Snowpack Summary
A thin layer of new snow is sitting on windslabs in the alpine and at treeline and above a well settled 40 cm of snow. A crust is present on S facing slopes. A surface hoar layer is found under the top 40 cm and is reactive especially below 1500 m. in sheltered areas. This weak layer is becoming less of a concern for the professional but still produces a variety of test results. The distribution of this weak is patchy, but where it exist, it may be triggered with the weight of a person or snowmobile. A strong mid-pack overlies a weak facet/crust layer near the base of the snowpack, which is now considered inactive.
