Snow-covered trees lit by the sun in the foreground of this image from the Look Rock Observation Tower in Great Smoky Mountains National Park. The mixture of sun and clouds has created interesting patterns of light and shadow on the mountain slopes behind the trees, almost as if some form of precipitation was falling despite the predominantly blue sky overhead. Some of the slopes have snow and some of the higher peaks, especially those in the distance, appear to be masked by passing clouds. The blue sky, which fills the upper half of the image, has an assortment of white and silver-grey clouds
