Quite a number of the thin wispy ones at the end particularly, are contrails. Ok, they're clouds too... nice collection though. Hope none are 'shopped...

Sorry to say but those are no contrails - they are cirrus clouds. Cirrus vertebratus, Cirrus fibratus - only the last picture by Norman J. has a crossed contrail in the background.
Thanks, Frank!

I would disagree - both photos on that line are all contrails. But of course, neither of us will know for sure...Originally Posted by GPS
I have seen many contrails grow to those formations in the right atmosphere, depending on the altitude they are formed in.
The picture's caption says - cloud... Anyway, the cirrus shows quite a long wavy structure, atypical for a contrail (compare with the two crossing contrails on the picture on the right). The fibres of this cirrus could develop from a contrail by the action of wind but then it would be difficult to create both the fibrus and the wavy structure. It seems that the cirrus on the left shows slight iridescence, typical of cirrus crystals. In a contrail made with ice crystals, these sublime quite quickly - this would contradict the long fibres than needs time to develop.
Thanks frank, I've been waiting 20 years to be at Mt Ranier when a lennie was there. I did get some at Mt St Helens though.
