A gourgeous day with little wind and lots of sun sure made it feel warm in the BWRA today.  Recent warming and sun has allowed crust layers to develop on all aspects.  A dusting of snow fell yesterday and was most evident in shaded areas.  Aspects recieving more sun had softened by midafternoon and a cm or so of wet snow had developed at the surface.  Rollerballs were observed releasing from the base of one rocky pillar but not widespread. 

We rode to Koenig Lake and toured up to Latopie Lake with the intention of checking out stability on an E aspect.  We targeted a more shallow area to see if the facet layer at the base of the snowpack would be more reactive there.  We found an area below a small rock outcrop that was 130cm deep and had facets at the ground. Our extended column test was not reactive but our compression tests failed at the interface between the facets and the Jan 26th storm. This indicates that while avalanches may be unlikely, the snowpack structure exists for one given a trigger in the right location.
