Quick Answer
In mountainous terrain, the best flare colors for signaling are high-visibility orange and red, as they can be seen from a distance. These colors are visible from 10 to 20 miles away, making them ideal for long-distance signaling. They are also effective in low-light conditions.
Choosing the Right Flare Color
When selecting a flare for signaling in mountainous terrain, it’s essential to choose a color that can be seen from a distance. Orange and red flares are the most effective colors for long-distance signaling due to their high visibility. These colors are also more visible in low-light conditions, making them ideal for signaling during dawn, dusk, or night.
Understanding Flare Visibility
The visibility of a flare is determined by its color, intensity, and duration. Orange and red flares are visible from 10 to 20 miles away, while green and yellow flares are only visible from 5 to 10 miles away. When signaling in mountainous terrain, it’s crucial to choose a flare that can be seen from a distance to increase your chances of being rescued.
Selecting the Right Type of Flare
There are two main types of flares: pyrotechnic and non-pyrotechnic. Pyrotechnic flares burn for 30 seconds to 2 minutes and are visible from 10 to 20 miles away. Non-pyrotechnic flares, such as LED flares, burn for 6 to 24 hours and are visible from 1 to 5 miles away. When signaling in mountainous terrain, pyrotechnic flares are the most effective choice due to their high visibility and duration.
