On the morning of 6 May 2026, Anna Davenport was at the Jenny Lake ranger station at 04:30, drinking coffee from a paper cup, looking at the contents of her pack on the floor of the cabin in the order she would use them.
She is thirty-one and in her fifth season as a guide for Exum Mountain Guides, the oldest continuously operating guide service in the United States, founded by Glenn Exum in 1931 on the south side of the Lower Saddle of the Grand Teton. She is also the daughter of a former Exum guide named Wendell Davenport, who worked for the company from 1981 to 2007.
Her father, who is now seventy-three, lives in Driggs, Idaho, an hour's drive west of Jenny Lake. He had not been on the Grand for nineteen years until the previous summer, when his daughter took him up the Owen-Spalding route on a windless day in late July. He sat on the summit for ten minutes and did not speak. He shook his daughter's hand at the top of the rappels and they walked down to the Lower Saddle in silence.
The Tetons are, by the measure of any guide who has worked in the Alps or the Karakoram, a small range. The Grand Teton, the highest peak, tops out at 4,199 metres. The classic routes, by the standards of European alpinism, are short. None of this has any bearing on the difficulty of guiding them.
What makes the Tetons difficult is the weather. The range rises from the Wyoming high plains without intermediate elevation, and afternoon convection in the summer months produces lightning storms of a regularity and ferocity that have killed climbers in every decade since the first guided ascent in 1898.
Wendell Davenport's first season was 1981. He had come to the Tetons after two years at the University of Wyoming and one season working for a smaller outfit out of Bozeman. He started at Exum on the recommendation of Paul Petzoldt, who had co-founded the company with Glenn Exum and who, by then, was in his seventies and walking with a cane.
Petzoldt's advice to the young Davenport, given on the porch of the Jenny Lake guide hut over a cup of coffee in early June, was that the only skill the Tetons absolutely required was the skill of turning around. Davenport repeated this to his daughter when she joined Exum in 2021, on the same porch, with the same coffee, forty years later.
Anna Davenport's first season was a difficult one. She had grown up in Wilson, Wyoming, twenty minutes from the park, and had climbed the Grand for the first time at fourteen with her father. She had assumed, on starting at Exum, that she knew the range. She did not.
What she did not know, she later said, was the particular calibration required to guide a route she had soloed in three hours at the pace of a client who would need eight. The mountain at three hours and the mountain at eight hours are not the same mountain. The weather window is different. The patience required is different. The energy reserve required by the guide herself is different.
Her first season she turned around on the Grand four times. Two of those turnarounds were unambiguous, with weather visible from the Lower Saddle. Two were judgement calls, on days when the upper route would probably have been climbable but the client, in her assessment, would not have been able to descend it safely if the weather changed in the middle of the upper traverse.
Of those two judgement-call turnarounds, one was disputed by the client at the bottom and the other was thanked for. Davenport does not remember which client thanked her. She remembers, in detail, the one who did not.
The Exum guide system is organised, in the summer, around a base camp at the Lower Saddle of the Grand at 3,536 metres. The camp consists of a small wooden hut, several tent platforms, a propane stove, and a stack of foam pads in cardboard boxes. Clients arrive at the saddle in the early evening, sleep four to six hours, and start for the summit between 03:00 and 04:00 the following morning.
The senior guide on shift sleeps in the hut. Junior guides sleep in tents on the platforms. The senior guide is responsible, in the night, for monitoring the weather and for the decision, made by 03:00, of whether the day's parties will go up or down.
In 2026 the senior guide rotation included, for one ten-day shift in late June, Anna Davenport. She was the second-youngest guide ever to hold the senior shift, after a man named Renny Jackson who had taken it in 1976 at the age of twenty-eight. Davenport, when told this, said only that Jackson had been a better climber than she was.
Her father, asked the same question in his living room in Driggs, said that the senior shift was less about climbing than about a certain stillness of judgement at three in the morning, when the wind was rising and three guided parties were waking up and looking at her to decide.
He said that he had held the senior shift for the first time in 1985 at the age of thirty-three, and that the first morning he had been so worried about being wrong that he had not slept the four hours allotted to him. He had stood on the porch of the hut from midnight onward, watching the sky to the southwest.
The wind, on that 1985 morning, had risen at 02:40. He had woken the junior guides at 02:45 and told them to wake their clients and prepare to descend. By 04:30 all eighteen people who had been camped at the saddle were back below the technical terrain. By 06:30 the upper Grand was in cloud and the wind on the summit ridge, by later report, was at fifty knots.
Davenport had been right that morning, but he had been right in the way that, he said later, made him understand he could not stay in the trade for thirty years if every senior shift cost him a night of standing on a porch. He learned, the following summer, to sleep.
His daughter, in her first senior shift in 2026, slept for three of the allotted four hours and woke twice in the night to check the sky. She did not stand on the porch. She did, on her second night, write a single sentence in the senior guide's logbook, which is kept on a shelf above the propane stove. The sentence read: "Wind steady SW 8, cloud base above ridge, parties on schedule, going up."
The logbook on that shelf goes back, in some form or another, to 1959. Glenn Exum's own handwriting appears in it. Paul Petzoldt's does. Wendell Davenport's, in two long stretches in the 1980s and 1990s, does. Anna Davenport's, in the spring and summer of 2026, does.
The Grand Teton, on the morning her sentence was written, was climbed by all three of the parties on the saddle, in good weather, without incident. The clients descended to the valley by mid-afternoon. The senior guide, off shift the next morning, drove home to Wilson, slept for ten hours, and called her father from the kitchen the following day.
