Blood Falls, a glacier in Antarctica, appears to be "bleeding" due to the presence of red iron oxide, a result of oxidized iron-rich saltwater flowing through it.

00:00Blood Falls, a glacier in Antarctica's Taylor Valley, is a fascinating natural wonder that
00:10appears to be bleeding due to its unique properties.
00:14The glacier regularly pours out a red liquid, creating an eerie effect.
00:19This phenomenon is caused by the presence of red iron oxide, or hematite, which is a
00:25result of the oxidation of iron-rich salt water that flows through the glacier.
00:30The source of this salt water is a trapped lake that existed about 5 million years ago,
00:35which was sealed under the glacier as it moved.
00:38As pressure builds up, the red liquid is released through a fissure in the glacier, creating
00:43the illusion of bleeding ice.
00:46Scientists study blood falls to gain insights into Antarctica's geological history and
00:52the unique ecosystem that exists beneath the glacier.
