Date of Observation: 12/31/2022
Name: Evan Ross
Zone: Northwest Mountains
Route Description: Lower Kebler Pass. Variety of aspects.
Observed avalanche activity: Yes
Avalanches: Few small storm slabs.
Weather: Overcast. Light down-valley winds in the afternoon. Snowing S1 to S2
Snowpack: Quick tour, mostly targeting some NE slopes BTL in lower Elk Creek. Other than a few small storm slabs, nothing notable in the lower Elk Creek area or near the road on Kebler. Traveled on several small test slopes, and near-defined avalanche terrain with no obvious signs of instability.
ENE, 31-degree slope, BTL that does see wind-loading. HS 153. The recent storm interfaces were down about 15cm and 25cm. December 20th was down about 70cm. ECTP 3 on the lower storm interface. ECTN 24 on 12/20. The 12/20 interface was very thin and difficult to see in the pit wall, but still defined 1mm NSF on the card.
