Every winter the ice cover of Canadian Lake Abraham is speckled with surprising patterns of frozen air bubbles, which annually attract photographers from all over the world. This amazing lake was created during the construction of a dam on the River North Saskatchewan. According to Cultural Studies, lake was named after Silas Abraham, who lived in the area in the 19th century.
The famous bubbles on the lake are a natural phenomenon, whose origin is explained quite simply: at the bottom of the lake there are plants that produce methane. The methane bubbles rise up from the depth and freeze at different levels, creating entire chains.
