The Sandling at Altaussee Ferdinand Georg Waldmüller (1793-1865)

The picture has something of this: mountain, landscape, nature, outdoors, tree, water, sky, valley, hill, rock, sunset, dawn, river, wood, fog, volcano, scenic, grass.
Perhaps it’s a painting of a mountain scene with a river in the foreground and trees on the other side of the painting, with a stream.
