Just look at this. In Antarctica’s Taylor Glacier, an oxygen-poor salty lake sits under 1,300 feet of ice, where the brine-like water occasionally gushes forth to flow down the glacier slope. The iron-rich water quickly oxidises upon meeting air to turn deep red — making the glacier look like it got stabbed or something. Apparently, when it was first discovered in 1911 by an expedition team, the redness was thought to be caused by algae growth. Super cool.
