GUIDE(S): JSJ
DATE: 1/13/15
ACTIVITY: BC Ski
LOCATION: Coney’s
ELEVATION: 9000′ – 10,800′
ASPECT: N-E-SE

WEATHER: Overcast through most of day. Snowing S1 with periods of S3. Calm winds.

SNOWPACK/AVALANCHE OBS: 20cm storm snow with no wind. Preserved surface hoar layer found below the new snow but finding it non-reactive to quick informal stability tests. An instability was found in the top 5-10cm of the snowpack at what was seeming to be a slight density change in the recent storm snow, as it got heavier with rising daytime temps during the storm today. Minimal problem now…worth re-visiting at it gets buried deeper. Triggered 2 small (D1) loose snow slides on steep low elevation terrain features with convex rollovers, as expected. No other instabilities seen.
