This is a long-exposure landscape photo of a mountain stream in Great Smoky Mountains National Park, Tennessee, USA. The soft flowing water cascades down moss-covered rocks to form small waterfalls. The tender green broad-leaf branches in the foreground add vivid vitality to the waterscape, surrounded by dense native evergreen vegetation. The park is a famous nature reserve in southeast US, well-known for its abundant rainfall and lush forest ecology, a popular destination for hiking and nature photography.
