This article was originally published on Powder.com Every little grain of snow changes dramatically, sometimes in a matter of hours, as a result of subtle changes in temperature and pressure. As skiers and riders, we all know snow. It blankets the mountains with deep powder during the cold winter months offering endless ground for play. But what if I told you that snow is actually a “warm” material? It’s not just warm, it’s hot! Sounds crazy, but understanding this concept can help unlock the science of snow. It can help us understand why powder conditions or …

The million dollar question: This time of year, everyone wants to know how much snow we'll get. What are the predictions? My standard response is that it's going to be a huge winter! Why not? We're all eternal optimists, and I was right last winter which went beyond record breaking to nearly historic levels. So, really, what about this coming winter? There are a few things we can say. It's an El Nino winter. According to the Climate Prediction Center of the National Weather Service (NWS) - "El Niño is anticipated to continue through the Northern Hemisphere winter …

This article orginally appeared in BackcountryMagazine.com on February 1, 2019 How quick pits improve decision-making In another article on BackcountryMagazine.com, Sarah Carpenter described six steps for doing a “quick pit” and answering the question “Am I missing anything?” Make sure to read if you haven’t already. I’d like to offer a few reasons to dig a quick pit, including how it helps our decision making. In mid-December I was skiing on Kessler Peak in the Wasatch Mountains. Strong winds had ruined the skiing on many slopes, and we were searching for …

Springtime in the mountains is one of the best times of the year. Longer days and lots of sunshine bring on great corn riding, bigger objectives, and changing avalanche problems. While those pesky weak layers we’ve been worrying about all season start to become dormant, we begin turning our attention to wet avalanches. While these avalanches are harder to predict than dry avalanches, a few signs can indicate the potential for these slow yet powerful slides to release. Recent wet avalanche activity, roller balls or ‘cinnamon rolls’ beginning to fall down the mountainside, …

What does Acceptable Risk even mean? Not long ago, I was asked this question by another long-time avalanche professional after sitting in one of our annual fall Snow and Avalanche Workshops. In an avalanche accident this winter, I found - what I believe - to be a clear example. First some definitions (these are my definitions): Risk - the potential of danger, harm, or loss to someone or something. In the mountain setting, risks may involve injury or death due to the interaction with objective hazards, such as rockfall, lightning, or avalanches. Reward - …

Spring has sprung and we’re just now passing the max SWE (snow water equivalent) for Snowbird (black line) for this time of year. Not that we needed a chart to know that this is the type of season that keeps people in Utah for decades. You can tell by the smiles on riders’ faces, and talking to friends who are too tired to keep skiing, but keep after it because it’s that good. There are decisions being made right now that will change the path of someone’s life long into the future and they involve sliding on snow in the mountains. So simple- yet so rewarding. It was …

Avalanche transceivers are susceptible to interference by electronic devices, metal objects, and magnets if they are too close. Every day there are more electronic devices being carried into the backcountry. Of particular concern may be heated clothing. The guidance below provides practical guidance on how to avoid problems with interference. It was created through a collaboration by Avalanche Canada, the US National Avalanche Center, Colorado Avalanche Information Center, Utah Avalanche Center, Northwest Avalanche Center and the six avalanche transceiver manufacturers: Arva, BCA, …
