Story summary
- Blood Falls periodically erupts crimson liquid from the Taylor Glacier in Antarctica.
- Blood Falls, discovered in 1911, has a reddish color from iron oxidizing after being trapped underground by bacteria.
- The liquid is a hypersaline brine formed about 2 million years ago, preventing freezing.
- New findings indicate pressure variations beneath the glacier drive the eruptions.
- The eruptions slow the glacier's movement, though warming effects remain uncertain.
