At the foot of the Rocky Mountains in Canada, the manmade Abraham Lake captures a cool natural phenomenon every time it freezes over. High amounts of methane in the lake produce lots of air bubbles in the water, and when the lake freezes, the bubbles get trapped just beneath the surface. On the one hand, I'd feel much safer around these bubbles than a bubbling volcano, but I'd choose a different place to go ice skating. Winter seems to be a good time for Mother Nature's decorative touch, as these arctic frost flowers also need the freezing temperatures to bloom.
