Crown line in Central

Location: Central Gully in Huntington Ravine

Note: This observation is from Thursday, January 28th, 2021

While traveling in Huntington Ravine I noticed what looked to be a small crown line just below the ice (looker’s right) in central gully (see attached image). I climbed towards pinnacle gully to get a closer look. At the small rock bench below central (i.e. before terrain steepens to 40+ deg) there was clearly a crown line in the aforementioned location, and small piles up debris further down the slope. Both the crown line and debris were already being covered up by falling snow and wind loading. There was only one set of ski tracks adjacent to the crown line thus it is difficult to determine whether someone triggered the slide or they also went up to gather observations. Either way, pockets of instability still exist, particularly on steeper slopes where new snow hasn’t bonded well with the old, stubborn, wind slabs. Small sloughs (skier triggered and natural) were observed in lower angle terrain on a variety of aspects in Huntington.

Aspect: E/SE
Elevation: 5,000ft
Slope Angle: 45deg
Type: Soft Slab
