Surface crust distribution is variable in its supportiveness; moist snow in the upper snowpack is slow to refreeze. Watch out for areas where a supportive melt-freeze crust hasn't formed.
Where a melt-freeze crust has developed, this layer will be difficult to trigger. With uncertain freezing levels, areas of concern are steep, rocky terrain, where there is no melt-freeze crust.
Recent snow will lose cohesion with even short windows of sun and rising freezing levels. The upper snowpack remains moist in some areas and could release if the melt-freeze crust breaks down.
Recent snow buries a widespread surface crust that becomes more supportive as you gain elevation.
Refrozen and moist snow can be found in the upper snowpack, depending on elevation, which overlies a settled mid-pack.
In the lower snowpack, a persistent weak layer of facets remains a concern where there is no supportive melt-freeze crust.
