Autumn mountains rise around a forested valley where a winding stream runs through the trees. The scene includes wooded hills, fallen leaves, and open sky with layered clouds above the valley. Sun rays pass through the cloud cover and illuminate sections of the forest and water, while light fog remains near the distant slopes. The stream forms a visible line through the lower part of the valley and connects the foreground water with the mountain slopes beyond the trees. The composition presents a natural landscape with mountains, forest, stream, sky, clouds, leaves, and seasonal autumn color.
