Snow was amazing! Between 30 and 50 cm of new, very low density snow, depending on aspect & elevation. One thing that surprised us was how stormy it was all day. Vis was pretty low most of the day and it snowed continuously from 8am-6pm. The cars had ~15cm of new snow on them when we returned. Saw evidence of one small slab from the past 24hrs on east side of the ridge, below the cornice in the needle N bowl but otherwise we didn't see any signs of instability anywhere we went or could see, with the poor vis.

Snow conditions were: Deep powder. Weather conditions were: Cold, Stormy, Windy, Cloudy. We rode: Alpine slopes, Mellow slopes, Dense trees, Open trees. We avoided: Steep slopes, Convex slopes. Riding quality was amazing.

Avalache Conditions: 30cm + of new snow, or significant drifitng, or rain in the last 48 hours. Slab avalanches today or yesterday.


Dug a pit on the east slope of Flatiron @ 1780M. 40cm unconsolidated snow sat ontop of 80-90cm of 4 finger density which sat on a crust. Besides the deeply buried crust, there was an interface about 80 cm down in the middle of the 4F snow which is where we got the most energetic results. Results as follows: CTM16sp down 80cm, CTM18rp down 120cm Another quick pit earlier on a S aspect in the same bowl showed very similar snow pack profile and layers but no CT results (CTN) .
