After last weekends double whammy of D3 Deep persistent avalanches, high up on the crest's leeward slope. We havent seen anymore surface evidence of reactivity from this buried layer. A couple of days of heavy snow and wind, should either get more reactivity out of this layer or pleasantly (possibly) put it to bed. We weren't able to get high into the alpine (above tree line) yesterday during the storm, but with the amount of SWE and wind. The slopes are loaded.
We will be giving the suspected slopes a wide berth until we know better how they will respond with the new snowload.
