that she would be able to heat her coffee in the morning. The temperature sometimes dipped to forty or fifty degrees below zero, and she would have to spend a good half hour shivering in her coat and gloves before the tent truly began to warm up. She ate two or three multivitamins and a handful of dehydrated biscuits as she waited, and sometimes also a protein bar, and sometimes also a piece of chocolate, and she allowed a few chips of ice to melt on the surface of her tongue. Then she stripped to her long johns, tightened the drawstrings of the sleeping bag around her, and listened to the side wall of the tent going taut and slack and taut again, bellying in and out as it took the wind like a sail.
On the eighth day of the storm, she was traveling on a downhill slope when a spur of rock came rearing up out of the snow and filled her windshield. Her heart rose up in her chest. She swerved to avoid the rock, but it was too late.
She rammed into the spur at the rear corner and heard the solid crunch of something breaking. The sledge spun around twice and gradually drifted to a stop. She let go of the steering mechanism. Her skin was covered in sweat, and her stomach had tightened into a knot. The droning sound of the sledge slowly died away, and its runners settled into the snow. She checked herself for wounds. She seemed to be okay—no bleeding, no broken bones—but she wasn’t sure about the sledge. She climbed outside onto a half dozen chunks of rock and ice that had been knocked loose by the collision.
She made her way toward the back end of the vehicle, holding on to the upper rail with her gloves, the snow twisting around her in an obscuring shroud. She had heard stories about people who had become so disoriented in snowstorms that they had lost their sense of direction only a few feet from their front doors, people who went stumbling and weaving into the tempest with their arms stretched out in front of them like zombies. She knew better than to let go of the rail. She found the spot where the sledge had run into the spur. A long rent had been torn into the wood and metal, exposing the inside of the storage hutch. Her duffel bag was wedged inside the hole, so that only a thin crack of space remained open to the air, bordered with a row of jagged wooden teeth. She could hear the wind passing through it with a whistling noise.
She sank to her knees, probing at the snow around the runners to make sure nothing had fallen out. She couldn’t feel anything—the bulge of the duffel bag seemed to have sealed the breach in the hutch. She risked a short walk uphill, heading directly toward the spur, but all she saw was a tapering strip of wood and a single, palm-sized lump of black rock. When she was satisfied that she wouldn’t find anything else, she staggered back downhill. She turned the sledge around and continued along the channel of the ice stream.
It would be more than a month before she discovered exactly what she had left behind on the slope and the full consequences of her accident became clear to her.

That night, after she sealed the hole in the sledge with a strip of plywood, she found herself replaying a certain incident from her childhood. It came to her while she was pitching the tent, whirling and condensing in her memory like a tiny runaway planet, so that by the time she fastened the door it had returned to her in all its particulars. The incident was an inconsequential one—of no importance whatsoever, really. But then most of the things she remembered, most of the things anybody remembered, were of no natural importance—were they?—and that never stopped them from rising into the light.
In her memory she was seven years old, and her mother had just taken her out of school for a dentist’s appointment. Only that morning, her mother had said, “Now don’t let me forget, we have to get you to the dentist by two-thirty. What time do we have to get you to the dentist by?” and Laura had
