UTAH AVALANCHE FORECAST CENTEROur PhilosophyUtah - A Different Kind of Placeby Bruce Tremper |

There's also plenty
of other places on Earth which have "greater" snow but nobody lives there. How
can you say that the interior of British Columbia doesn't have the Greatest
Snow on Earth? The helicopter companies have been making a fortune on their
snow for years. But Utah lays claim to the Greatest Snow on Earth mostly because
there's so many people here to ski it and promote it so that even more people
can ski it. There's a million people who live smack at the bottom of the Wasatch
Range - all within a 15 minute drive to the ski areas.

Maybe you don't consider
a million people plus a big, steep, snowy mountain range famous for its
snow to be a lucky combination. But if you're an avalanche forecaster
you certainly do. There's 12 ski areas crammed together, six of which could all be connected together into one giant ski area with the addition of just two more chairlifts. With open borders at all the ski areas this also means very easy access to the backcountry, which turns it into what I call an urban backcountry. After a sunny powder weekend, you can hardly find any slopes in the entire range which are not completely tracked out. There's literally moguls on many popular slopes. With people crawling all over this little mountain range it also means that there are no secrets in the Wasatch. No secret powder stashes, no secret extreme descents and no secret avalanches. Either they call us right away or it travels down the canyons thorough the grapevine, eventually we hear about most of the avalanche activity within a couple of days. |

If that's not enough, each of
the 12 ski areas and the Utah Department of Transportation have their own avalanche
teams with their own battery of automated wind, temperature and precipitation
gages. The Utah Avalanche Forecast Center computer calls each of these 15-20
automated stations every hour, every 15 minutes
in many cases, and the data instantly appears on our computer monitors and on
the Internet. With the Olympics coming in four more years, there's another 10-15
more automated stations yet to be installed. We also talk to all the avalanche
directors each day from each ski area, DOT and helicopter skiing company, either
over the phone or via computer. And we talk to about 15 of our own backcountry
observers which we pay about $10 per day to call information into us. Then there's
the State Parks snowmobiler groomers which report conditions each morning. Did
I mention that our staff of seven spends half of our working hours in the field
as well? Perhaps you're getting the idea here. There's an astounding density
of avalanche and weather information in
northern Utah. Perhaps more data from a relatively small mountain range than
anywhere else on earth. Lucky for us.
Because of this luxury,
our avalanche bulletins can contain a large amount of detail. We never give
blanket avalanche danger ratings (there's a moderate danger in the Wasatch Range
today). We not only give customized forecasts for each section of the range
but also for separate canyons and we break it down a certain terrain description,
for instance aspect, elevation, steepness, amount of wind loading, anchoring,
etc. Each day we know that hundreds of people will go into the backcountry and
it's our job to communicate the pattern of instability we see. In other words,
avalanche danger is almost never uniformly spread over a mountain range, but
it varies according to all the usual terrain parameters, aspect with respect
to wind, aspect with respect to sun, steepness, elevation, slope shape, anchoring
or any other pattern we see. And the finally luxury of large numbers of people
afoot in the backcountry is that you find out very quickly if you're wrong.
The Delivery
But just because people
hear it doesn't mean they listen. In other words, if it sounds like a government
recording, people get bored, they won't remember what you say, and they just
quit calling after awhile. Our philosophy has long been to present the recorded
avalanche bulletins in an entertaining way so that people will most likely remember
what they hear. We have become rather well known for making our advisories fun
to hear. We try and
use all the standard tools of effective writing and speaking such as using active
voice and first person, using examples and stories to illustrate points, using
humor where appropriate, and reading the advisories in a natural voice, like
talking to a friend. They're informal, chatty and funny yet informative. But
we do it mostly because it makes our job fun.
We also deliver the
message in several different ways to accommodate a public with a wide range
of avalanche skills and a corresponding wide range in need for detail. There's
a simple, easy-to-grasp one-page graphical presentation of the avalanche danger
scale available on the Internet and by fax (available for the first time this
season). This is the winter equivalent to Smoky the Bear which lets people know
the general avalanche danger at a glance. After that, we do a more detailed
live interview on two different public radio stations each day. Finally, for
those who need lots of detail, we record seven different customized bulletins
for each section of the northern Utah mountains and also the La Sal Mountains
near Moab. In the heavily used Salt Lake City area, we have two recordings-a
three minute and a very detailed six minute recording.
We Keep Our Noses
in the Snow
We also believe in diversified
avalanche forecasting. In other words, local forecasts recorded by local people.
Avalanche forecasting is much more of an art than it is a science. And because
of this, computers never have, and most likely never will, be able to forecast
avalanches. For instance, how are you going to design a robot which can ski
around in avalanche terrain, dig snowpits, feel the snow, smell the wind, feel
the mood of the day, make friends with all the other people in the backcountry
and get them to call in important information to you, make friends with all
the other avalanche workers and cooperate closely with them, access 40 years
of personally-stored data, integrate all the pieces of data together and creatively
write and deliver an avalanche advisory? This is a job that only a human can
handle, and not by sitting in an office all the time.
We believe that whoever
records the avalanche advisory must have been in the backcountry looking at
the snow in the previous day or two. We usually don't go to ski areas except
to access the backcountry because the snow inside the ski areas gets skied and
bombed so much it often bears no resemblance to the backcountry. We also don't
forecast for places which we do not visit on a regular basis for the same reason
that a bowler won't be very good if they can't see the pins. In both Logan and
Moab, local people record the local advisories. The Salt Lake based staff of
six simply can not visit Logan and Moab often enough to know what's going on.
The Salt Lake staff covers from Ogden to Provoabout an 80 mile section of the
Wasatch and Uinta Mountains and by far the most heavily used section. A part
time staff of three records the bulletin in Logan three times per week and the
Salt Lake based staff records it the remainder of the week. (We hope next season
to have enough money for local Logan staff to record the bulletin 7 days per
week.) In Moab one full time forecaster issues bulletins for the La Sal Mountains.
The New Kids
on the Block
Finally, the demographics
of avalanche victims have changed significantly in recent years. If we look
at the most recent five years of data, we see that snowmobilers lead the list
of avalanche fatalities followed by climbers and then by backcountry skiers.
Snowmobilers especially make the perfect avalanche trigger not only because
they weigh more; because of advances in power, traction and lighter weight,
snowmobiles can go virtually any place a skier can and they can cover 100 times
the amount of terrain in a day than a skier. Likewise, snowboarders are rising
rapidly on the list because they can access the backcountry more easily with
the recent invention of split apart snowboards and lightweight and high-tech
snowshoes. Also, there's a lot of crossover in the sports. It's not unusual
to ride a snowmobile into an area to access skiing, boarding and climbing terrain.
Sometimes you do all four sports in the same day.
The changing demographics
have not been easy for us. Being skiers and climbers by training and choice,
we have had to tame whatever deep seated bigotry we may have had towards the
newcomers in the backcountry. We've all learned to ride snowboards and we increasingly
climb aboard the hung-clogging, stink-belching, eardrumshattering snowmobiles.
OK, I didn't say we had to like snowmobiles, but we have had to adapt to stay
current. We're hiring more snowboarders and snowmobilers as observers and instructors.
And we're designing and teaching courses especially for them. Turns out that
underneath the helmets and baggy pants they're people just like us. Imagine
that.
This is our philosophy and it seems to be working. More people call the UAFC
recorded bulletin each year than any other avalanche service in North America,
and the number keeps increasing each season by 10-20 percent. There's also an
insatiable demand for avalanche education and avalanche information by not only
Utahns but by the national and international media. For whatever reasons, we
end up on TV alot, and we take each one of these opportunities to "preach the
avalanche gospel." Which is good because we barely have enough money to run
our program each season, much less run a national or even local public relations
campaigns-to educate the masses about avalanches.
I guess we shouldn't
complain. The public likes us, we save lives and we love the work. Now if there
were just some money in it. It would be the perfect job.
