The painting depicts the depths of Black Pool, a large hot water spring in the West Thumb area of Yellowstone National Park. The yellow and orange surface on the lower right is cool enough to support thermophiles. The blue depths of the pool are an indication that the temperature is too hot even for thermophiles to survive.
