Rivers Turn Bright Orange in Alaska
Some of Alaska’s scenic rivers and streams look downright apocalyptic this year because they turned a flagrant orange color — but it’s not due to local pollution, according to scientists at the National Oceanic and Atmospheric Administration (NOAA).
In actuality, the orange tinted water is rust, released as the frozen ground in Alaska thaws out due to unchecked greenhouse gasses driving global warming. And it’s leaking into the state’s waterways, according to NOAA’s annual report on the Arctic region, where it’s posing a danger to local wildlife, residents and commercial fisheries.
The day-glo rivers are also a bright orange flag that the Arctic is warming faster than the rest of the world. The massive defrosting is also anticipated to increase sea levels and screw up weather patterns, according to scientists who talked to NPR.
“When the Arctic thaws and warms, it’s having an impact on the global climate,” Matthew Druckenmiller, lead author of the report and senior scientist with the Boulder, Colorado-based National Snow and Ice Data Center, told the broadcaster.
The planet is already showing signs of distress from global warming, such as large-scale forest fires and extreme summer temperatures outside the Arctic, which Druckenmiller described as a giant fridge for the planet.
“The Arctic is warming several times faster than Earth as a whole, reshaping the northern landscapes, ecosystems, and livelihoods of Arctic peoples,” reads the NOAA report. “Also transforming are the roles the Arctic plays in the global climate, economic, and societal systems.”
Zooming back to Alaska, people started noticing the orange waterways in 2018, according to NPR.
“ We heard from people who live in the region — pilots who are often flying over, people in the national parks,” US Geological Survey research hydrologist Josh Koch told the broadcaster.
As temperatures heats up in the most remote parts of Alaska, permafrost — ground that usually stays continuously frozen — is melting, and that’s unlocking iron in the soil, which oxidizes from exposure to water and air, causing rivers and streams to turn orange. Surveys revealed that this contamination is far reaching, covering hundreds of miles of terrain in Alaska.
“It’s often not orange until it reaches the stream, and then all the iron and other metals can precipitate and create this iron staining,” Koch added.
It’s not clear if residents are being harmed from the polluted water, but local scientists are monitoring the situation, NPR reports.
The other problem with these rusty rivers is that they increase the acidity level in the water, according to the NOAA report, and this may harm fish like Dolly Varden char, whose juvenile offspring have experienced a sharp decrease in numbers most likely due to iron in its aquatic habitat. And that’s pretty bad for everybody in Alaska.
“The food chain is connected to the lives of people living in the Arctic,” Druckenmiller said.

Junior Jayden Miranda on Friday became the latest player from West Valley High School to be named Gatorade Alaska Boys Basketball Player of the Year.
“It feels good and it was definitely one of the goals that I had to check off my checklist,” he said. “I woke up, and I didn’t know. My coach told me, and it was just excitement in my heart. My heart was beating and I was just smiling.”
Miranda led the Wolfpack boys basketball team to a Mid Alaska Conference championship and the No. 1 seed at the 2026 ASAA 4A state tournament.
The 5-foot-11 guard also helped lead West Valley to a 22-4 record, and through 23 games, he averaged 14.7 points, 3.8 rebounds and 2.5 assists as well as shooting 51.8% from the floor and 39.7% from the perimeter.
“Miranda is a great kid on and off the court — gets good grades and never gets in trouble,” North Pole head coach Travis Church said in a statement. “Looking around 4A, I don’t see anyone who would measure up. He’s the best player on the best team in the state. It’s hard for me to imagine going with anyone else.”
Miranda is the second player from the program to receive the award. The first was two-time recipient Stewart Erhart, who was honored in back-to-back years from 2022-23.
The award acknowledges a student-athlete’s athletic achievement, and also recognizes outstanding academic excellence and exceptional character displayed on and off the court.
Miranda maintained a 3.36 GPA and volunteered locally with the Fairbanks Community Food Bank, donated time as a youth basketball coach and is a practiced artist who has also taken multiple cooking classes in high school.
He and the top-seeded Wolfpack fell short of advancing to the finals Friday after losing 59-52 to fifth-seeded South Anchorage.
