Ever wondered what frozen bubbles looked like? One Canadian photographer managed to get these shots – now going viral – of frozen bubbles under a lake in Alberta.
Photographer Paul Zizka captured shots of these bubbles in impressive detail during a trip to Lake Minnewanka in Banff.
News agency CBC said the bubbles are composed of methane gas, a byproduct of matter decaying below the lake. If temperatures plunge, the gas freezes, forming the bubbles.
“The trapped methane covers a huge portion of the lake in that area. The bubbles come in a variety of shapes and sizes, and some appear to be trapped in dozens of different layers of ice as they migrate upward – amazing sight,” Zizka wrote on his Facebook page.
He added that these were the “finest, most extensive methane bubbles I’ve ever seen at the far end of the lake.”
