caption_attribution_description: English: Bubbles on frozen Abraham Lake
context_page_description: Abraham Lake, also known as Lake Abraham, is an artificial lake and Alberta's largest reservoir. It is located in the "Kootenay Plains area of the Canadian Rockies' front range", on the North Saskatchewan River in western Alberta, Canada.
context_section_description: Trapped methane causes frozen bubbles to form under the ice on the lake's surface. This phenomenon results when decaying plants on the lake bed release methane gas, which creates bubbles that become trapped within the ice, in suspended animation, just below the surface as the lake begins to freeze.  The visual effects formed by the resulting stacks of bubbles, frozen while rising toward the surface, combined with the clear blue water, have made Abraham Lake a popular destination for photographers and nature observers.
