Greetings:
The Gallatin National Forest Avalanche Center just wrapped up 26 years of operation. We started the season with the threat of a dry El Nino winter which never materialized and finished with a snowpack measuring close to 100% average. March got almost as much snow as January and February combined.
From the time snow crystals fall from the sky to time they melt in the spring, the shape and structure of each crystal never stops changing. This is known as snow metamorphism.
Snow metamorphism determines if individual snow crystals are rounding (becoming stronger) or faceting (becoming weaker). The relationship between snow crystals ultimately dictates what kind of layer, strong or weak, is formed. The interaction between individual layers determines snowpack stability.

I never thought I’d be concerned about my electronics while cruising around the backcountry, but I am. Carrying a cell phone, satellite phone, GPS, avalanche beacon, SPOT Messenger, and a VHF radio means my electronic signature rivals a high tension power line. I hope I don’t have to start lugging around a car battery to keep everything powered. Most people in the backcountry are not as wired as me, but a smartphone and beacon are staples for most backcountry travelers. The beacon is a literal lifeline, the most important piece of electronic safety equipment we carry. Its function is crucial to survival. As I slowly added to my electronic arsenal over the years I began to wonder, “Do all these other devices interfere with the function of my avalanche beacon?”
The GNFAC is looking for an intern for the 2023-'24 winter season. Application deadline is April 30, 2023.
On September 16th winter arrived with a foot of snow in the mountains. On the 17th a skier triggered the first avalanche of the season. On the 19th, after continued snowfall, Alex issued the first avalanche information bulletin, the earliest in 28 years of operation. This winter was the biggest snow year since 1996/97 in southwest Montana with snowpack depth averaging 120-160% of normal.
Chris Lundy, owner of Sawtooth Mountain Guides, wrote a great article in Backcountry Magazine about digging pits. He opens the story with a personal account of triggering an avalanche. I was with him that day. We triggered the slide up Fisher Creek outside Cooke City on March 10, 2002.
There are no stoplights in the backcountry. The decision to ride into uncontrolled-avalanche terrain is a personal one with risks and rewards. Done correctly, pinning the throttle through a field of untracked powder or climbing a steep mountain face can produce unmatched excitement, but riding in avalanche terrain can produce severe and sometimes deadly consequences.
