through a blanket of clouds.
