Avalanche: Turnagain
Location: Seattle Ridge
Normal uptrack, normal amount of people putting themselves in unnecessarily hazardous avalanche paths. In addition to the point release discussed below, we witnessed three snowboarders drop the same cornice onto a steep slope (solar aspect) and ride down at the same time. Second rider on slope triggered a small slab near the top while the first rider was crashing below him. Slab fortunately did not travel far or threaten the lower rider.
Avalanche Details
Snowboard triggered wet point release on a solar aspect. Slide was moving fairly slowly but rider was nearly overtaken by the slide when they cut back underneath of it (not knowing they had triggered it!). Slide was small but could have easily knocked the rider off their feet and then covered them with heavy wet snow. Also, snowboarder's buddy was sitting on his snowmachine in the runout zone.
Observer Comments
Roller balls on all solar aspects around this area.
Weather
Sun, calm winds, warm temperatures.
Snow surface
Wet settled powder at lower elevations and solar aspects, dry powder in alpine and shaded aspects.
Point release just south of Seattle Ridge uptrack.
Tracks and small storm slabs released (by both snowmachines and skiers) below peak 3280 on seattle ridge.
Conditions in large bowl north of uptrack, Glide crack on a solar aspect looming above popular track and meeting spot.
Tincan conditions and tracks. Only notable slide activity (besides glide cracks in the trees) is a crown line east of Todd's run on the far left of the image. Closeup on next image.
Closeup of slide near Todd's Run. appears to be a point release, possibly skier triggered (appears to be a track above, near the top, then again lower on the left next to the crown).
Slope where we witnessed group of 3 on slope at same time. Solar aspect with roller balls below cornices and previous tracks releasing small, loose pockets.
