We went to the Telkwa Mountains today to do a little maintenance on the weather station and to see what the previous outflow winds have done to the area. We saw no new avalanches. The previous strong NE (outflow) winds have really scoured any exposed features leaving lots of bare ground and hard surfaces. In sheltered areas the old snow is faceting due to the cold temps and there were pockets of reasonable snow. We found the total height of snow to be very variable, at the top of treeline it is anywhere from exposed ground to 150cm. We completed some snowpack tests in a profile on an E aspect at 1650m. We had a propagating Extended Column Test(ECT) result in hard taps 45cm down on a layer of small facets. Above these facets is a thick layer of knife hard snow. The hard older snow is acting as a strong bridging layer but we will still be tracking this facet layer below, especially with new load coming this weekend. Temperatures have warmed slightly, to -22, which still made for painful bare handed working.
