Star trails and aurora

The Brooks mountain range, which crosses Alaska's arctic region, is the farthest north mountain range in the United States. Just north of Atigun Pass--the highest road pass in the state-- is Atigun canyon, the location where this photo was taken. The northern lights were not that bright to the naked eye, but timed exposures are able to record more light and render more color. Circumstances prevented further experimentation with subsequent long exposures, (namely a semi-tractor accident nearby) which I wanted to do burn in longer star trails, but this one image turned out with a pleasing effect of motion and color.
