Late Autumn Fog Over River Valley

Thick marine fog blankets a river valley in early autumn, obscuring the forest floor and rising in soft, uneven layers. The low-hanging clouds merge with the mist, creating a seamless gray horizon beneath a late afternoon sky. Sunlight reflects off the dark water, casting a muted, silvery sheen that breaks through the dense air. Textures shift from the smooth surface of the river to the rough, indistinct shapes of submerged trees. The perspective looks down from above, revealing the valley as a shadowed basin where light and fog compete for dominance. A faint line of darker green foliage marks the valley edge, standing out against the pale, swirling vapor.
