Why would a white caribou come down to Beaver River, where the woodland herd lives? Why would she leave the Arctic tundra, where the light blazes incandescent, to haunt these shadows? Why would any caribou leave her herd to walk, solitary, thousands of miles? The herd is comfort. The herd is a fabric you can’t cut or tear, passing over the land. If you could see the herd from the sky, if you were a falcon or a king eider, it would appear like softly floating gauze over the face of the snow, no more substantial than a cloud. “We are soft,” the herd whispers. “We have no top teeth. We do not tear flesh. We do not tear at any part of life. We are gentleness itself. Why would any of us break from the herd? Break, apart, separate, these are hard words. The only reason any of us would become one, and not part of the herd, is if she were lost.
