In Resorts

Without vision due to fog, people cannot see their surrounding and even sometimes the snow surface. In these causes, it easy for people to become lost. Furthermore, if snowboarders and skiers are unable to see the snow surface, they must rely on their instinct and general feel of the ground to move around. Fortunately, resorts block off dangerous areas like cliffs and drops. Moreover, since it is a resort, there are regular patrols that you can call and lookout for. Therefore, though it may be a bit frightening, being stuck with limited visibility in a resort presents little harm.

In the Backcountry 

Unlike resorts, the backcountry is more unregulated and there are no indicators for hazardous areas.  Furthermore, there are far fewer people in the backcountries. This means that if someone were to be injured, it would be far more difficult to find someone for help and rescue. As such, being stuck with limited visibility in the backcountry is far more dangerous than being stuck in a resort with limit visibility. It is recommended to stay put and not move in these conditions. It is good to note that ice and snow can form on you if you remain put which does not present itself as a danger, but it can melt and leave you wet and cold. Therefore, if you are planning to go backcountry skiing, it would be in your best interest to wear waterproof clothing.
