Loose Dry

- 1–2
A handful of loose dry avalanches have occurred recently with one scrubbing to ground. They are currently limited to specific terrain such as very steep alpine rocky terrain yet enough of a concern if a person is standing below it or gets swept away.

You must keep this basal layer on your radar as triggering is possible in isolated features, such as steep rocky terrain where you find yourself standing on the surface and not wallowing in facets, that's the problem slab.
