Route & General Observations
Toured up and past the mine. Above the mine the snowpack turns into a pretty upside down setup. About an inch of facets at ground level, followed by an inch or so of crust, followed by another inch of facets and then about four inches of newish snow. The big thing to report though is we had another group touring up the road toward the pass that remote triggered what we are assuming was a wind slab. Hopefully they will report their own observation (forecaster note: avalanche was reported by party and is on observation list) but either way once we regrouped at the cars, they had pictures of a slide that was about 50 ft. wide and about a foot deep. As they toured up the road the slide was on their left side, at the pass proper—so north/northeasterly aspect.
|Trigger||Skier||Avalanche Type||Soft Slab||Aspect||North Northeast|
|Elevation||4000ft||Slope Angle||unknown||Crown Depth||12in|
This is all second hand info so I'll stick to exactly what I was told and saw in the pictures. Our other group said that they heard a whumph from the road, then heard the slide to their left.
