Landscape from La Source Bleue Gustave Courbet (1819-1877)

The picture has something of this: water, river, tree, nature, landscape, waterfall, wood, rock, outdoors, leaf, mountain, stream, lake, calamity, creek, rain, light, motion.
Perhaps it’s a painting of a cave in the middle of a forest with a body of water in the foreground and trees on the other side of the cave.
