Sky Art - "Jet Stream" Cirrus Clouds

I'd actually set out on Friday afternoon to capture what I thought was going to be a nice sunset. As it happened, however, the sunset itself was a bit of a let down ... :o|
But all was not lost ... On the way to my preferred vantage point, I noticed the high clouds looking very uniform ... So I pulled my van over to the side of the road and took a couple of quick photos ... :o)
This is a natural phenomenon generated by the jet stream and the high "cirrus" clouds, but I must confess that it was a new one on me ... :o)
