In sintesi

The snowpack is not trustworthy at the moment. Use low angle terrain to limit your exposure to avalanches.

    Caution for windslabs on lee aspects in the Alpine and at treeline. Crossloaded terrain should also be treated as suspect.

    This is describing the layer down about 60cm. It is a 10-15cm thick layer of facets. So far failures have occurred within the layer, not at a specific interface.

    In some alpine areas we're seeing the base layers rot out and fail under testing. The trend is unknown on where exactly this is happening. Dig to inspect areas as you approach alpine elevations.

Weather Forecast

The current trend is for increasingly high pressure to approach as the week goes on. With this we'll see no significant precip, stable temps and light winds. Tomorrow will see highs of -9 in the alpine with light southerly winds.

Avalanche Summary

Nothing new today.

Snowpack Summary

The below tree line snow pack is still terrible. 50-60cm of facets makes trail breaking frustratingly difficult and tediously slow. Ground hazards are barely buried.Moving up to treeline, there are three distinct layers/interfaces to watch for. The top 40-60cm is a series of laminated windslabs of varying densities. In some windloaded areas, there may be failures within these slabs. This layer will likely react as one solid layer if initiated. Below that lies the Dec 18th facet layer. In today's trip to Tent Ridge, this interface/layer was very prominent. Tests had a consistent failure down 60cm within this facet layer. Below this lies the third main layer which is made up of the various crusts from earlier this winter. In general it seems to be relatively solid. In the alpine it is similar, except for the additional windslabs on the surface.
