Abraham Lake, Alberta, Canada
To the uninitiated this looks like a lake filled with the kind of surreal jellyfish you only see in animated movies. But what you’re actually seeing is frozen gas bubbles – Alberta’s Lake Abraham has a high density of dead organic materials and the result is that in winter bubbles of frozen methane form to create this enchanting view. The best time to go is December to March when the lake is most likely to be frozen. Warning: do not light a match.
