I know it was not steam for sure. I am 99.9% positive it is not smoke. There was one person with me who smokes. This was not a formal investigation, that being said, as a habit, I do not photograph while anyone is smoking, and having viewed these photos soon after returning home and thinking back to the time when I snapped it, I did not have any thoughts this was the case. But to be fully honest, to me, it looks more like smoke than mist photos I have seen. This is one reason I have posted this photo. Another is I have picked out two forms in the picture and was wondering if anyone else can make them out, or its just my eyes thinking I see somethng.
