A crimson colored Sun pillar, captured near Hearst, Ontario just after sunset on June 10, 2011. Pillars take shape when sunlight is reflected from the bottom, or sometimes the top surface, of oriented, plate-shaped ice crystals. They need to be slightly tipped in the direction of the observer in order to cause the burst of vertical light. Since they’re reflection phenomena, they generally present but a single color.
