Abraham Lake in Alberta, Canada, is an artificial lake that hosts a spectacular phenomenon every winter—a vast collection of frozen bubbles beneath the surface, attracting many visitors. Friends who have immigrated to Canada may wish to visit and enjoy the sight on the weekend.
This phenomenon is caused by methane gas released by plants on the lake bed combined with the low temperatures at the surface. The methane gas continuously rises toward the surface, and when the temperature drops to a certain point, the lake begins to freeze, trapping the cavities formed by these bubbles. As the temperature continues to fall, these frozen bubbles accumulate, eventually resulting in the appearance we see today.
According to scientist Katey M. Walter Anthony from The University of Alaska Fairbanks, such scenery can be observed in many natural and artificial lakes around the world where similar natural phenomena occur.
Ross, a doctoral student at the University of Calgary, reminds visitors to be mindful of their safety and avoid falling. When she was taking the photo below, she attached crampons to her shoes to prevent being blown away by the strong winds.
