It sure was not from steam. To make steam, water has to be heated to
a minimum of 212F at sea level. Steam is invisible, a vapor. When we
"see" steam, it is really vapor mixed with the condensate.

Half right. No steam in the river. Have you ever seen a river boil?


Water vapor is formed by evaporation or boiling. Water vapor though,
is not steam. Water vapor can condense on the walls when you shower,
it can condense over a river, make clouds in the sky.

Sublimation can also form water vapor. Much of the snow in Alaska is
sublimated rather than melted.
