Extensive Landscape Peter De Wint (DeWint) (1784-1849)

The picture has something of this: water, smoke, steam, hot spring, landscape, geyser, thermal, lake, river, nature, outdoors, sky, dawn, tree, geothermal, sulfur, reflection, fog.
Perhaps it’s a painting of a landscape with a group of people in the foreground and a body of water in the background with a castle in the distance.
