Volcanic illusion

A smoking volcano Who can figure out how this happened?

Wow very cool. Was it a plane disappearing behind the mountains or coming up from behind it?

@witchyjacq You guessed it (now am stamping foot like Rumplestiltskin) yes it was a jet trail heading behind the mountain - I had followed the jet trail most of the way until the home straight at Havelock and there it was looking for all the world like a smoking volcano!
