Kate Harris, an adventurer and author of Lands of Lost Borders, about her solo bicycle journey along the ancient Silk Road, was one of the women on that Workman-inspired trip. She’d met Criscitiello at MIT in 2008, and they’d become fast friends. “I hung on for dear life,” says Harris of the experience. Harris says Criscitiello was in charge, her athleticism dominant. But it was her way of com- bining her disparate skills into a cohesive whole — linking the mountaineering with research that aims to preserve ice and cold in the places she loves to experience — that stuck for Harris. “The best descriptor of Alison is ‘explorer,’” says Harris. “She truly updates the term, makes it modern and fresh.”

In May, Criscitiello will yet again attempt to add to her list of firsts. After the coronavirus pandemic scuppered her 2020 plan for the Mount Logan Ice Expedition, a project in the Yukon sponsored in part by The Royal Canadian Geographical Society, Criscitiello has reimagined it. Originally, she was to lead a four-person team of male scientists to climb Canada’s tallest peak, to survey sites for, then later drill, an ancient ice core and, secondarily, to re-measure the mountain’s height, believed to be 5,959 metres.

A friend of Criscitiello’s, and fellow climber, Zac Robinson, an associate professor of kinesiology, sport and recreation at the University of Alberta, says Criscitiello’s preparation for such expeditions, in addition to all her other work, is impressive. “The fact that she does all of these things in addition to spending daily bike sessions in a hypoxia chamber, running multiple marathons in a week, dashing up peaks on the weekend and being a young parent makes her superhuman, as far as I’m concerned,” says Robinson.

In 2021, because of pandemic travel restrictions, Criscitiello has had to chart a new course for the Logan expedition in typical push-the-limits style. In May, it’ll now just be her and a small team of Canadians, including her main climbing partner, who summited with her on Mount Logan, instead of the larger group.

Given that Criscitiello has experienced first-hand the other side of the fragile barrier between adventure and tragedy, as well as extreme dangers presented by this mountain in part- icular, it’s a challenge that’s clearly sitting with her.

Says Criscitiello: “I’m definitely scared of Logan.”

About 20 years ago, in a small yurt 29 kilometres from the trail-head for Washington’s Hoh River valley, Criscitiello felt something pull at her. It was there, at altitudes as high as 2,432 metres, along a hiking path that started in rainforest, evolved into alpine and ended at the powder-blue ice of some of the nearly 200 glaciers in Olympic National Park, that she noticed it. Somehow, she was being pulled toward ice.

From her yurt, which doubled as a station for her job as a ranger with the National Park Service, Criscitiello looked onto Blue Glacier. She was 20 and had come to this place as soon as she finished high school, looking for a challenge. But for someone already so capable, it was the ice, and the extreme altitude and cold that sustained it, that inspired something new within her.

“I was surrounded by glaciers,” she says. “The whole landscape and everything I could see from where I lived was shaped by ice. It was such a dynamic and complex landscape. Dangerous. You know, you think people shouldn’t be here. It’s just so powerful.”

She was hooked. It was her first experience being what she calls “two feet in.” Beyond comfort. She often worked alone for 10-day stints in the park, save a nightly, 20-second-long radio check-in. The days were just her and the ice, contemplating the rare factors that came together to allow it to be, how she needed all her wits to survive.

Several factors had merged to put her here in the first place. Her passion for outdoor adventure started in childhood, on multi-day trips to the mountains in New Hampshire with her identical-twin sister, Ra. The trips were escapes from the pair’s easy lives in the suburbs of Boston. But her parents had played a role, too. They were overachievers — her mom taught English and was completing her PhD when she had Criscitiello and her sister, while her father was a family physician. Critically, they saw their twin daughters as independent and interdependent and let them pursue outdoor adventures without supervision at an age many parents would not have.

First came overnight camping with family friends on an island in a small lake; next came the 33-kilometre Presidential Traverse Trail in New Hampshire’s White Mountain National Forest. Criscitiello and Ra hiked it by themselves, camping for several nights. They were 12. In her twin, Criscitiello had “a born-in adventure partner.”

It was ice that hooked her and set her on a new path and eventually led to her working as a researcher on an icebreaker in Antarctica. She was now quite literally at sea level. The ice was abundantly there, as was the science. But the altitude wasn’t. Nor was her heart.

“It definitely didn’t click,” says Criscitiello. “I went from throwing myself physically into these places where I wanted to be, to alternately, in some ways, burning out. I just really wanted to study and understand the environment, and not just move through it.”

She took time to reset. She realized the connection between ice and altitude was the cold and ideally other women who shared her passions. She found a woman like her. Then it clicked. “It’s always important to see people doing what we want to do, and I didn’t see people doing what I wanted to do when I decided to get into this,” says Criscitiello, “until I found my PhD advisor at MIT.”

The path she’s been on since is to conduct remote, extreme polar science with women, whenever she can. “It feels different to me. There’s power to it.” Her research specialty is studying sea ice and its history hidden within ice cores, which in turn is a historical record of ancient climates. But beyond this, her passion is to explore what we do not know by finding new ice that adds to the record — by living on ice for months at a time in places such as Greenland, Antarctica, South America, the Arctic — and drilling into it to find its secrets.

That’s why the trip to Mount Logan has been on her mind for years. A meltdown of the ice core lab in 2017 (in which some of the cores from Logan were damaged) partially sparked it, of course, but so did the past. The original cores from the area stored in the lab were from 2002, harvested by a team that didn’t have the technology available today to find the oldest ice. The cores are “not necessarily from the right site,” says Criscitiello.

What she’s after, this time using newer ground-penetrating radar technology to locate it, is likely the oldest non-Arctic ice still in existence, something in the neighbourhood of 30,000 years old. It’s ice that has never melted and refrozen, and thus has locked in a part of history.

Its location on Mount Logan is vital. Most ice polar scientists like her deal with it at the North and South poles. This gives researchers a picture into changes in global climate. What ancient ice at Mount Logan offers, on the other hand, is a more localized archive of climate for the region.

“The record that exists on Logan might be able to tell us something, for example, about how El Niño has changed in the past and has impacted the Pacific Northwest and that region of Alaska and Yukon in ways that we just don’t know because we don’t have records from the right part of the Earth,” says Criscitiello.

To find it means climbing one of the highest, coldest, most remote peaks in the world. Two-feet-in sort of stuff.

Today, at 39, with a two-year old daughter, named Winter, Criscitiello says she’s changing. She once felt a pull only toward the ice, and the extreme places where it remains. Now there’s a force in her life that sounds a lot like balance.

“When I was younger, and a student in particular, and even through my post-doc, I think I would say that I spent about half the year in the field, and that field part of my year is really what kept me hanging on through all of the meticulous lab work and data analysis and paper writing,” she says. “But now I don’t know. It’s only been the last couple of years, but it’s shifted a little bit to both. When I’m in the field I have a pull to be here. And when I’m here I always have a pull to be on the ice.”

The losses she has experienced may play a role. In 2016, Criscitiello and her close friend, Anna Smith, flew to India to climb in the Miyar Valley. At 4,700 metres, Criscitiello wrote in her award- winning story about the trip in the fall 2017 issue of Alpinist magazine, she turned to see Smith slumped over and vomiting. Criscitiello helped Smith down to their advanced base camp, where she looked after her for the next three days. But on the fourth day she woke, opened Smith’s tent and discovered her lifeless body.

“Eventually, I did the single hardest thing I have done in my 35 years: I sent two messages — one to Anna’s mother and one to her partner — telling them. It took a long time to find the words,” wrote Criscitiello in 2017.
