Snowpack Summary
Up to 20 cm of recent snow has buried a plethora of old snow surfaces which consists of wind scoured surfaces, old wind slabs, surface hoar up to 20 mm in sheltered terrain, and/or faceted old snow. Recent moderate winds from all directions is has redistributed some of this new snow on leeward slopes and behind terrain features. Deeper in the snowpack, the mid-December persistent weak facet layer has been more prominent and reactive in the Corbin area than areas closer to Fernie. The layer is generally considered dormant at the moment, but its status may change if we head into a warmer, wetter period next week.
