Amazing Ice bubble Lake, Abraham Lake

The bubbles are methane gas, which is released when plants and animals decompose in the lake. The plants on the lake bed release methane gas and methane gets frozen once coming close enough to much colder lake surface and they keep stacking up below once the weather gets colder and colder during [the] winter season.
