Strange Blue Light in the Sky

Before yesterday morning, I had never heard of crepuscular rays. when I was doing my normal morning photo walk, I noticed a very distinctive beam of blue light stretching from the western horizon up towards the sky. Being the geek that I am (I record a weekly nature themed podcast), I did a google search and found that they are called crepuscular rays. Crepuscular is latin for twilight. As a biologist, we refer to any animal that is most active at dawn and dusk as crepuscular.

Apparently, these beams of light represent the shadows of storms far beyond the horizon. They are visible from great distances away, almost always at dawn or dusk, hence their name, crepuscular rays. While they appear as a converging beam, they are, in fact, parallel. Anyway, I thought it was cool.
