These stunning frozen methane bubbles were captured at Abraham Lake

Alberta has many breathtaking bodies of waterframed by Rocky Mountain vistas, and some are made even more striking when temperatures sink below zero thanks to a phenomenon fizzing beneath the surface.

Largewhite bubblesare created in lakes and ponds when water-dwelling bacteriafeedon decaying organic matter and expelmethane gas. When the water freezes, the bubbles are suspended in the ice.

The bubbles areso prominent under the frozen surface of Alberta's artificially created Abraham Lakealong the David Thompson Highway southwest of Nordegg they lure visitors outdoors duringwintry months.

These shots were snapped by thosewilling to brave the coldto capture the seasonal effect.

And the images below were shot in previous winters, but are so stunning they still deserve a shout-out.

If you can't make it out to Lake Abraham, you can see methane bubbles in other bodies of water around the province when the conditions are right. Locations include:

• Barrier Lake, which is west of Calgaryin Kananaskis.To get there,take a turn south on Highway 40 from the Trans-Canada Highway.
• Banff National Park's Lake Minnewanka, locatednortheast of the Banff townsite.
• Spray Lakes, which is a short drive west of Calgary and just south of Canmore,
