A common question from #photographers at #BosqueDelApache National #Wildlife #Refuge is "where/how do I photograph the steam/fog/hot springs? The "steam/fog" seen forming about the #wetlands is not actually the result of liquid boiling to gas form (there are no hot spring here); but rather a process of condensation as #water vapor in the air directly above #lakes surfaces is cooled by the low temperatures of the surface water. The effect is usually most pronounced in #winter months following cold clear nights. Water just below the surface remains warmer so that vapor still forms above the lake; but the chilled surface causes the vapor to condense into a misty layer of "steam/fog."
