Date of Observation: 03/10/2023
Name: Mark Robbins
Zone: Northwest Mountains
Route Description: amr ziggins, big, east bowl
Observed avalanche activity: Yes
Avalanches: old debris at bottom of big chute under the steep roll on the right hand side. Also old debris at bottom of ziggins, I skied in the trees so didn’t identify where it had come from. Maybe from the right handrail of the ziggins gully?
No storm instabilities on the first two laps. On the last lap around 3:30 things seemed to be reaching a bit of a tipping point, the storm snow sluffing more actively with some clean fractures, tho no real propagation
Weather: warm and wet. 3-4 inches of heavy snow when I arrived at 1, another solid 3 inches on the sled 3 hours later. Calm throughout the amr tenure, some gusts on the ridge
Snowpack:
