Observation: Turnagain

Location: Eddies

Route & General Observations

Toured up to top of treeline on Eddies looking to test how the new snow is bonding and for areas with fresh wind transport.

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

Light snow and obscured skies throughout the day. About 1" of snowfall during the day. Winds were calm to light.

Snow surface

Deep soft snow, about 35 cm (14") of settle new snow on top of the old snow surface. Some areas along ridgelines and prominent features had wind effect at upper elevations. Ski quality was high.


We dug pits in 2 different locations around 2000'. The first was wind loaded and I was hoping to find easier propagation where the slab was a little stronger. Total snowpack depth was 165 cm in that location. In our extended column test we had a failure at the interface of the new snow and old snow about 30 cm down (12") we had an ECTN 3, so a failure but with no propagation. After the test I hammered on the column and got a propagating result at the top of the melt freeze crust about 120 cm down (4').

In our second pit the snowpack was more representative with a total depth of 115 cm. In this pit we had a failure 35 cm (14") down at the interface with the old snow surface. This failure propagated about 2/3 of the way across the column (ECT N 15).
