Forest of Fontainebleau, c. 1830, Detalj 3, NG Washing Jean-Baptiste-Camille Corot (1796-1875)

The picture has something of this: water, nature, landscape, river, outdoors, tree, rock, environment, park, light, daylight, smoke, scenic, lake, fall, underwater.
Perhaps it’s a painting of a man sitting on a rock with a horse in the foreground and a man standing on a cliff.
