Observation: Turnagain

Location: Seattle Ridge

Route & General Observations

Quick trip over to the motorized up-track on Seattle Ridge to take stock of all the carnage of glide avalanche debris. There is significant debris covering the main up-track and riders are taking alternate routes. Even though much of the snowpack has avalanched on this slope (Repeat Offender), there are still cracks and areas that have not yet released. We took a quick look around from the ridge itself and didn’t see any signs on human triggered avalanches. There is only around 8″ of new snow and old tracks are not very well covered up.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Cold (-10 to 0F)
No wind down low and just a light NW breeze on the ridge.

Snow surface

8" of new low density snow from Sunday night/Monday.
Not very wind effected, surprisingly. Old tracks can still be easily seen under the new snow.


We only dug one quick shallow pit to look at the interface between the new and old snow. It was at 2,400' on a northerly aspect above Main Bowl.
No instability seen, just 7-8" of very loose snow over slightly harder old faceted snow. We looked for surface hoar at the interface but could not find any.
If the wind does pick up tomorrow (Thur), there is ample loose snow to drift into slabs.
