Talking Mountain Cirque: Perspectives and Lessons after 34 years
Join us in giving a warm welcome to Lynne Wolfe for her first official episode as a host with the Avalanche Hour Podcast as she shares a thoughtful and reflective conversation with Eric Trenbeath and Brad Meiklejohn. A lot has changed about the avalanche industry in 34 years, but one thing we will never lose is the presence of uncertainty when we make decisions in avalanche terrain. On February 12th, 1992, an avalanche occurred in the Talking Mountain Cirque of Upper Gold Basin in the La Sal Mountains of SE Utah. This accident involved six expert-level backcountry skiers and tragically claimed the lives of four: Mark Yates (contacted UAC Forecaster), Maribel Loveridge, Jeremy Hopkins, and Bill Turk. The group reflects on the terrain, snowpack, and heuristic factors that contributed to this incident, expanding these ideas to similar trends they see continuing in our community today and offering these lessons as learning opportunities for us all to bring into the mountains. The biggest takeaway: maintain a sense of wonder and be ready to be surprised by how snow behaves.About our host and guests: Lynne Wolfe is a retired Teton guide, editor of The Avalanche Review, and she teaches a few courses a season for AAI in the Pro program. She lives in Driggs, Idaho, with husband Dan Powers and the Lucky Dog. She can be influenced by offering dark chocolate, thick coffee, or hazy IPA.Brad Meiklejohn worked at the Utah Avalanche Center from 1983 - 1992. He has been Alaska State Director of The Conservation Fund since 1994.Eric Trenbeath was born and raised on the Wasatch Front. He lived and worked in Alta, Utah for 10 years starting out as a live-in cook at the Goldminer's Daughter before landing a job on the Alta Ski Patrol. Equal parts desert and mountain lover, he has worked as a UAC forecaster in the La Sal Mountains near Moab for 16 seasons (1999-2003, 2013-present).

Stronger Together: Building Intuitive Expertise Where Mountain Miles Meet Mental Miles
Science and experience-built intuition are a composite - they are stronger together than they are separate, especially when we start to see things that we have never seen before. Join Gabrielle Antonioli and Karl Birkeland for an expansive conversation on the critical factors we weigh each day: uncertainty, decision-making scales, and a reflective discussion on how we are strongest when we embrace both sides of the avalanche industry. A snow scientist might not make the best guide if they only stay in the lab but field practitioners need a cross-referenced resource to better face & understand an increasingly dynamic and variable snowpack/climate where outliers are increasingly becoming the new normal. These thoughts are what prompted Karl to write The Starting Zone Book for practitioners, scientists, and everyone in between. Conversation Highlights:- There is uncertainty in all of our assessments, but as we better understand the science behind avalanche mechanics, we can better understand the uncertainty that remains in our assessments required to make decisions in avalanche terrain. - Science is having a structured process for your curiosity - Be a super-forecaster: comfortable with uncertainty and always looking to disprove your hypothesis- Use your intuition to tell you the snowpack is unstable - collect information that disproves your hypothesis.- Effect of temperature on dry-slab avalanche mechanics. Assumption: warmth = more reactivity? Not necessarily. About our host and guest:Gabrielle Antonioli is the current director of the Payette Avalanche Center. Her career started with simply being a curious and avid backcountry traveler—and by asking plenty of questions to Karl Birkeland and the forecasters at the GNFAC. She began as an intern at the GNFAC, and rooted a career in teaching recreational and professional avalanche education courses while completing coursework for an MS in snow science. Following that thread of curiosity and interest in snow expanded to forecasting for the Going-to-the-Sun Road, the Bridger-Teton Avalanche Center, and brought her to her current position. She also manages the A3 Resilience Project.Karl Birkeland has worked with snow and avalanches for the past 45 years, including as a ski patroller, backcountry avalanche forecaster, avalanche researcher, and as the Director of the Forest Service's National Avalanche Center. After retiring from the Forest Service three years ago he set out to - in the words of a friend - ruin a perfectly good retirement by creating an electronic resource for avalanche professionals. Karl has been recognized by his peers with the American Avalanche Association's Bernie Kingery (2008) and Honorary Membership (2024) Awards.Resources mentioned in the interview:Conditions for Intuitive Expertise: A Failure to Disagree (Kahneman and Klein)The Fundamental Processes in Conventional Avalanche Forecasting (Ed LaChapelle) Scaling Issues in Snow Hydrology (Gunter Bloschl) The Starting Zone - By Karl Birkeland 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

Looking Back and How to Look Forward with Dan Abrams
Caleb Merrill is back to interview Dan Abrams for a reflective conversation on a tragic avalanche accident. Tune in for a conversation that stems from the soul…. soul skiing that is, and the endless search for those perfect powder turns that brings our small community of soul skiers & riders together. Dan and Caleb center the conversation’s focus on recounting the Tunnel Creek avalanche accident that Dan was involved with back in 2012. This accident was followed by significant media coverage and quickly drew attention across the country. The New York Times eventually produced a Pulitzer Prize-winning multimedia feature called Snow Fall: The Avalanche at Tunnel Creek about the accident, produced by reporter John Branch. Dan reflects on the lessons he learned from this event and how it has shaped his life today. He highlights that we should put greater focus on our motivations or expectations for a backcountry touring day and how we should change our plans to better align with those goals. We should also make sure we fully read and understand the public avalanche hazard bulletin before leaving the trailhead for a tour and make sure we do not let human biases veil our ability to identify red flags. Dan is a co-founder of Flylow, a ski apparel and gear brand founded in 2004 by two college friends who were self-proclaimed ‘ski bums’ that wanted to create backcountry ski pants that could hold up to the demands of the sport and terrain. Key Moments from the Conversation- Dan recounts and reflects on his involvement with the Tunnel Creek Avalanche Accident near Stevens Pass, WA back in 2012- The most important part before going into the backcountry should be fully reading the avalanche hazard bulletin and checking the excitement levels so red flags are not overlooked. - Pay attention to group size - large groups introduce heightened uncertainty.

Leadership and Culture in the Avalanche Industry
Our next episode is out! Joe Stock sits down with Mik Dalpes for a conversation centered around leadership and culture in the avalanche industry. Mik grew up in Minnesota where she formed a passion for skiing. Her career includes spending time as a ski patroller, Outward Bound Instructor, Park Ranger, avalanche educator, and Avalanche Forecaster for the Chugach National Forest Avalanche Center. Mik had 2 children along the way and has become very interested in what types of leaders and cultures make people thrive in the avalanche industry.Interview Highlights:- Good leaders build a culture that is healthy, which includes treating people the same, handling mistakes well, and having a good balance of confidence and humility- Women should be treated the same as any other person who has a medical condition when they are pregnant and breastfeeding- A wide variety of skills are needed to be an avalanche professional and equal value should be placed on all of these skills including emotional and social skills.Resources from the conversation:- Women and Leadership Conference- Parenting Resource - "Is it a Man's World?"Thanks to the sponsors of the show.Legacy Sponsors:Darren Johnson Avalanche Education Memorial FundAVSSDrone AmplifiedPartner Sponsors:CIL AvalancheSafebackonX BackcountryEpisode Sponsor:Open SnowMusic: KetsaArtwork: Mike Tea Production: Caleb Merrill, Angie Lake

Hot Takes and Friendtorship with Moxie Mountain Guides
Be More Selective, Not More Careful: Hot Takes from the Avalanche Industry Interview Highlights:- A terrain-first avalanche education reset: clear language, fewer false certainties, better decision framing.- Real-world mentorship you can actually build: “friendtorship” structures, debrief prompts, and partner feedback that scales from rec to pro.- Inclusion that’s operational, not performative: how All In Ice Fest trains guides and changes who feels welcome (and safer) in mountain spaces.Jason Antin sits down with Kristin Arnold and Sheldon Kerr of Moxie for a candid, wide-ranging conversation that starts at All In Ice Fest at the Ouray Ice Park—and quickly moves into some very real hot takes on the snow and avalanche industry. Tune in to hear Kristin and Sheldon pull no punches as they share experience-backed perspectives on avalanche education, decision-making, and the systems we’ve built around them.Along the way, they unpack how All In has grown into a major gathering designed for BIPOC, adaptive, LGBTQ2SIA+, and neurodivergent communities—and how centering training and leadership development within those communities reshapes what access, authority, and representation can look like in the mountains.The conversation then drills into the core of their teaching philosophy: terrain management first, valuing consequence over likelihood, and acknowledging that humans are fundamentally bad at probabilistic thinking (and that this is not a moral failing). They explore “friendtorship” as a more honest alternative to the mythical mentorship pipeline, the outsized impact of short, consistent debriefs, and why being more selective consistently beats trying to be more careful in complex snowpacks.They wrap with a series of lightning-round moments—including a spirited debate on beacon harness vs. pocket carry, why avalanche accident analysis often gets overcomplicated, and each guest’s Personal Disaster Flag: the human-factor tendencies they actively manage to stay sharp in the field.About our guests:Kristin Arnold (she/her) and Sheldon Kerr (she/her), from Ridgway, CO, are the owners and lead guides of Moxie Mountain Guides. As of spring 2025, they are 2 of 19 total women AMGA/IFMGA guides in the U.S.* Kristin and Sheldon started Moxie in January of 2023. As Moxie, they’ve guided skiing on Chilean volcanos, taught rock climbing clinics all over the Western US, built risk management plans and forecasted avalanches for Colorado silver mines, trained US Special Forces teams in mountain skills, instructed professional avalanche courses all over the country, and worked with small businesses and national organizations to improve their diversity, equity, and inclusion programs.Both Arnold and Kerr are also on the Instructor Team for the American Mountain Guide Association, staff members of the American Institute of Avalanche Research and Education, and graduates of Habit Queer’s Fitness Beyond the Binary certification program. They have also completed training through Paradox Sports in working with adaptive athletes.Resources discussed in the episode: All In Ice FestMoxie Mountain GuideThanks to the sponsors of the show.Legacy Sponsors:Darren Johnson Avalanche Education Memorial FundAVSSDrone AmplifiedPartner Sponsors:CIL AvalancheSafebackonX BackcountryEpisode Sponsor:ArvaMusic: KetsaArtwork: Mike Tea Production: Caleb Merrill, Bob Keating
