How I Stay Alive in Avalanche Terrain: A Skier's Safety Walkthrough

Imagine you're standing at the top of a pristine, powder-filled bowl. The sun is out, the snow is perfect, and you're about to drop in. But you checked the avalanche forecast this morning, and it said 'Considerable' for the alpine. Do you still go? I've stood in that spot more times than I can count, and I've made the call to ski it, and I've made the call to turn around. This article is for the skier who wants to enjoy the backcountry but doesn't want to die doing it. I'm not going to preach total avoidance—that's unrealistic. Instead, I'll walk you through my personal safety checklist, step by step, so you can make your own smart decisions. Because the numbers are clear: U.S. avalanche fatalities have hovered around 25 to 30 per year since 1995, even as backcountry use exploded (Avalanche fatality trends). That's not because we're getting safer—it's because we're getting better at managing risk. Here's how I do it.

1. Know the Danger Scale Cold

The North American Public Avalanche Danger Scale is my first tool. It has five levels: Low, Moderate, Considerable, High, and Extreme. But the key is that danger doesn't increase linearly—it increases exponentially between levels (Avalanche danger scale). That means the jump from Moderate to Considerable is much bigger than you'd think. At Considerable, natural avalanches are possible and human-triggered ones are likely. That's not a day to be messing around in steep, open bowls. At High, travel in avalanche terrain is not recommended, and at Extreme, all avalanche terrain should be avoided—period. Parks Canada goes further: they strongly recommend the general public avoid areas rated High or Extreme, and if you do go, stick to simple terrain or stay within resort boundaries (Parks Canada). I take that seriously. If the forecast says High, I'm skiing groomers or staying home. It's not worth it.

2. Check the Forecast for Your Specific Elevation

The danger rating isn't one number for the whole mountain. It's given for three distinct elevation bands (Avalanche danger scale). So I always check the forecast for the exact elevation I plan to ski. A 'Moderate' at treeline might be 'Considerable' above treeline. That's a huge difference. For example, if I'm planning to ski a line at 10,000 feet, I don't care about the rating at 7,000 feet. I need to know what's happening up high. I use avalanche.org, which pulls together data from professional forecast centers across the U.S. (Avalanche.org education). It's my go-to because it's real-time and reliable.

3. Understand That 'Considerable' Is the Killer

Here's where I get opinionated: 'Considerable' is the most dangerous rating for backcountry skiers. It's not Extreme, so people think it's okay. But at Considerable, human-triggered avalanches are likely. That means you can trigger one, and so can your buddy. The problem is that it's not always obvious where the danger is. You might ski a safe line all morning, then hit one slope that's just right (wrong?) and it slides. I've seen it happen. That's why I never ski 'Considerable' terrain without being extra careful: I pick lower-angle slopes, avoid convexities, and always have my rescue gear ready. And I always remember that the danger scale is based on likelihood, size, and distribution of avalanches (Avalanche danger scale). At Considerable, the distribution can be spotty—so you might think you're safe when you're not.

4. Carry the Right Gear and Know How to Use It

If you're going into the backcountry, you need a beacon, shovel, and probe—and you need to practice with them. The International Commission for Alpine Rescue (ICAR) harmonized the international frequency for rescue beacons in 1989, fixing it at 457 kHz (ICAR avalanche rescue). That means any modern beacon works with any other. But having gear isn't enough. You need to know how to use it fast. In an avalanche, time is critical. ICAR's stats show that in the two decades before 2004, an average of 106 people died each year in Alpine countries, and 138 when North America was added (ICAR avalanche rescue). Most were backcountry touring. So I practice beacon searches in the parking lot before every tour. It takes 10 minutes, and it could save your partner's life.

5. Watch Out for Tree Wells—They're Not Just an Avalanche Problem

Even if you're not in avalanche terrain, you can die in deep snow. Snow immersion suffocation (SIS) is when you fall into a tree well or deep unconsolidated snow and get immobilized, unable to breathe (NSAA tree well safety). These accidents happen in-bounds, too. In the 2024/25 season, snow immersion incidents accounted for roughly ten percent of ski-area fatalities (NSAA fatal incident fact sheet). That's a significant chunk. So when I'm skiing in trees, especially after a big dump, I stay close to my partners and never ski alone. If I see a deep hole around a tree, I avoid it. It's that simple.

What Can Go Wrong: The 'It Won't Happen to Me' Trap

Here's the warning: the most dangerous thing in the backcountry is your own ego. You think you're a good skier, so you can handle it. But avalanches don't care how good you are. The stats show that most avalanche victims are experienced backcountry users. And the danger is real: from the mid-1970s to early 1990s, U.S. avalanche deaths leveled off at 13 to 16 per year, but since 1995 they've stayed around 25 to 30 (Avalanche fatality trends). That's not a decrease—it's a plateau, despite an estimated 8-fold increase in backcountry use. If the fatality rate had stayed constant, we'd see over 200 deaths a year. So we're actually doing better, but the risk is still there. Don't let your guard down.

What I'd Actually Do

Here's my concrete advice: If the avalanche forecast is Considerable or higher, I don't ski any slope over 30 degrees in the backcountry. Period. I might still ski trees at lower angles, or I might stay in-bounds. And I always carry my beacon, shovel, and probe, even for a short tour. I also check the forecast every single morning, even if I'm just going to the resort—because I might decide to duck a rope or hike a ridge. And I always ski with a partner who has the same gear and the same mindset. That's what's kept me alive for decades, and it's what I recommend to anyone who wants to enjoy the backcountry without becoming a statistic.
