This up to 1000 years old snow has metamorphosed into highly pressurized  glacier ice that contains almost no air bubbles. Thus it absorbs the  visible light despite the scattered shortest blue fraction, giving it  its distinct deep blue waved appearance. This cavity in the glacier ice  formed as a result of a glacial mill, or moulin.
Rain and meltwater on  the glacier surface is channelled into streams that enter the glacier at  crevices. The waterfall melts a hole into the glacier while the ponded  water drains towards lower elevations by forming long ice caves with an  outlet at the terminus of the glacier. The fine grained sediments in the  water along with wind blown sediments cause the frozen meltwater stream  to appear in a muddy colour while the top of the cave exhibits the deep  blue colour.
Due to the fast movement of the glacier of about 1 m per  day over uneven terrain this ice cave cracked up at its end into a deep  vertical crevice, called cerrac. This causes the indirect daylight to  enter the ice cave from both ends resulting in homogeneous lighting of  the ice tunnel.

On my flight home last night, we flew over a thunderstorm with lots of lightning. My pictures look like crap, but this pic I found is a fair representation of what I saw for 10 minutes.

Sonic Boom meets Sun Dog

A sun dog is a prismatic bright spot in the sky caused by sun shining through ice crystals. ” And when you do a sonic boom in the middle of it, awesome stuff happens.
