It was mid-October when backcountry skier
Elliot Natz set out to ski Gem Lake Couloir in the Bitterroot Mountains.
Stubborn summer warmth lingered and it was a balmy 40 degrees and slightly stormy.
As Natz approached the top of the chute, he heard the echoes of falling rocks.
A series of small, wet snow slides cascaded down his path, burying him up to
his waist. Suddenly alert, he wriggled himself out of captivation and escaped
to safety.
Natz is more fortunate than the 25 to 30
people who die in avalanches each year in the United States. In fact, snow
slides are reportedly the deadliest natural hazard in our national forests.
However, when people make the choice to
venture into the backcountry in spite of the looming risks, even in the spring,
they can rely on one key resource: avalanche forecasts.
Todd Glew is an avalanche forecaster for the
West Central Montana Avalanche Center in Missoula. A few days a week, he and
fellow forecasters throughout the state compose area-specific reports known as
avalanche advisories. The advisory evaluates the safety of backcountry
conditions on a scale from low to extreme and outlines the concerns of the day.
It’s bolstered with colorful graphics that even the most novice of users can
interpret.
“Our role is super important,” Glew said.
“Checking the forecast is imperative to anyone heading into the backcountry.”
The forecasters follow weather patterns
closely, and when in the field, they perform a series of tests and observations
that inform their reports. Their process is typically much more thorough than
the average backcountry recreationist, making the avalanche advisory an
essential tool.
As Montana transitions from winter to spring,
forecasting practices change slightly.
“When we are in a full spring regime, we are
digging pits and taking temperatures,” said Doug Chabot, director of Bozeman’s
Gallatin National Forest Avalanche Center. By focusing on temperatures, the
forecasters can establish if the snowpack is above freezing—a spring condition
that can potentially instigate large and hazardous wet slides.
Chabot acknowledges that spring can be an
ideal time for backcountry recreationists to set their sights on more
aggressive lines, but risk is still present.
“People need to remember that all the standard
rules apply,” he said. “You want to always carry your avalanche rescue gear,
you want to always have a partner and you want to always go one at a time.”
Chabot also recommends backcountry missions be limited to earlier morning
hours, when the snowpack is still frozen. Getting caught in avalanche terrain
as afternoon temperatures rise can put you at risk for triggering a wet slide.
Part of a forecaster’s job is passing on their
wealth of knowledge to others. Backcountry skiing is the first thing Glew
remembers doing when he moved out west from his home in Boston, but he knew he
wanted to do more than just ski.
“I realized I also wanted to teach,” he said.
Glew was able to combine his passions working as an educator for avalanche
centers in the Salt Lake City area as well as Missoula. He continues to do
community education through avalanche classes and public events.
Although Glew loves his job, avalanche
forecasting comes with stresses. The avalanche advisory is no perfect science,
though many people use it as such.
“The spatial variability of it all is tough,”
Glew said. The West Central Montana Avalanche Center advises for over 900,000
acres of space. Conditions vary slope to slope, and they can differ
tremendously.
Dealing with a complex snowpack that has been
influenced by unique weather patterns also poses a challenge. Glew calls this a
“grey area.” “You’re trying not to shoot too high [or] too low in your
forecast,” he said. After all, the consequences can be deadly.
Backcountry recreationists are encouraged to
use the forecast as just one tool in their belt and to combine the information
with their own observations and tests. Still, the margin for error or poor
decisions can lead to the ultimate tragedy.
“You have to be okay with always knowing there
are risks,” he said, remembering many of his friends that have fallen victim to
snow slides. For Glew, there have been instances after losing people he cared for
when he wanted to give up his work with avalanches altogether. What keeps him
in it is selflessness.
“I feel like I’ve been doing this long enough
that if I were to leave, I’d be doing a disservice to the community,” he said. “I
definitely think you can take the bad stuff to heart, but you just try and do
the best job that you can.”
The National Avalanche Center estimates that
in the entire country, there are only around 170 part-time and full-time forecasters,
many of whom only work in-bounds at ski resorts. The pay isn’t outstanding,
Glew says, and many people are turned away because of this. There are few
individuals who are outfitted with enough experience and education to be a
qualified avalanche forecaster.
