Understanding Turnagain Pass Avalanche Terrain

Nestled in the Chugach Mountains, Turnagain Pass boasts over 1,800 acres of terrain, with runs stretching from 1,000 to 3,000 vertical feet. The area is characterized by steep, open slopes, chutes, and cliffs, with elevations ranging from 1,000 to 2,800 feet. This diverse terrain makes it an enticing playground for thrill-seekers, but it also presents significant avalanche risks.

Common Avalanche Terrain at Turnagain Pass

1. 1. Steep Slopes: Many runs at Turnagain Pass feature slopes angled 30 degrees or more, which are prime avalanche territory.
2. 2. Persistent Slabs: These are weak layers within the snowpack that can remain unstable for days or even weeks. They're common in the Turnagain Pass avalanche zone.
3. 3. Convex Rollovers: These features can trigger avalanches due to increased stress on the snowpack.
4. 4. Cliffs and Gullies: These features can funnel and amplify avalanches, making them even more dangerous.

Turnagain Pass Avalanche History

To truly grasp the Turnagain Pass avalanche risks, let's take a look at the area's history. On January 19, 2012, a massive Turnagain Pass avalanche occurred, burying two skiers under 10-15 feet of snow. This tragic event serves as a grim reminder of the area's potential dangers.

Assessing Avalanche Risk at Turnagain Pass

Before heading out, check the Alaska Avalanche Information Center's (AAIC) daily forecast for Turnagain Pass. The AAIC uses a color-coded system to rate avalanche danger:

- Green: Low - Blue: Moderate - Purple: Considerable - Red: High - Black: Extreme

Even if the forecast is green, always be prepared for changing conditions. Avalanche danger can increase rapidly due to factors like new snow, wind, or warming temperatures.

Turnagain Pass Avalanche Safety: Essential Gear and Skills

Gear

1. 1. Avalanche Transceiver (Beacon): This device emits a signal that can be picked up by other transceivers. It's crucial for locating buried victims.
2. 2. Avalanche Probe: A collapsible pole used to poke into the snow to locate a buried person.
3. 3. Avalanche Shovel: Essential for digging out buried victims. Consider a lightweight, aluminum shovel designed for backcountry use.
4. 4. Avalanche Airbag: An inflatable device that can help you stay afloat in an avalanche. While not a replacement for proper training and decision-making, it can increase your chances of survival.

Skills

1. 1. Avalanche Awareness: Educate yourself about avalanche risks, terrain, and weather conditions. Consider taking an avalanche safety course.
2. 2. Travel Techniques: Learn how to travel in avalanche terrain, including how to traverse slopes, travel one at a time, and avoid high-risk areas.
3. 3. Snow Pit Analysis: Learn how to dig snow pits to assess the stability of the snowpack. This involves using tools like a snow saw and a ruler to measure layer thickness and perform stability tests.
4. 4. Avalanche Rescue: Practice using your beacon, probe, and shovel to locate and dig out buried victims. Time is of the essence in an avalanche rescue – the chance of survival decreases significantly after 15 minutes.

Turnagain Pass Avalanche Safety: Red Flags and No-Go Zones

Even with the best gear and training, there are times when it's simply not worth the risk. Here are some red flags and no-go zones to watch out for:

- Recent Avalanche Activity: If you see fresh avalanche debris or recent avalanche activity, it's a sign that conditions are unstable. - Steep Slopes: Avoid slopes angled 30 degrees or more, especially if they're convex or have other signs of instability. - Terrain Traps: Steer clear of areas where an avalanche could carry you into a dangerous position, like a gully or cliff band. - High-Avalanche-Risk Terrain: Areas like the Seattle Ridge at Turnagain Pass are known for their high avalanche risk. Only venture into these areas when conditions are stable, and you have the necessary skills and equipment.

What to Do If an Avalanche Strikes

If you're caught in an avalanche, try to:

- Swim: Move your arms and legs to stay afloat and try to reach the surface. - Roll: If you can't swim, try to roll to create an air pocket around your face. - Prepare for Impact: If you can't avoid it, tuck your body to protect your head and neck.

Once the avalanche stops, try to:

- Create an Air Pocket: Dig a small cave in the snow to create a pocket of air. - Stay Calm: Panicking can lead to hyperventilation, which can use up your air supply more quickly. - Stay Warm: Generate heat by moving your body and staying calm.

If you witness an avalanche, immediately call for help and start a rescue. Every second counts, so don't waste time – dig, probe, and use your beacon to locate the victim.

Turnagain Pass Avalanche Safety: Stay Informed and Make Good Decisions

The key to staying safe in Turnagain Pass is to stay informed about conditions, make good decisions, and always be prepared. Here are some final tips:

- Check Conditions Daily: Even if you checked the forecast the night before, conditions can change rapidly. Always check the latest forecast before heading out. - Communicate: Let someone know where you're going and when you expect to return. Carry a communication device, like a satellite communicator or personal locator beacon, in case of emergencies. - Travel with a Partner: Always ski or ride with a partner, and stay together. If one person gets caught in an avalanche, the other can initiate a rescue. - Be Humble: Remember that even the most experienced backcountry users can make mistakes. Stay within your limits and don't be afraid to turn back if conditions aren't right.
