All this recent snowfall is likely to be reactive to human traffic.The mid-January layer of surface hoar is buried around 50 to 80 cm. The surface hoar is found on shaded and sheltered slopes and is most prominent between 1600 m and 1900 m but has been found up to 2200 m.The middle of the snowpack is generally consolidated.
