Observation: Turnagain

Location: Lynx Creek

Route & General Observations

We rode up Lynx Creek to get our first look at the snowpack in that neck of the woods for the season. We confirmed our suspicions that the snowpack in this corner of our advisory area is thinner and weaker than most of the Turnagain Pass zone. The facets above the Thanksgiving crust were weaker and bigger than what we’ve been seeing elsewhere, and there was 2mm depth hoar at the ground.

This snowpack is likely to produce avalanches once we get a significant load. For now, it is still a possibility but the odds of someone triggering an avalanche are becoming less likely the farther out we move from the last loading event- now over a week ago.

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

It felt good to get out in some warmer weather! Temps were in the low 20's F under mostly cloudy skies. A low level cloud that was hanging in the drainage made for challenging visibility until it lifted later in the afternoon. Winds were calm.

Snow surface

There was 1-1.5' soft snow on top of the thanksgiving crust. Some more exposed terrain features had some evidence of wind loading, but those features were isolated.


The snowpack was thinner and weaker than anything I've seen at Turnagain Pass this season. The layer of facets above the Thanksgiving crust was fist hard with 1 mm facets. The Thanksgiving crust looked similar in structure to most of our other pits- about 6" thick with alternating layers of crusts and facets. The October facet layer on the ground was weaker (fist hardness) with larger grains (2 mm on average) than what we've seen elsewhere on Turnagain Pass. This could be a scary setup when we get our next big storm.
