Frozen heavenly orbs
Something magical happens in Lake Abraham, Alberta come winter. Clusters of trapped methane gas bubbles freeze, creating a beautiful display of ethereal orbs, beneath the glassy surface.
“The methane bubbles of Abraham Lake originate from the decaying organic matter like plants and animals on the lake's bottom. As this organic material decomposes, methane gas is released as part of the natural process. Because methane has low solubility in water, the gas bubbles cannot escape into the atmosphere and instead become trapped when the lake surface freezes over in winter.”
