STRANGE PLACES
BLOOD
FALLS
Antarctica's Mysterious Red Waterfall
A breathtaking natural phenomenon in Antarctica, where red-blood
water flows from a glacier – creating a striking and otherworldly
sight in the Earth’s coldest place.
QUICK FACTS
Location:
Taylor Glacier, Antarctica
Discovered:
1911 (by Thomas Griffith Taylor)
Colour:
Red (iron-rich water)
Source:
Subglacial lake (below glacier)
Type:
Natural phenomenon
BACKGROUND
Blood Falls is a striking red waterfall located in the McMurdo Dry Valleys of Antarctica, near the edge of Taylor Glacier. It was first discovered in 1911 by Thomas Griffith Taylor who noticed the unusual red stream flowing from the ice. For many years, the reason behind its red colour remained a mystery until scientists conducted detailed research in the 1960s and later.
SCIENTIFIC DISCOVEREY TIMELINE
1911 - First
Discovery
Thomas Griffith Taylor an Australain geologist, observes a red waterfall flowing from Taylor Glacier in Antarctica.
1960 - Initial
Scientific Research
Scientists begin studying the phenomenon and collecting samples of the red water to understand its source.
1970s - 1990s -
Deeper Investigation
Researchers reveal that the red water is rich in iron and other minerals, and comes from a subglacial lake beneath the glacier.
2000s - Present - Advanced Studies
Modern research using advanced technology has confirmed that the water is a natural, iron-rich, salty brine and scientists continue to study its unique chemistry.
SCIENTIFIC EXPLANATION
Blood Falls is created by iron-rich , salty water (brine) that flows from beneath Taylor Glacier. This water comes from a subglacial lake , which has been isolated from the surface for thousand of years. When this water comes out and is exposed to oxygen, the iron in it reacts and creates a rusty red colour, making the waterfall look like flowing blood.
KEY EVIDENCE
- Ice and rock samples collected form the area show high levels of iron and other minerals in the red water.
- Chemical analysis confirms the presence of iron-rich, salty water emerging from beneath the glacier.
- Studies have identified a subglacial lake under Taylor Glacier, which stores this salty water for thousand of years.
- Laboratory research shows the red colour is caused by iron in the water reacting with oxygen when it comes into contact with the air.
CURRENT STATUS
Blood Falls remains an active area of scientific research. Scientists are still studying the source, chemistry and microbial life in the subglacial lake, as well as the way iron-rich water reaches the surface. New studies continue to provide deeper insights into this unique Antarctic environment.
The exact mechanism that triggers the release of the red water to the surface is still not fully understood ?
How the subglacial lake and its iron-rich water system are connected and changing over time ?
Whether similar features exist in other parts of Antarctica and on other planets ?
