This astounding one-of-a-kind photo of barrrenground caribou silhouetted by a veil of aurora borealis was taken by professional photographer David Olson during an August 2009 'Caribou, Musk-ox & Northern Lights' expedition to the lower Thelon River & Chesterfield Inlet region of Nunavut Canada. During early autumn ever year, caribou in full winter pelage lull from their migratory patterns and spread out to graze across the countryside in pairs & small groups to store essential winter fat and gather strength prepartory for the upcoming mating season in mid-October. Northern lights start becoming visible with their ghostly displays in mid-August, once darkness returns to the mainland Nunavut tundra.
