Norwegian Landscape Johan Christian Clausen Dahl (1788-1857)

The picture has something of this: landscape, water, river, mountain, rock, outdoors, waterfall, tree, sky, fog, scenic, sunset, valley, nature, daylight, fall, snow, lake.
Perhaps it’s a painting of a mountain scene with a river in the foreground and a man on a raft in the middle of the river with a mountain in the background.
