Landmines
Drew Hardesty
One of the greatest satisfactions of my career is having conversations with others about this world. With permission, I am reprinting a recent piece of correspondence from an Army officer who is frequently deployed to the middle east.
I spent time in the middle east as a naval intelligence officer in Desert Storm in the early 90s.
Drew,
I hope all is well. It’s Derek, the skier/soldier, we chatted a little last year. Of course my luck, I deployed in March and missed the amazing finish to last season, but so is military life. I’m back and already getting …

Risk, Reward, and The Big Lie - A Conversation with Doug Workman
Ben Bombard
In this podcast, we sit down with Doug Workman. Doug is an alpine guide but is considered the real deal as far as international ski guiding goes. Doug is one of the more thoughtful and insightful people in the mountains that you'll meet and his philosophy on guiding may not be what you think.
Doug Workman has been taking risks on the snow since he was a toddler learning to ski at Powder Ridge in Connecticut. Since then he has found many other places to experiment with risk taking and risk management—Alaska, Pakistan, Iceland, China, Morocco, Svalbard, Antarctica, and in …

When will the Persistent Weak Layer go away
Mark Staples
Brief history:
Snow fell in October and became faceted. In early to mid-November, warm weather formed a crust on top of this layer which remained on north and east-facing slopes. Warm weather melted snow off of south and west-facing aspects. A little more snow fell on top of the crust around Nov 20th, and this snow faceted. All these facets formed the persistent weak layer that is now at the bottom of the snowpack.
When heavy snowfall arrived during the week of Thanksgiving, many avalanches fractured on this persistent weak layer. Some avalanche failed on facets above the crust. Some …

UAC Podcast - Betting Your Life - Why Forecasting is Poker and Not Chess - A Conversation with Jenna Malone
Ben Bombard
In this podcast, we sit down with Jenna Malone. At this fall's Utah Snow and Avalanche Workshop, Jenna gave a compelling presentation on why avalanche decision making is more like poker than chess. In essence, with chess, we can see all the different pieces of the puzzle; one only needs to "outsmart" her opponent. Poker, on the other hand, involves a little bit of luck and the uncertainty of what cards your opponent holds. Not everything is revealed. Inspired by champion poker player Annie Duke's book Thinking in Bets: Making Smarter Decisions When You Don't Have All the Facts, …

Why are some slopes more dangerous than others?
Mark Staples
NOTE: This blog post was written in December 2019 when there was similar weak snow at the ground to December 2020 except when this blog was written, there was a slab of snow on all slopes. This slab was an avalanche problem where the weak snow existed underneath it. As of December 5, 2020, most mountain areas in Utah have weak snow at the ground but no slab on top of it to produce an avalanche.
In many areas of Utah, the main avalanche problem that is causing large deadly avalanches is a slab of snow resting on a persistent weak layer of faceted snow. That's a mouthful. What …
