Mackerel Sky

I love mackerel skies. The patterns that form in the clouds are so fascinating, and they usually change very quickly. Then there's also the possibility of a gorgeous sunset with tons of color. This one didn't go into much color, but the play of light and shadow was awesome.

More than you ever wanted to know about mackerel skies.

A bit of music trivia: the band Cowboy Junkies mentions a mackerel sky in their "Anniversay Song."
