Glaciers are stunning natural formations, thick sheets of ice that can extend for miles and range from a few yards to thousands of feet in thickness. Many adventurous travelers dream of hiking on a glacier, but the reality is far more dangerous than it appears. While glaciers may seem stable and safe for exploration, they actually hide unseen threats beneath their surface.
Take, for example, North America’s popular Athabasca Glacier in Alberta, Canada, where guides often warn solo hikers of hidden hazards like crevasses and icy rivers. One misstep could lead to serious injuries or worse. So, if you plan to hike on a glacier, it’s crucial to hire a guide unless you have extensive training and experience.
Glacier science
Contrary to popular belief, glaciers are not static structures but living, dynamic entities. Maria Intxaustegi, a mountaineering guide, explains that glaciers are constantly shifting, moving, and changing. Tim Patterson, a certified guide, also emphasizes the need for awareness and proper training when navigating glacier terrain.
Glaciers form over centuries as snow compacts into ice. They flow down valleys, changing, growing, and receding in response to factors like temperature and precipitation. However, most glaciers worldwide are retreating due to climate change, altering the landscape and posing risks to explorers.
Beware of sneaky crevasses
One of the most dangerous features of glaciers is crevasses, stress fractures in the ice that can be hidden beneath thin layers of snow. Falling into a crevasse can result in serious injuries or death, making it essential to understand the signs of these hidden hazards.
In addition to crevasses, glaciers can also contain water features like millwells, circular shafts formed by surface water that can lead to under-ice streams. These hidden dangers can change rapidly, posing a significant risk to unsuspecting hikers.
Other hazards
Apart from crevasses and water features, glaciers present other risks such as rockfalls, flooding, and technical terrain. Explorers must be aware of these hazards and take precautions when venturing into glacier-rich environments.
Find your glacier guide
Despite the risks, glacier-based adventures can be rewarding with the help of experienced guides. It’s essential to choose a reputable guide company with certifications and expertise in glacier travel and safety. By exploring glaciers with knowledgeable guides, adventurers can enjoy a safe and educational experience.
