Avalanche Engineers

A little bit of snow science in the lab and in the field. The engineers are looking at a particular type of weak layer formed by surface hoar (aka frost). It forms in anticyclonic conditions where there is a strong temperature gradient on the surface of the snow. A thin weak layer it features high spatial variability making it hard to detect; as a consequence it probably takes out more snow professionals than any other weak layer.

La belle reprise

A little afternoon tour to test the fresh snow and gear. There is no base in the snow pack below 1700 meters but still some rocks below 1900 meters. The snow was hardened by wind at the col de Oudis and some other exposed spots.
