Forty minutes later, bundled under six layers of clothing, Andy inked his name on the whiteboard hanging next to the cold lock and stepped through the heavily insulated door. The difference in temperature between the interior of the station and the small anteroom that lead to the exit was a whopping ninety degrees. Gangle’s breath turned into an opaque cloud as dense as any London fog, and each inhalation stabbed deep into his lungs. He waited for a few minutes to adjust his clothing and fit his goggles over his eyes. While the Antarctic Peninsula was relatively warm compared to the interior of the continent, any exposed skin would still get frostbitten in moments.

All the clothing in the world still wasn’t enough to defeat the cold, not in the long term. Heat loss was inevitable, and, with the wind, inexorable. It started at the extremities—nose, fingertips, and toes—then spread inward as the body shut itself down to conserve its core temperature. It wasn’t a matter of willpower, facing these extremes in temperature. One couldn’t just bull through the pain. Antarctica was as deadly to human life as the hard vacuum of outer space.

With cumbersome overmittens covering his gloves, Andy needed both hands to turn the doorknob. The real cold hit him hard. It would take several seconds for the air trapped in his clothing to warm against such a thermal onslaught. He shivered for a moment, then rounded the corner that protected the exit from the wind. He clutched the handrail as he made his way down the stairs to the rocky ground. There wasn’t much wind today—ten knots, maybe—and for that he was grateful.

He grabbed up a five-foot length of metal conduit pipe as thick around as a fifty-cent piece and headed out.

The sun was a pale promise that circled the horizon but wouldn’t emerge above it for another week, but it gave enough light for Andy to see without using his headlamp. His moon boots were inflexible and made walking difficult, and the terrain didn’t help much. This part of the Antarctic Peninsula was volcanic, and not enough time had passed since the last eruption for the elements to have eroded the rock to a glassy smoothness like he’d seen pictures of during orientation training.

Another thing he’d learned during his orientation was to never sweat outside. Ironically, that was the ticket to fast-onset hypothermia because the body shed heat so much faster when exertion opened the skin’s pores. Therefore, it took Andy twenty minutes to reach his search area. If Greg Lamont was right and this was his last day to be outside until extraction, Gangle felt this might be the best spot. It was closer to the beach from where he’d made his discovery but in line with a low range of hills that afforded protection. For the next two hours, he walked back and forth, his goggled eyes sweeping the ground. Whenever anything promising appeared, he would use the steel pipe to probe the ice and snow or lever rocks out of the way. It was mindless work, for which he was particularly well suited, and the time seemed to slip away. His only distraction came when he felt the need to run in a circle for a few minutes. He managed to stop himself before he worked up a sweat, but his breath had frozen to the three scarves he had wrapped around his nose and mouth. He pulled them off to retie them so the icy snot was around the back of his head.
