NoObservations
Good condition today, while very cold. Artist point saw lot of snow transport, but switched direction today. Snow in dog chute was wind transported and was worst than other areas skied today. Not much sign of reaction while entering the line, but once at 4900 ft convexity, reaction was observable and small human triggered avalanche happened below. On the way in, did pole feel thicker windslab (12inch) with no sign of reactivity while skinning.
