National Parks Traveler Podcast | Alaska's Stained Rivers

Author: Kurt Repanshek June 30, 2024 Duration: 49:41

In the remote wilderness of the Brooks Mountain Range in Alaska, where untamed rivers wind through vast expanses of tundra and towering mountains, a peculiar and alarming phenomenon is taking place. Since 2017 at least 75 pristine waterways, which once shimmered with crystalline clarity, have taken on a haunting hue of orange and now contain very concerning toxic metals and minerals.

As speculation gives way to investigation, a team of researchers has been looking at the region's rapidly thawing permafrost—a phenomenon they suspect may hold the key to unraveling this disturbing transformation. 

This week the Traveler's Lynn Riddick talks with key scientists with the National Park Service and the University of California Davis on their new study that investigates these altered headwater tributaries, including ones in five national parks and a number of other protected areas. Among their findings are impacts to aquatic life, ecosystems, drinking water and the locals who rely on fishing for subsistence.


There's a world of stories waiting beyond the park entrance sign, and the National Parks Traveler Podcast is your audio guide to them. Led by Kurt Repanshek, this series goes deeper than trail maps and visitor statistics. It connects the natural wonder you experience firsthand with the crucial, often unseen work happening behind the scenes-the science informing conservation, the cultural histories embedded in the landscape, and the policy decisions that will shape these places for future generations. As the audio companion to the editorially independent nonprofit media organization, this podcast delivers a thoughtful blend of on-the-ground reports, interviews with researchers and park staff, and nuanced discussions about the challenges and triumphs in managing protected areas. You'll hear the sounds of the parks and the voices of the people dedicated to them. Each episode is an invitation to better understand the complex tapestry of ecology, history, and society that makes every national park far more than a scenic destination. Tune in for a regular dose of insight that will deepen your appreciation and perhaps even shape your next journey into America's most treasured public lands.
