The headlight from a snowmobile driven by a Canadian Ranger illuminates a treeless landscape in a snowstorm during a patrol and caribou hunt several hours outside Gjoa Haven on King William Island, Nunavut, Canada. Navigating through extreme weather is a special skill which is essential to operating and surviving in the Polar region. Many Inuit can navigate using the lines of the snow to determine in which direction the wind is blowing which can help them determine direction.
