More detailed information about the snowpack: 

Headed up the Williams Lake Trail to get access to North aspects above 11,000' . Believe it or not we still do have snow in mountains.  Any continuous snow is still confined to North aspects mostly above 11,000'.  Near treeline snowdepths vary from 2 to 16" of mostly cohession-less facets.  Other aspects are back to bare ground with two weeks of high pressure really doing a number on our snow.  Above treeline, we have snow from earlier storms that vary in depth greatly due to previous wind events.  Overall, the snowpack is thin, variable and weak with previous slabs deteriorating into facets.  In crossloaded gullies we were able to find a supportable slab on top of facets.  With a potential storm approaching Tuesday Night into Wednesday, it'll be important to pay attention to where there snow is currently as these slopes will present the most problems going forward.

Photo 3: Crossloaded gully with bare ground quickly going to 2 to 4' deep.

Photo 4: Cohession-less facets on a steep convexity that run like water.
