There is a 1978 watercolor postcard by Alan Gussow entitled "Well-Rotted Manure, Steaming." His wife explains in her book This Organic Life how the blue-green steam on the artwork was not intended to represent the metabolic steam produced by the compost as it is being broken down by organisms, but the water vapor that sometimes rises as the sun burns off the morning dew. (People were pointing out that well rotted manure doesn't steam.)
Well-Rotted Manure, Steaming by Alan Gussow
Last week I witnessed the phenomenon myself on my garden compost pile. We had a cold morning with frost, and the sun was quickly warming surfaces. Dark surfaces, especially, were billowing with steam. I couldn't resist taking a picture.
It's nice, I think, to see the artistry in ordinary things.
