Arctic Grayling (Thymallus arctus) caught in the Nakolikuruk River near an orange tributary, Noatak National Preserve, Alaska
Arctic Grayling (Thymallus arctus) caught in the Nakolikuruk River near an orange tributary, Noatak National Preserve, AlaskaOrange streams are increasingly common in the Brooks Range of northern Alaska. The orange stream color reflects oxidized iron, but also often indicates elevated heavy metal concentrations. Our ongoing study aims to document these occurrences and the timing of their onset.
