Stelvio Road by Lago di Como Sanford Robinson Gifford (1823-1880)

The picture has something of this: cave, subway system, tunnel, people, geology, rock, stalactite, light, exploration, limestone, landscape, grotto, canyon, sandstone, outdoors, water.
Perhaps it’s a painting of a man standing at the end of a tunnel with a view of mountains and a body of water on the other side of the road.
