Cow manure decomposition

Cow manure covered in snow. The manure decomposes from bacteria, and its temperature raises. Hence, the recently fallen snow (10-15 cm in the previous 2-3 days) has melted and due to the low air temperatures (the photo was taken at around 18:00 with temperatures around zero deg Celcius) smoke cloud is visible. The photo was taken at the village of Volakas, some 35 km from Drama, NE Greece.
