The identities of six of the nine backcountry skiers killed in a deadly avalanche at Lake Tahoe’s Castle Peak have been revealed.

Kate Vitt, a former Sirius XM radio executive and mother of two from Marin County, was the first avalanche victim identified Thursday.

Sisters Caroline Sekar, 45, and Liz Clabaugh, 52, were also named as victims in the catastrophic event. They were on a trip with friends from Stanford University when they got caught in the snow slide.

Carrie Atkin, Kate Morse and Danielle Keatley were the three other victims.

Kate Vitt lived with her husband and two sons in Marin County and served as vice president at SiriusXM before leaving in 2025.

She graduated from Boston College and worked for Pandora and Anthropologie, according to her LinkedIn profile.

A neighbor of Vitt and her husband Geoff called the incident “heartbreaking.”

“She was just a lovely person and would light up the room,” Diane Gerold said. “Always very happy.”

Caroline, 45, lived in San Francisco with her husband and kids.

“Caroline spent her final days doing what she loved best, with the people who loved her most, in her favorite place,” her husband, Kiren Sekar, told the New York Times.

“She was with me, her children and our puppy, and then on one last adventure with her sister and close friends, who she now rests with.”

Kiren, who was with his wife for more than 20 years, described Caroline as “authentic and unabashedly unfiltered.” He said they taught their children to cherish adventure-centric activities like hiking, skiing and bicycling.

Liz Clabaugh, 52, was based in Idaho and is the sister of Caroline Sekar. They were part of a tight-knit group of women who became friends at Stanford University and regularly met for ski trips.

“These are two of the best people I’ve ever known,” Clabaugh and Sekar’s brother, McAlister Clabaugh, told the Times.

“They were incredible sisters, mothers, wives and friends. And the idea that they are both gone is, I don’t even know how to put it into words,” he added.

Carrie Atkin lived in the Tahoe area with her husband and kids. Atkin’s husband, Pete, said his wife had been living her dream life before the avalanche.

“The kids and I are shattered by this tragedy,” he told the Times.

“But even in our grief, we are committed to living a life that would make her proud — a life filled with the adventure, kindness and dedication to others that defined her.”

The tragedy unfolded on the final day of a three-day excursion led by Blackbird Mountain Guides north of Lake Tahoe.

Four guides and 11 clients were struck by the avalanche around 11:30 a.m. Tuesday, authorities said.

The snow slide prompted a desperate rescue mission, with nearly 50 first responders heading to the scene using snowmobiles, snowcats and personal skis. Six of the 15 people were rescued — five women and one man — aged 30 to 55.

While eight people have been confirmed dead, a ninth is still missing and presumed dead.
