Contrail

I took this photo using the pano function on the phone - sideways - and while it doesn't look exactly like it looked to our eyes, it's pretty darned close. The sky was full of unusual cirrus clouds and a lot of contrails. This one was dissipating in a most interesting manner. The little pyramid of a mountain at the bottom of the frame is Buck Mountain - or as I prefer to call it - Mount Buck. 'Tis but a wee mountain.
