[MCR] Conditions in Southern Purcells

Subject: [MCR] Conditions in Southern Purcells

I?ve spent the last week guiding at Powder Creek Lodge in the Southern
Purcells, east of Kaslo.

A much anticipated storm beginning March 11 came with strong SW winds and
deposited over 70cm of new snow in the area.  When the skies cleared
Saturday morning we observed the wreckage of an extensive natural
avalanche cycle on Northerly aspects at Alpine and Treeline elevations. 
Numerous slabs were observed from size 1-3.5, some showing impressive
propagations with fracture lines up to 1km wide. Most slabs failed on the
surface hoar layer buried on February 9, now down 80cm.

Saturday while skinning on a flat ridge, we remote triggered a healthy
size 2 on a North aspect at 2300m.  When the sun shone hard mid-day, we
observed three Naturals to size 2 from a cross loaded, west facing Alpine
feature near the lodge.

The upper snowpack is highly complex, with four buried layers of surface
hoar in the top 100cm.  It will take some time for the snowpack to adjust
to the new load.
