@vegas.to.go: 🇨🇦 Alberta, Canada The picturesque Canadian Abraham Lake is a man-made object created during the construction of a dam. This lake is a favorite spot for photographers because its ice cover is dotted with patterns of frozen air bubbles. The reason for the natural phenomenon is simple: methane bubbles produced by plants rise from the bottom of the lake. They freeze at different depths, which creates such an extraordinary visual effect.
