Tributary of Kugururok River, Noatak National Park and Preserve, Alaska

Detailed Description
Tributary of Kugururok River located in Noatak National Park and Preserve, Alaska with orange water. Recent observations from Arctic Alaska indicate that waters draining permafrost landscapes may be susceptible to iron and carbon mobilization following thaw. One consequence of these altered iron-cycling processes is the abrupt change in color (orange) of stream and river reaches, reflecting a dramatic shift in water quality.
