Do We Let Our Guard Down in the Spring?
McKinley Talty
Remember Warren Miller’s famous quote, “If you don’t do it this year, you’ll be one year older when you do”? I like to think Warren meant to say, ‘If you don’t do it this spring, you’ll be one year older when you do.’ Spring is a coveted season in the backcountry, and typically, it’s the time of year to go after bigger objectives. As the days become longer and lingering weak layers trend dormant, the avalanche problems often become more manageable. In this perception of safety, however, we continue to see riders getting caught and carried in avalanches. In March 2024, …

Is it Really LOW Danger?

Is it Really LOW Danger?
I have a unique relationship with LOW avalanche danger, especially when LOW is actually MODERATE (but that’s a different story). But there are a few things I have learned over the years about our perception and response to this rare and interesting danger rating and I'd like to share some of those with you.
But first let's back up a bit.
One of our most fundamental risk management strategies - whether we are riding the backcountry, alpine climbing, paragliding, or kayaking - is to adjust our choices (what, how, when, where, with whom) …

Do We Really Still Have a PWL Problem in the La Sals?
Eric Trenbeath
It’s now March and most years our deep, persistent weak layer (PWL) problems are usually turning the corner meaning they have gained strength, or are deeply buried by a strong, overriding snowpack, or both. This is the time of year when we usually start setting our sights on bigger lines once new and wind drifted snow instabilities have settled out. So, what’s going on this season? Why do we remain concerned about weak, faceted snow at the base of the snowpack, and what’s it going to take for those concerns to go away?
To be clear, we are in a “low probability, high …

Wind, Drifting, and Avalanches
Toby Weed
Wind, Drifting, and Avalanches
According to the National Oceanic and Atmospheric Administration, “Wind is the movement of air caused by the uneven heating of the Earth by the sun.” Indeed, other environmental elements are at play, like gravity, fluid and gas dynamics, weather systems, and the earth’s spinning, but causes aside, NOAA is clear, “Wind is simply air in motion.” In the mountains, wind has a considerable influence on avalanche phenomena. Drifting of falling snow and snow already on the ground creates heavy deposits or drifts in avalanche-starting zones. These …

Skyline seasonal snowpack summary 2023-24
Brett Kobernik
The 2023-24 winter season started out fairly normal.
October:
There were a couple of minor snow storms in October that dropped a few inches of snow. This snow melted off everything except the highest north facing slopes. This snow that stuck around faceted (turned to sugary snow) but it wasn't enough to be concerned about as far as acting as a persistent weak layer once more storms came.
November:
The first two weeks of November was dry. Then, a couple of storms moved through, one on the 18th that produced 8" of snow and one on the 24th that produced 10" of snow. …
