Just read a article in the Jan/Feb Backwoodsman where a chimney developed a flue ice jam at -45 deg F by burning wet wood. Seems on New Years day or so kids reported seeing smoke coming from between the chimney stones and during cleaning apparently ice was found.

The power of cold, kind of seems plausible.

Anyone ever see this?

Last winter in Great Britain they had a lot of condensing boiler stacks freezing up because they were piped improperly. -45* is pretty cold.
Nothing is impossible for people who don't have to do it themselves.

I have seen chimney caps iced up at -20 from condensing flue gasses. Burning wet wood can plug the chimney in very mild weather...at -45 I bet it doesn't take long.
