“It’s a work trip.” She and Lowe had three sons, aged ten, seven, and three. But he’d felt obliged, both to his climbing partners and to the North Face and NBC Sports, which were underwriting the expedition. She’d had premonitions and dreams about this trip and-uncharacteristically, because she’d been a climber, too, and a supporter of her husband’s exploits-had begged Lowe not to go. Through the static of the satellite connection, Anker confirmed that her husband was gone. Lowe’s wife, Jennifer, back in Bozeman, got the call from base camp twelve hours later. A third, Anker, who’d fled in another direction, got flattened and engulfed by the blast, but after the air cleared he found himself stumbling through an altered landscape, alive and alone. On Shishapangma, a massive avalanche entombed two climbers, Lowe and the cameraman David Bridges, under tons of frozen debris. Still, snow is water, and it aims downhill. He was game for anything yet prudent, in his way-more dervish than daredevil. At the time, he was considered by many to be the world’s preëminent alpinist, and, even in a pursuit where untimely death is almost routine, his came as a shock. Lowe died in 1999, at the age of forty, during an ascent of Shishapangma, in the Himalayas. Anker recognized that it would be cosmically stupid to kick off an avalanche on the way. The group was headed to Alex Lowe Peak to spread Alex Lowe’s ashes. It was basically a hike up a minor mountain formerly known as Peak 10031 (for its unremarkable altitude of 10,031 feet), which had been rechristened in 2005 in honor of the late climber and Bozeman idol Alex Lowe. There was nothing intrepid, really, about this particular outing. So far, Anker, at fifty-four, was an exception. It is often said that there are old climbers and there are bold climbers, but there are no old bold climbers. This was Conrad Anker, the famous American alpinist.

To minimize exposure to avalanches, he made sure that everyone ascended with caution, keeping to the ridgelines and bare patches, away from the loaded gullies. The man at the head of the group was spooked by the new snow. Before dawn on the fifth, a group set off from a parking lot in Hyalite Canyon, a popular outdoor playground, just outside town. During the first week of October, 2017, a foot or more of snow fell in the peaks south of Bozeman, Montana. It runs some people out of the high country but draws others in. In mountain towns, an early-autumn snowstorm is a nuisance and a lure.
