The Appalachian Mountains span over 2,050 miles from Newfoundland, Canada, to Alabama, USA, even crossing into Saint Pierre and Miquelon (France). These ancient mountains, older than the Rockies, boast Mount Mitchell in North Carolina as their highest peak at 6,684 ft. Formed over 1.1 billion years ago by colliding continents, they feature a rugged landscape of ridges and valleys, historically a barrier to east-west travel. Today, they’re renowned for outdoor recreation, especially the 2,175-mile Appalachian Trail, offering stunning scenery and a connection to a rich geological and cultural history.Wikipedia
