This is a landscape photography work of Grand Canyon at sunset in the USA. The foreground features a dark silhouette of an ancient pine on the cliff, with twisted roots exposed on the gravelly desert ground. Thick clouds half cover the setting sun, warm golden sunlight penetrates cloud gaps to form clear Tyndall beams, spreading over the layered canyon rock walls and distant mountain outlines. The interweaving of cold and warm tones fully shows the magnificent natural features of Grand Canyon, presenting a quiet and extremely shocking atmosphere.
