Monksville Reservoir

I have to drive over Monksville Reservoir everyday on my way to work. With the recent spate of freezing temps, the heat vapors have been dancing on the surface; glimmering in the sun. It has been this way all week. (Remember it has been in the 20s on the mountain.) Yesterday I decided to pull over and try to capture the rising mist.
Here's another one.

Sorta cool, huh. I wonder if this phenomenon has a name? Anyone know?
