Wendy’s Wisdom: A Tribute to Wendy Wagner
In loving memory of a legend from our community, we dedicate this episode to you, Wendy. From Wendy's family: '“I don’t get tired, I go hard!” Are the words six year old Wendy said to her uncle when on a hike. That was the way Wendy lived her life and achieved her dreams. The rest of us felt so lucky to scramble, climb, pedal, ski, or snow machine behind her, trying to keep up on another Wendy adventure.Wendy was born on October 31, 1973 in Salt Lake City, Utah and she touched the sky on November 6, 2025 in Park City, Utah under a super moon, giving us a fresh dusting of snow on the mountains. Wendy accomplished so much in her life. An incomplete list: 2002 and 2006 Olympic Winter Games athlete in cross country skiing, 4 World Championships participation, 6 National Championship wins, a coach at the University of Utah XC ski team 2006-2008, an intern for the Utah Avalanche Center, a master’s degree in atmospheric science from University of Utah leading to a career in avalanche forecasting, the Director of the Chugach National Forest Avalanche Information Center 2010-2025 and an air resource meteorologist for the US Forest Service deployed to wildfires.But beyond these amazing achievements, the most significant, however, is her sincere and genuine smile, infectious laugh and the positive energy behind it that had such an impact on so many during her life with us. She was the rock that drew the best out of all of us. She was a force of nature that we will all miss. Her spirit will stay alive in all of the hearts she touched. Energy doesn’t die, it transfers."A note from Andrew Schauer at the Chugach National Forest Avalanche Center:"[Wendy] shared with us at our last staff meeting just last week, that people had been asking her what’s on her bucket list? She said the only thing she wanted to do was “work at the avalanche center with all of us”. She has built something remarkable, and we are lucky to be able to carry the torch. Wendy set an incredibly high standard for trust and respect among our team and within our community. During her 15 seasons at the avalanche center, she built a solid foundation of partnerships and systems that will benefit our community well into the future. See Andrew's full note here. A few stats about Wendy:- She started at CNFAC during the 2010/11 season- 742 forecasts- First Chugach Avy fx: 02/06/2011- Final Chugach Avy fx: 04/13/2025 (High danger, P1: Storm Slab/ P2: Deep Slab!)- 452 observations- First Chugach Avy Obs: Seattle Creek 11/20/2011- Final Chugach Avy Obs: Seattle Creek 3/15/2025"Thanks to the sponsors of the show.Legacy Sponsors:Darren Johnson Avalanche Education Memorial FundAVSSDrone AmplifiedPartner Sponsors:CIL AvalancheSafebackonX BackcountryEpisode Sponsor:IPA CollectiveMusic: KetsaArtwork: Mike Tea Production: Caleb Merrill, Bob Keating

Jake Hutchinson x Tom Kimbrough - Conversations with Maestro
In Episode 10.3, Jake Hutchinson sits down with Tom Kimbrough to bring us our first Bio of a Legend this season. Roshi is the Japanese word for “zen master” or “old master.” For a generation or two of Wasatch avalanche hunters, Tom is both the old master and the zen master. His holistic approach to assessing risk in snow covered mountains is a culmination of a life as a curious avalanche hunter, public forecaster, climbing ranger and avalanche educator.Tom’s career spans work on the Alpine Meadows and Alta Ski Patrols, a Jenny Lake Climbing Ranger, forecaster at the Utah Avalanche Center and instructor for the American Avalanche Institute. One of the first things Kimbrough learned about climbing was that climbers tended to be skiers in the winter. After a season on the lift crew at Badger Pass in Yosemite he graduated to the ski patrol. Soon he was patrolling at Alpine Meadows in Tahoe. Alta was next on his list and in 1987 he began working for the Utah Avalanche Center. He finished his avalanche career with Rod Newcomb’s American Avalanche Institute.In this episode, Jake and Tom talk about:The 1982 Alpine Meadows Avalanche AccidentHumility in the mountainsZen and the art of avalanche forecastingA note from Jake: “More than once we mention Rod Newcomb in this episode. Between sitting down with Tom and the release of this episode, we lost Rod at the ripe old age of 91. Rod was a friend, mentor and pioneer in our industry. He shaped avalanche education in the US and was the first to see the need for pro specific education. His influence on Tom, myself and so many others cannot be overstated. A long life fully lived, thanks for everything Rod.”Thanks to the sponsors of the show.Legacy Sponsors:Darren Johnson Avalanche Education Memorial FundAVSSDrone AmplifiedPartner Sponsors:CIL AvalancheSafebackonX BackcountryEpisode Sponsor:Avalanche Risk SolutionsMusic: KetsaArtwork: Mike Tea Production: Caleb Merrill, Bob Keating

Dr. Bruce Jamieson x Dr. Scott Thumlert: Merging Theory and Practice
Bruce Jamieson’s interview with Scott Thumlert revolves around Scott’s career in avalanche research, guiding, as well as planning and engineering. Scott recounts anecdotes during his graduate studies of the stress in the snowpack under skiers and snowmobiles, and implications for tests like the extended column test. He discusses a more recent interest in improving the communication of avalanche likelihood and identifies some challenges in developing a new rating system. One of the challenges is validating the frequency of human-triggered avalanches. Specifically, when human-triggered avalanches are more likely, avalanche practitioners and winter recreationists avoid more avalanche terrain, so the number of avalanches available for validating may not increase as predicted. Scott also outlines the potential role of artificial intelligence in improving avalanche forecasting, but feels manual field work will continue to be needed. With colleagues, Scott is working on hazard mapping projects and related research into the effect of forest fires on extreme avalanche runout and hazard mapping for residential areas. As the chair of the technical committee for the 2026 International Snow Science Workshop, Scott outlines a new strategy – developed by the conference organizers - for merging theory and practice and how they plan to get more practitioners presenting case studies and applied research. Key InsightsScott’s graduate research focused on measuring the stress in the snowpack exerted by skiers and snowmobiles, highlighting the relationship between stress levels and triggering of slab avalanches.Effective communication of avalanche likelihood remains a challenge, with more ratings needed for lower levels of avalanche likelihood. While there is promise for improved validation of likelihood ratings, human triggering – which is very important – will remain more difficult than validating the frequency (and likelihood) of natural avalanches. Artificial intelligence has the potential to enhance avalanche forecasting by improving data analysis, but Scott feels avalanche practitioners will still be required to verify the forecast. The International Snow Science Workshop aims to merge theory and practice, encouraging practitioners to share real-world case studies and applied research.Links to papers and resources mentioned in the interview:Assessing and communicating likelihood and probability of snow avalanches.
