Route & General Observations

It only takes a matter of hours for the bed surface of a new glide avalanche to melt down to the dirt if it’s facing the sun. There is typically a small amount of snow left on the bed surface from these types of avalanches, giving the bed surface a ‘lighter’ look. If sitting in direct sun, the snow can melt in as little as 1-2 hours! Hence, you know that the avalanche is very recent and a blinking sign to avoid travel under glide cracks.

*If there is no direct sun or warm temperatures to melt the bed surface, it can take much longer and is at the whim of the current weather – making timing much more difficult to determine.
