Situated north of the Cap Vert Peninsula in Senegal, northeast of Dakar, Lake Retba, or as the French refer to it Lac Rose, is pinker than any milkshake.

Retba has a high salt content, much like that of the Dead Sea, allowing people to float effortlessly in the massive pink water.

Frozen Bubbles Suspended Below Abraham Lake. 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. Often referred to as ice bubbles or frozen bubbles, the plants on the lake bed release methane gas and the methane gets frozen once coming close enough to much colder lake surface. They keep stacking up below once the weather gets colder and colder during the winter season.”
