OK, I'll go first.  Even though the distortion is considered to be "heat waves" caused by convection currents, it's not about the degree of heat. It's actually the temperature differential between two surfaces that causes the convection.  In this case, the air temperature was below freezing while the water was above freezing.  You can't see the effect close up but the telephoto magnification compresses the effect and makes it visible.

While I hadn't thought about the distorted horizon that is often seen over water, I agree that this fits the topic.  The "stretched" base of the mountain looks great, Gary, especially in the larger version.  Nice catch.
