Abraham Lake has become world famous, especially amongst photographers. The artificial lake, which lies in the foothills of the Canadian Rockies, is home to a rare phenomenon where bubbles get frozen right underneath its surface. They’re often referred to as ice bubbles or frozen bubbles.
What causes this to happen? As photographer Fikret Onal explains, “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.”
