In the Appalachian Mountains, several notable gorges can be found, such as the New River Gorge in West Virginia. These gorges often feature dramatic cliffs and deep ravines, providing stunning vistas and recreational opportunities like hiking, rock climbing, and whitewater rafting. The formation of gorges in the Appalachians highlights the region's dynamic geological history and natural beauty.
