One rider was not buried and did not suffer any injuries, but immediately called 911 after realizing the other — who has since been identified as Kitto — was calling for help. The CAIC said Kitto "sustained multiple injuries" after being dragged into the trees and getting "partially buried in the snow." He was later airlifted to a hospital but died from his injuries. In a press release from Bozeman Public Schools in Montana, Interim Co-Superintendents Marilyn King and Casey Bertram said they were "saddened" by Kitto's death. Kitto's wife Lana also spoke out about the tragedy to CNN, explaining that her husband had been the principal of Whittier Elementary School in Bozeman since 2018. 15 People Die in U.S. Avalanches in 7 Days — Why It's the Deadliest Avalanche Period in a Century "He was a servant to everyone and always put others first," Lana told the outlet of her husband, whom she said had an "authentic connection with kids" and "lived to love" her and their daughters. "He was a tireless hard worker and no task was too big," she continued. "His desire to live big took him out in a big way. I will love and miss that constant adventuring with him by my side." On the same day that Kitto was killed, two more avalanches struck in Colorado, according to the CAIC. One involved a backcountry snowboarder, who was traveling alone and got caught and buried in an avalanche around 9:30 a.m. on a terrain feature known as Pat's Knob, east of Mount Trelease, the CAIC stated. "Searcher and Rescue personnel found the tourer buried with a deployed avalanche airbag. Part of the airbag was visible in the avalanche debris, but the tourer's head was covered," the CAIC wrote, noting that the snowboarder ultimately died. Authorities later confirmed his identity as Heide, according to CNN.

After the avalanche stopped, the CAIC said the snowmobiler became buried underneath his sled on Pumphouse Lake and later died. His identity remains unknown at this time. So far, 18 people have died in avalanches across the U.S. this month, with Colorado as the site of four of those fatalities, according to the CAIC. In the 2020-2021 season alone, 25 people have died in avalanches, the CAIC reported. Just last week, the United States marked its deadliest week of avalanches in more than a century after more than a dozen people died in the snow disasters across Washington, Utah, Colorado, New Hampshire, Montana, California and Alaska. Experts believe the avalanches are due to a weaker base layer of snow, and the rise of outdoor activity as more people take to the mountains amid the ongoing coronavirus pandemic.
