I am curious to know if anybody understands how these mysterious crop circles formed in the dense boreal forest of Ontario, Canada?
Even if they also occur around the world (Quebec, the Yukon, and even as far afield as Russia and Australia), the highest concentration of forest rings is found in Northern Ontario (above 8’000 in overall). They range range from 30 metres to over 2 kilometres in diameter.
What’s the phenomenon behind?
The cause of this phenomenon remains unknown. Hyphotheses range from trees liying over methane deposits and mineral deposits to tree-killing fungus and multiple meteorite impacts.
New insights
It is now believed that these strange Canadian crop circles are triggered by large, naturally occurring electrochemical cells. In other words, the negative charge from the ‘batteries’ radiates outwards and where it meets positively charged oxygen in the soil the interaction of the opposite charges creates acidic conditions. This then eats away at the carbonate soil covering the region, resulting in a circular depression around the natural battery and stunted tree growth. Such conditions are often encountered above mineral and methane deposits.
The theory is that dead plankton and other organic matter left in the clay is now being consumed by large volumes of methane-producing bacteria.
Amazing, no?
