Getting here took a long time. First a flight to Seattle, then a connection to Fairbanks, followed by a coach to Coldfoot Camp and a final stage by minibus. It’s long after midnight and I’m shivering outside a snow-covered lodge in Wiseman, Alaska (population: 14), two hours north of the Arctic Circle, wrenching my tripod so the camera points straight upwards and trying like a fool to capture what essentially cannot be captured.
