Skiing far from the road, in areas without a professional avalanche forecast, is the essence of backcountry skiing in Alaska. In these remote areas, uncertainty is high and the adventure dial is on max. Compared to the relative safety of roadside skiing, more technical knowledge, more experience, and a different mindset are needed.
I’ve been skiing in remote Alaska for thirty years and trying my best to avoid avalanches the entire time. So far I’ve been lucky, but it’s not wise to depend on luck for safety. To avoid avalanches, my goal is to ditch the luck part and rely more on knowledge, experience, and a better understanding of uncertainty to manage avalanche risk. This is a work in progress. I’m perpetually questioning and rethinking the avalanche problem. So please get in touch and share your ideas if this article resonates. I’d love to hear from you.
In this article I present a process for avoiding avalanches in remote Alaska. It’s a series of steps to go through on each trip. The process starts with training in the years before your trip, and planning in the weeks before the trip. Once in the field, it’s an ongoing cycle of observing conditions, forecasting avalanches, building route options, and adding margins for safety. A mindset of embracing uncertainty ties this backcountry cycle together in the field.
The Forecast
At roadside backcountry ski regions of Alaska, like Turnagain or Hatcher Pass, the professional avalanche forecast is a baseline of information before going into avalanche terrain. A team of highly skilled avalanche professionals build the forecast, like at the Chugach National Forest Avalanche Information Center or Hatcher Pass Avalanche Center. Their job is to assess avalanche conditions, consolidate observations from the community, and to present the information to the public in usable form. In regions without a professional avalanche forecast, you become the forecaster. You must do all the work of a forecasting team. Skiing in regions without a professional forecast is a different mindset and way of operating.
Training
The first part of skiing in remote Alaska is training. Skiing in remote Alaska requires a lot of training. Of course you need good fitness and riding ability to move around. Gain backcountry skills through a progression of backcountry trips, so going into remote Alaska isn’t a big jump. You also need avalanche skills. The Recreational Level 2 avalanche course is geared toward being your own forecaster. It is said that without a Rec 2 you’re like a one-legged man in an ass-kicking contest.

With the training you also need experience and practice. Experience adds data to your mental database allowing you to make better decisions by recognizing situations. Deliberate practice is where the learning really happens though. Deliberate practice is painful, type two fun. An example of deliberate practice is turning around before the summit because of avalanche conditions, or digging a two-meter hole in hard snow for rescue practice, or taking an avalanche course rather than going skiing. It isn’t exactly fun at the moment, but it’s how we learn best.
The second part of skiing in remote Alaska is planing your trip. This starts in the months and weeks before the trip. There is a surprising amount of information about weather and snow conditions in remote Alaska including remote weather stations, aviation cameras, trip reports, etc. Alaska adventurer Luc Mehl has a great weather resources page on his website (thingstolucat.com/ddtp-weather-resources). Pilots are another great resource as they know current conditions in remote Alaska better than anyone. I often won’t decide exactly where to go until we’re leaning up against a loaded plane and I’m drilling the pilot for information.

Part of planning is forecasting the avalanche danger and problems you may encounter. Make a guess based on the information you found. Was there a big recent storm that may have dumped five feet on top of a persistent weak layer? Was it a drier than normal season? Spring is the ideal time to ski in remote Alaska because the days are long, snowpack is deep, temps are warmer, and there are less persistent avalanche problems.
Before the trip, be armed with several entirely different trips options. Alaska adventurers know that staying flexible with trip options is fundamental to trip success in Alaska. For example, your first choice may be the central Chugach, but if it’s a raging storm there be ready to shift to the central Talkeetna Mountains. Fixating on one trip option is setting yourself up for disappointment. Select places that have a range of terrain options. From simple terrain for elevated avalanche danger, to complex terrain for low danger.
Even as you head into the backcountry, things will not go as planned. My favorite is when flying into a remote area that we’ve been planning on for months and the pilot says, “Sorry, we can’t land there.” That means I get to window shop for a new place. The adventure level just went up another notch. Embracing adventure, the unknown, and uncertainty is what feeds the Alaska adventure addict. If you want things to go as planned, ski somewhere besides Alaska.
In the Backcountry
After training and planning, it’s time to move into remote Alaska by air, boat, snow machine, or good old human muscle. To avoid avalanches while in the backcountry, use an ongoing cycle of observing conditions, forecasting avalanches, building route options, and adding margins for safety. These steps build upon the planning you did before the trip: it’s a continuum of studying conditions and routes.

Embracing uncertainty is the common theme that ties this backcountry cycle together. In the snowy mountains we don’t know exactly what going in the snowpack. In remote Alaska, without a professional forecasts, we know the least. Like life in general, we rarely have a clear choice when making a decision, unless we only use data that supports our bias. Eliminating bias is impossible, even says the world authority Daniel Kahneman, so we need to adapt ways to work with bias to minimize its negative effects.
One useful technique to embrace uncertainty in remote Alaska is to say “I’m not sure.” Often. This statement from poker champion Annie Duke1 acknowledges uncertainty and promotes open discussion in the group.
Another useful technique for embracing uncertainty is Roger Atkins’ strategic mindset for avalanche decision making under uncertainty. Begin your trip in remote Alaska with a strategic mindset of Assessment where “There is a high degree of uncertainty about conditions, such as when…entering new terrain….” The operating strategy is to “Select conservative terrain in which to operate confidently while more information is gathered to gain confidence in the hazard assessment.” This means maintaining big margins for safety and making a lot of observations.

Observe Conditions
Observing conditions is the first part of the backcountry cycle. As soon as you get into the mountains you can get your hands on the conditions you forecasted during trip planning. This is called ground truthing. Look for red flags for unstable snow. Test the snowpack with slope tests, feel underfoot, extended column tests, etc. An Observation Worksheet helps learn this process.
The probe is especially useful for learning about the new snowpack in a remote area. Get out your probe as soon as you get there. Feel for snowpack depth and layering. Is there a strong slab over a weak layer? Keep your probe out as you make your first track, probing the layers along the way.

One of the biggest differences about remote Alaska is I don’t have professional avalanche forecasters like Wendy Wagner and Aleph Johnston-Bloom digging a bunch of pits for me. I have to dig the pits myself. In pits, as with the probe, focuss on searching for a deep slab avalanche problem. These are the big and deadly avalanches that are hard to identify without an avalanche forecast. Nobody wants to get surprised by a deep slab.
Forecast Avalanches
The second part of the backcountry cycle is to forecast avalanche danger and problems based on the observations you made. This process is laid out in the pithy paper entitled Conceptual Model of Avalanche Hazard.
The structure of an avalanche problem is defined by its type, location, likelihood and size. From the Conceptual Model of Avalanche Hazard.
One way to distill the Conceptual Model into a usable format, and to learn the process, is with a Forecasting Worksheet. This helps describe the components of each avalanche problem that are present, come up with an overall avalanche danger, and determine what observations will most reduce the uncertainty.
A useful forecasting tool for remote locations is the Dangerator developed by the Canadians. The Dangerator says your starting point when arriving in the remote backcountry is considerable. Considerable means “human-triggered avalanches are likely.” That’s the real deal. Avoid avalanche terrain when you first arrive until you make observations that may reduce uncertainty.
Another problem with a considerable danger rating is this is where uncertainty about triggering an avalanche is often highest. At moderate and considerable you often don’t really know what’s going on in the snowpack and decisions are difficult. On the other hand, decisions are easy at low danger where it probably won’t avalanche. Decisions are also easy at high and extreme where it probably will avalanche.

Build Route Options
The third part of the backcountry cycle, after making observations and forecasting avalanches, is to build route options. Notch back all of your route options during the entire trip to account for uncertainty and lack of rescue resources. Start on simple, non-avalanche terrain for the first day or two as you make observations and assess conditions. As observations reduce uncertainty, you might step out into more aggressive terrain, or your route options may stay mellow and simple the entire trip.
In this photo we have a variety of route options, from this low angle powder slope to steep and committing lines if our danger rating and uncertainty go down.
Add Margins For Safety
The final part of the backcountry cycle is to add margins for safety. These margins are travel techniques to help asure we don’t get caught in an avalanche, and to increase our odds of survival if we do get caught. In remote Alaska these margins need to be bigger than normal to account for high uncertainty and the lack of rescue resources. Rescue won’t be coming any time soon.
We planned our entire trip around getting this glory chute. Halfway up the snow began feeling slabby. In doubt, we turned around. Turning around is my favorite margin for safety. I use it all the time. Everyone in the group knew that we were ready to turn around if things felt at all weird. The chute is still waiting patiently for us to come back for another crack.
The margins of safety we use in everyday backcountry skiing are important such as spreading out, stopping in a safe zone, and spotting our partner. In remote Alaska, other margins also become more important such as starting on small terrain, turning around if in doubt, ski testing before committing to a slope, and slowing down. Habitually using fat margins of safety will save your ass more times that you will every know.
There’s a Time and a Place
Getting into big complex terrain in remote Alaska requires a unique combination of conditions and people. You need to have found low danger after searching everywhere. And your group needs to be in agreement and feeling good about the conditions. Don’t expect this perfect combination on your first trip. You’re on nature’s schedule.
Mike Schmid on the run of dreams. We’d been on numerous trips to remote Alaska to nail this perfect combination of avalanche conditions and group. Every trip had been a wild and memorable adventure into the unknown.
I figure I nail conditions on one out of every five trips. The trick is to enjoy every trip. Those that go on many trips into remote Alaska enjoy the process more than the goal. Learn to enjoy terrain that is low angle and has low consequences. Enjoy camping and the simple life. One trip we flew into remote Alaska and dug for nine days straight, trying to stay afloat in a colossal snowstorm. It took us back to our simple roots of survival: dig, eat, sleep, read, talk, repeat. Boredom is precious these days.
It may seem like I’ve turned backcountry skiing into a laboratory research experiment. You can ignore all of this and just go skiing, and you’ll probably be okay, but it is more sustainable if you have a method to the madness. Avoiding avalanches in remote Alaska is simply learning how to think like nature. We have these skills engrained in our DNA from five billion years of programming. The trick is to slow down and apply those engrained skills to think like the mountains.
