Scientists recently visited 75 crystal clear waterways in Alaska that had all turned orange. By taking samples, they were able to find a reason why.

Some of Alaska's clear, icy blue waterways are turning a startling rust orange - so intense it's visible from Earth's orbit. "The stained rivers are so big we can see them from space," says University of California (UC) Davis environmental...

Dozens of rivers and streams in the US state of Alaska are turning rusty orange. Scientists believe that permafrost, or frozen land, is what is causing the hue change. They claim that when the environment warmed, minerals kept in permafrost were released into glistening, clean water. Researchers are also concerned, as this change could threaten fisheries and drinking water quality

Alaskas melting permafrost is dumping toxic metals into the states rivers, turning them bright orange and making the water highly acidic. The contaminated rivers are so vibrant they can be seen from space, and the problem is likely to get much worse in the future.

Thawing permafrost may be driving degradation

Dozens of Alaskas rivers and streams are turning orange. The staining could be the result of minerals exposed by thawing permafrost and climate change, finds a new study.

Environment News: Thawing permafrost in Alaska is turning clear waters rusty orange, impacting water quality and ecosystems. The process releases methane, carbon dioxid

Scientists believe that this could be down to melting permafrost, which releases metals into the water.

For the first time, scientists from across North America have formed a clear picture of Alaska's 'rusting' rivers and streams, tracking 75 areas in the remote Brooks Range that are flushed with the bizarre hue so bright it's even visible from space.

Melting permafrost has made 75 of Alaskas streams and 41 wetlands burn - blackening vegetation like wildfire, leaving fish suffocated and threatening local citizens
