The other day we were hiking at Rumelange in the south of Luxembourg just at the border with France and the interesting part of this circular walk came at the end for us where there are caves and abandoned mines.
It was a hot day and it had rained a lot a few hours before and the air was very humid. We come across the abandoned Holleschbierg mine building and you could see clouds of smoke or dust blowing past the front of the building while there was virtually no wind. When we walked up, it became clear that the whole area was filled with a cold fog that was blowing away from the mountain. It was really puzzling until we walked a few meters further and spotted the mine opening disappearing like a tunnel into the mountain and from which a terrible cold wind blew. From then it was pretty easy to understand what was going on: simple condensation like we all learned about at school. 🙂
My photo clearly shows the fog at the bottom third of the shot.
I found a video on YouTube that shows the area pretty well; in short, we came walking down the path on the left of the building.
