Which emergency signaling techniques work best in snowy conditions?

Visual Signaling in Snow

In snowy conditions, it’s essential to use high-contrast colors to create visual signals that can be seen from a distance. Use brightly colored materials such as orange, yellow, or pink to create a signal. For example, tie a brightly colored shirt or scarf to a tree or a long branch to create a clear visual signal. Aim to create a signal that is at least 6 feet tall and 3 feet wide to maximize visibility.

Audible Signaling in Snow

Snowy conditions can mute sounds, making audible signaling challenging. However, use of mirrors or shiny objects can amplify sound reflections. Create a series of loud, sharp noises by breaking sticks, using a whistle, or banging two rocks together. If you have a whistle, use it to create a loud, piercing sound that can be heard from a distance of up to 1 mile. If you don’t have a whistle, use a piece of metal or a stone to create a similar sound.

Night Signaling in Snow

At night, use high-contrast colors and reflectors to create a signal that can be seen in low-light conditions. Use a light source such as a flashlight or a fire to create a beam of light towards any aircraft or potential rescuers. Aim to create a signal that is at least 3 feet tall and 2 feet wide to maximize visibility. If you have a mirror, use it to reflect light towards any potential rescuers, increasing the signal’s visibility by up to 4 times.
