Der Altauseer See mit dem Dachstein Friedrich Gauermann (1807-1862)

The picture has something of this: mountain, landscape, water, lake, valley, scenic, river, outdoors, nature, reflection, rock, sky, snow, hill, environment, tree, daylight, glacier.
Perhaps it’s a painting of a mountain scene with a river in the foreground and a mountain range in the background, with a few clouds in the sky.
