The Appalachian Mountains are a prominent mountain range in the northeastern United States, offering significant geographic, ecological, and cultural influence on the region.

One of the most distinctive geographical features of the northeastern United States is the Appalachian Mountains, which stretch from Canada to Alabama. In addition to having lush forests, undulating hills, and picturesque pathways like the well-known Appalachian Trail, this ancient range is abundant in species. Northeastern states like New York, Pennsylvania, and Vermont are greatly impacted by the range in terms of their economy, culture, and environment. In the past, the Appalachians were essential for trade routes and settlement; today, they draw hikers, tourists, and nature lovers. The Appalachians are recognizable due to their rounded, worn summits and vivid fall foliage, which sets them apart from the Rocky or Sierra Nevada mountains.
