Le Glacier Gustave Courbet (1819-1877)

The picture has something of this: landscape, water, mountain, tree, scenic, daylight, outdoors, rock, river, volcano, environment, eruption, park, nature, fog, seashore, sky, valley.
Perhaps it’s a painting of a mountain scene with a river in the foreground and a castle in the middle of the picture on the right side of the painting.
