Rutschblock Test

Basic test (in many formats) if out on snowpack looking for weak layers. Here you can see how the weak layer shears under pressure, and snow slab on top of the weak layer slips out on weak facets/crust layers:

This one indicates observations of spider web cracks, and below the snowpack on can see how they correspond to the weak layer:

Here is a basic snow profile that one should know if venturing out on avalanche terrain - bring a shovel, do a test:


Avalanche terrain (as a frequency of slope angle release):


Very steep rock slopes shed snow often, however cornices (wind driven) within and above can build and release, so very dangerous and something to watch for:
