If you are traveling to the snowy expanse of mountainous terrain, the danger of avalanches underscores the need for preparedness. Most hikers learn how to be  prepared for an avalanche to mitigate the risks and save their lives. From recognizing the avalanche forecast to assessing the terrain before hiking, there are several important preparations that one has to make before navigating the treacherous terrain.

When it comes to taking the right measures to survive an avalanche while skiing or in a car, the most important aspect is having a power source that lets you charge your emergency gear. Jackery Solar Generators are designed so that one can carry them on outdoor adventures, and they can power up to 99% of your emergency appliances.

Understanding Avalanche Facts

An avalanche is a rapid flow of snow down a sloped surface, typically a mountainside. An avalanche is triggered by several factors, like weather conditions, snowpack instability, and even human activities [choosing the wrong skiing location or destroying the landscape]. A typical avalanche occurs when layers of snow accumulate and then suddenly release.

Avalanches can vary in size and speed, ranging from small and slow-moving to large and fast-moving masses of snow. Depending on their size and speed, most avalanches can cause significant destruction to life, property, or anything in their path.

In the United States, avalanches pose a significant risk particularly in regions with mountainous terrain and heavy snowfall, like Utah and Colorado. As per a report by National Geographic, in the mountains of the western United States, there are about 100,000 avalanches every year. In 2023, a total of 30 reported people allegedly died as a result of an avalanche in the United States alone.

Colorado Avalanche

Colorado is known for its Rocky Mountains, which experience its share of avalanches yearly. One of the most devastating Colorado avalanches occurred in March 2019, when the rapid flow of snow struck near Interstate 70 in Summit County. The devastation was so severe that it buried a section of the highway under 20 feet of snow.

The number of avalanches that reportedly occur yearly is based on reports collected by the Colorado Avalanche Center over the last decade. For 2024, Colorado officials have issued several special avalanche advisories because since January 2024, the state has seen about 905 avalanches, and the number may cross 3,600 during the entire season.

Avalanches can be triggered by various factors, both natural and human-induced. However, understanding the primary causes of avalanches can mitigate the risk and avoid going to the avalanche-prone terrain during the skiing season.

Here are some primary causes behind avalanches:

Snowpack Instability

Snowpack instability is one of the primary causes behind a sudden avalanche. This instability occurs due to several factors, like rapid change in temperature, wind-loading, snowfall, or even the presence of weak layers within the entire snowpack. When the bond between different layers of snow is weak, it increases the likelihood of sudden release, which leads to an avalanche.

Weather Conditions

Different weather conditions create different scenarios that lead to an avalanche. Some weather conditions, like heavy snowfall, rapid warming, or rain on snow, can also weaken the snowpack, triggering avalanches. In most cases, heavy snowfall can overload the snowpack and further increase the risk of avalanches.

Terrain Features

As per Colorado avalanche reports, the terrains with steep or convex slopes, gullies, and couloirs are more prone to avalanches than others. These terrains accumulate snow and are prone to loading from wind and snowfall, which makes them more susceptible to sudden avalanches.

Human Activities

Snowboarding, skiing, snowmobiling, and even hiking can often trigger avalanches in recreational areas such as backcountry terrain or ski resorts. When travelers visit these areas without proper knowledge or equipment, they accidentally venture into avalanche-prone terrain.

Natural Triggers

Several natural factors trigger an avalanche. For instance, earthquakes, rockfall, and cornice collapses in several northern states in the United States have destabilized the snowpack, leading to avalanche release.

What Are The Risks of An Avalanche?

From complete disability to death, there are several risks associated with avalanches. Such natural disasters can pose a significant danger to anyone in their path. By understanding the risks and recognizing the signs of an impending avalanche, one can stay safe and prepared when they travel in and around the avalanche-prone terrain.

Some common risks and dangers associated with an avalanche are:

Injury or Fatality

As one can understand, avalanches can cause severe injuries and even fatalities to anyone caught in their paths. According to a report by FEMA, avalanches have reportedly claimed the lives of an average of 28 people each winter season in the United States over the last decade. The sudden force of an avalanche can bury individuals under tons of snow, which leads to trauma, asphyxiation, and death due to hypothermia.

Trauma & Entrapment

Avalanches and similar accidents can result in trauma caused by debris like rocks and trees. Additionally, it becomes difficult for the rescuers to locate and extricate victims in time when they get entrapped multiple feet below because of the avalanche debris.

Snow Immersion Suffocation

If someone gets caught in the path of an avalanche, they get pushed and later buried deep under the snow. During this stage, they get trapped in an air pocket or cavity. However, as the surrounding snow settles, the air supply diminishes, which leads to suffocation despite being buried relatively close to the surface level.


Exposure to cold temperatures while waiting for the rescuers to come and help can lead to hypothermia.  According to the CDC, from 1999 to 2011, 16,911 deaths in the United States were associated with exposure to excessive natural cold. In this death toll count, deaths due to hypothermia caused by an avalanche are significantly higher.

Terrain Hazards

During the avalanche, several environmental debris, like trees and rocks, also downslope. These terrain hazards can also increase the risk of injuries and entrapment. For instance, someone can get entrapped below a huge tree branch that was brought down by an avalanche.

Signs of an Avalanche

There are several other noticeable risks involved with avalanches. However, several important signs can help hikers understand the path and avoid avalanche-prone terrain.

Recent Avalanches

Before planning a hike or Skiing trip, one should observe avalanche activities in the area. Check previous reports from the official government website and avoid going to those places. At the same time, you can also check for debris or fresh avalanche tracks in the terrain. If you find a lot of debris and unstable snow conditions, you can analyze that that particular area is more prone to new avalanches.

Cracking Snow

You can use your skiing equipment to test the snow layers. If you can feel the snow crack or if the parts of it collapse beneath your feet, then you should avoid going forward. Such a feeling of snow crack suggests the presence of weak snow layers that increase the chances of an avalanche in the near future.

Snowpack Instability

Check for the snowpack instability signs, like collapsing snow layers, hollow sounds, the presence of weak layers, and faceted crystals in your terrain path. These signs of instability indicate an increased risk of avalanche activities.

Rapid Change in Weather

Rapid changes in the weather, like sudden rain or snowfall or even rapid warming, can also destabilize the snowpack. These sudden changes in the weather can also increase the likelihood of avalanches.

Wind Loading

The heavy winds can transport snow that accumulates on leeward slopes. The continuation of such wind-transported snow can lead to the formation of thick slabs that also increase the risk of avalanche release in that particular leeward slope.

Here is an easy table to illustrate the risk of an avalanche:

Working Hours = Battery Capacity in Wh * 0.85 / Wattage Consumption of the Appliances

Working Hours = 2042.8Wh * 0.85 / 1160W = 1.4 H.

Note: The total battery capacity of the portable power station is multiplied by 0.85 because some power is lost during the appliances' initial charging.

How do you avoid being caught in an avalanche?

The first step is to check the avalanche forecast in your or the traveling area. The second is to always travel with experienced companions and carry safety gear.

What 3 things do you need for an avalanche to occur?

Three main factors are required for an avalanche to occur: Slope with a steep angle, Snowpack with varying densities of snow, and Triggering factors such as heavy snowfall or rapid warming.

What not to do during an avalanche?

During an avalanche, avoiding actions that could increase your risk of injury or reduce your chances of survival is essential. For instance, you should not attempt to outrun or outski the avalanche. You should always deploy the avalanche airbags or other safety devices before the avalanche comes near your camp.

Should you try to dig yourself out of an avalanche?

No, you should not attempt to dig yourself out if you are stuck in an avalanche. If caught in an avalanche, your chances of survival are higher if you can stay on the surface of the moving snow and create an air pocket around your face. Try to remain calm and conserve energy.
