Location: Tenderfoot

Route & General Observations

Toured up to treeline on Tenderfoot to get an updated look at the snowpack in Summit Lake area.

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

Temps in the twenties and calm to light winds. Mostly cloudy but with decent visibility.

Snow surface

Soft snow on the surface with 3-5 mm surface hoar on top.


The snowpack at lower elevations is very weak. We stopped to investigate an old avalanche and sunk to the ground when we stepped out of our skis. Total snow height at 2000' on a NW aspect was 100 cm. Our compression test failed on isolation on a very concerning weak layer of depth hoar on the ground. There were also 3 layers of surface hoar in the upper 50 cm of the snowpack. The avalanche had failed on a large layer of surface hoar down 40 cm from the surface. Surprisingly only 1 our of 4 ECTs propagated.
