The Great Smoky Mountains are famous for their dense fogs and mist, which create their iconic smoky appearance.

The Great Smoky Mountains are renowned for their frequent fogs and mist, which are caused by the high humidity levels and temperature fluctuations in the area. As warm, moist air from the Gulf of Mexico rises, it cools and condenses, creating the fog that gives the mountains their "smoky" appearance. This phenomenon is particularly prominent in the mornings and is a distinctive feature of the region's natural beauty. It also plays a significant role in maintaining the area's lush temperate rainforest ecosystem.
