Unusual vapor trail over Colorado mountains appeared in altered photo.

Dear Sir, While traveling from Copper Mountain Ski area to Denver, on interstate 70, I was taking pictures from the car window. In one of the photos that I later altered with photoshop elements a vapor trail appeared.  My first thought was that I inadvertently created it with photoshop, but I am not sure so I am submitting the photos for an expert opinion.
The vapor trail does not appear to be that of a commercial aircraft since it has many sudden direction changes and the dissapation rate is not that of a commercial aircraft.  The trail also seems to go in and out of different altitude clouds.
I am submitting the original digital photo and the altered photo in hopes that you can give me a simple explanation of this anamoly.  If you need more information feel free to contact me in whatever way you deem appropriate but I would, very much, like to have an explanation from someone more experienced with this matter.
