In the village of Itilleq, beside a skyblue house, I found the head of a musk ox from a recent hunt. It was compelling on its own, but I wanted people in the picture. So I waited, worrying about the other photos I was missing. Then I remembered what Richardson said once when I asked him how long he'd wait: "I'm pretty impatient. If something isn't happening in eight or nine hours, then I'm gone."
