January 29th, 2015: Seasoned Firewood

The skeptical buyer says, how seasoned is it? How about 500 years?

Norwegian scientists have found “mummified” pine trees, dead for nearly 500 years yet without decomposition.

Norway’s wet climate seems perfect for encouraging organic matter to rot – particularly in Sogndal, located on Norway’s southwestern coastline, in one of the most humid, mild areas of the country. In fact, with an average of 1541 millimetres(61 inches) of rain yearly and relatively mild winters, Sogndal should be an environment where decomposition happens fast. Not so.

“We were gathering samples of dead trees to reconstruct summer temperatures in western Norway, when our dendrochronological dating showed the wood to be much older than expected”, says Terje Thun. “We were astounded to find fresh wood in trees that started to grow in the late 1200s and had died almost 500 years ago, which is much older than we originally expected. Somehow they have kept from decomposing for several centuries in this humid climate”, Thun says. “This is quite extraordinary - I would go as far as to call it sensational.”
