Snowpack

Instability Comment
<p>uneven snow cover, exposed brush and rocks still an issue, but the real danger is still buried with slowly strengthening bridge over the top that is unreliable. No new activity was noted, but last storm came in warm windy and wet, and bonded well to last little storm, mostly comprising the total snow pack in a lot of areas. High north that held snow now has deceptively strong pack over the top</p> <p>lots of transport has created the usual cornices and while not widespread, were still sensitive today </p>

Strengthening bridge from upper snowpack and wind packed sections still overlies demons that will be slow to heal.  Meager storms only complicate the picture, but the nagging fact remains.  We have a shallow snowpack with buried facets and persistent slabs will be harder to trigger, but step on the weak/ sweet spot, and these things could propagate huge distances.  We had three different collapses today, one that really thundered when Steve stepped onto a little more windward tiny sub ridge near some bushes, so needless to say, we stayed off and out from underneath threats, giving them a wide berth.  I was pleasantly surprised to find spongy firm conditions that made for fast fun turns on low ankle more protected areas, but with 14"-16" totals, lots of slalom gates/bushes/weeds to negotiate.  Access is still an issue especially for machines, lots of deadfall traps, rocks still exposed, etc, and getting around is limited to higher terrain and leeward sides.
