This is a classic mountain waterfall landscape in Glacier National Park, Montana, USA, shot with long exposure technique. The silky cascading stream falls step by step along layered rock platforms, with large dark gray boulders scattered in the foreground. Both banks are covered with dense evergreen coniferous forests and bright green alpine meadows. Unmelted snow remains on the steep distant peaks, with clouds and blue sky echoing each other. Listed as a UNESCO World Heritage Site, the park shows the grand vitality of North American original wilderness.
