The pioneering Canadian freestyler, who helped get superpipe accepted into the Olympics, died Thursday after a Jan. 10 crash during a training run in Park City, Utah.
Burke, who lived near Whistler, in British Columbia, was 29.
"Sarah was the one who, in a very positive way, stood in the face of adversity and asked, 'Why not?'" said Peter Judge, the CEO of Canada's freestyle team. "What she would have wanted was for her teammates and others in her sport to stand up and also say, 'Why not?' To benefit from the significant opportunities available to them, being able to compete in the Olympics and the X Games. Those were the things she wanted and cherished and fought for."
A four-time Winter X Games champion, Burke crashed on the same halfpipe where snowboarder Kevin Pearce sustained a traumatic brain injury during a training accident on Dec. 31, 2009.
Tests revealed she sustained "irreversible damage to her brain due to lack of oxygen and blood after cardiac arrest," according to a statement released by her publicist, Nicole Wool, on behalf of the family.
She said Burke's organs and tissues were donated, as the skier had requested before the accident.
"The family expresses their heartfelt gratitude for the international outpouring of support they have received from all the people Sarah touched," the statement said.
Judge said the accident did not come on a risky trick, but rather, a simple 540-degree jump that Burke usually landed routinely.
"It was more the freak nature of how she landed," he said. "The angle of how she hit must have been exactly the right way, to create a very bizarre circumstance."
Burke will be remembered as much for the hardware she collected as the legacy she left for women in superpipe skiing, a sister sport to the more popular snowboarding brand that has turned Shaun White, Hannah Teter and others into stars.
Aware of the big role the Olympics played in pushing the Whites of the world from the fringes into the mainstream, Burke lobbied to add superpipe skiing to the Winter Games program, noting that no new infrastructure would be needed.
Her arguments won over Olympic officials, and the discipline will debut in two years in Russia, where Burke likely would have been a favorite for the gold medal.
She was, Judge said, as committed to mentoring up-and-coming competitors and giving clinics as performing at the top levels.
"She was a kind person who was easygoing and approachable," Judge said. "There was no pretense about her."
News of Burke's death spread quickly through the action-sports world, where the Winter X Games are set to start next week in Aspen, Colo., without one of their biggest and most-beloved stars.
"She's probably one of the nicest people I've known in my life, and that's about the only thing I have to say about it," said American superpipe skier Simon Dumont, a multiple X Games medalist.
Jeremy Forster, the program director for U.S. Freeskiing and U.S. Snowboarding, said freeskiers would remember Burke "first, as a friend, and then as a competitor who constantly inspired them to do greater things."
"She was a leader in her sport, and it's a huge loss for the freeskiing community," Forster said.
"I am eternally indebted to Sarah for what she has done for this sport," said American superpipe skier Jen Hudak. "Every turn I ever make will be for her."
A moment of silence for Burke was observed before Canada's women's soccer team played Haiti in an Olympic qualifying match in Vancouver on Thursday night.
Burke's death is sure to re-ignite the debate over safety on the halfpipe.
Pearce's injury — he has since recovered and is back to riding on snow — was a jarring reminder of the dangers posed to these athletes who often market themselves as devil-may-care thrillseekers but know they make their living in a far more serious, and dangerous, profession.
The sport's leaders defend the record, saying mandatory helmets and air bags used on the sides of pipes during practice and better pipe-building technology has made this a safer sport, even though the walls of the pipes have risen significantly over the past decade. They now stand at 22 feet high.
Some of the movement to the halfpipe decades ago came because racing down the mountain, the way they do in snowboardcross and skicross, was considered even more dangerous — the conditions more unpredictable and the athletes less concerned with each other's safety.
But there are few consistent, hard-and-fast guidelines when it comes to limiting the difficulty of the tricks in the halfpipe, and as the money and fame available in the sport grew, so did the tricks. In 2010, snowboarding pioneer Jake Burton told The Associated Press that much of this was self-policed by athletes who knew where to draw the line.
"If the sport got to the point where halfpipe riding became really dangerous, I think riders would do something about it," Burton said. "It wouldn't be cool anymore."
His opinion is shared by many.
"From a safety perspective, it's just very difficult to really understand if there was anything that could've been done any differently to make it any safer," Judge said.
In 2009, Burke broke a vertebra in her back after landing awkwardly while competing in slopestyle at the X Games. It was her lobbying that helped get the X Games to include women's slopestyle — where riders shoot down the mountain and over "features" including bumps and rails.
It wasn't her best event, but she felt compelled to compete because she pushed for it. She came to terms with her injury quickly.
"I've been doing this for long time, 11 years," she said in a 2010 interview. "I've been very lucky with the injuries I've had. It's part of the game. Everybody gets hurt. Looking back on it, I'd probably do the exact same thing again."
She returned a year after that injury and kept going at the highest level, trying the toughest tricks and winning the biggest prizes.
A native of Midland, Ontario, Burke won the ESPY in 2007 as female action sports athlete of the year.
In 2010, she married another freestyle skier, Rory Bushfield, and they were headliners in a documentary film project on the Ski Channel called "Winter."
In her interview with AP two years ago, Burke reflected on the niche she'd carved out in the action-sports world.
"I think we're all doing this, first off, because we love it and want to be the best," she said. "But I also think it would've been a great opportunity, huge for myself and for skiing and for everyone, if we could've gotten into the (Vancouver) Olympics. It's sad. I mean, I'm super lucky to be where I am, but that would've been pretty awesome."
A little more than a year later, with Burke's prodding, her sport was voted in for the next Winter Games.
