Niagara Falls from the American Side Frederic Edwin Church (1826-1900)

The picture has something of this: water, waterfall, volcano, mist, fog, landscape, eruption, hot spring, smoke, steam, rainbow, H2O, outdoors, river, fall, winter, motion, geology.
Perhaps it’s a painting of a waterfall in the middle of a body of water with a rainbow in the middle of the water.
