Reflections Sun Pillar
I’ve seen them below the sun many times as well but not usually in a lake. They form on ice crystals in the atmosphere of course . A combination of many many reflections off the large flat face of horizontally falling like parachutes hexagonal plate ice crystals. The effect is very similar to any slightly tilted horizontal surface. For instance, water reflect a light source (usually the sun) and spread it out vertically. This one is pretty big. This is close to a 24mm image which is about twice the angle of your normal vision.
The Physics explains it of course but the bigger they are, the rarer they are. The maximum extent of the pillar is about twice the maximum tilt of the plate crystals. Big oriented plates of ice at a high angle are required for this to occur. The crystals, flat 6 sided plates all. These fall the same way due to atmospheric resistance and their shape. Calm falling air is necessary. The high tilt is unusual. I’ve read that a pillar 5-10 degrees pillar is not unusual. This is silly tall. I bet this is 40 degrees tall if not 45 degrees. This is a very big image wide and high. (I’d have to look at the meta data and do the math. It certainly seemed big to me at the time (click click click etc ).
I arrived at this remote location about 5 minutes too late to get the sun on the lake. Mapped in my head now… 👀📸.
