Aurora Borealis Koyukuk River Fog, Alaska #2075

Description

Aurora Borealis Koyukuk River Fog, Alaska. On a cold September night, a slow fog builds over the Middle Fork Koyukuk River and is illuminated by the aurora borealis arcing above the Brooks Range. The Koyukuk reflects the colors of the aurora despite the flowing water. The northern lights persisted until dawn but soon after this photograph was made, the fog enveloped the river bottom, and a sharp frost coated the ground. The green aurora is characteristic of oxygen in the atmosphere, with occasional hints of purple, blue or pink caused by nitrogen. Sometimes a scarlet red color occurs and is caused by very high-altitude oxygen interacting with solar particles, Green is the typical color but magnificent nonetheless.
