Observation: Turnagain
Location: Granddaddy
Skinned up Bertha Creek to the saddle between Granddaddy and Pastoral. Climbed the ridge to the peak and dropped in Granddaddy couloir. Skied out the same track.
Surface snow above tree line is very light. Some wind effect but not quite enough to form a slab. The sun was warm and the sky was mostly clear.
Obvious signs of instability
Observer Comments
Gigantic Glide cracks, as well as glide releases on S face of Cornbiscuit. One glide crack on N face of Lipps. Some small point releases later in the day on southern aspects baking in the sun on Pastoral.
See photos.
Weather
Sky - Few
Wind - Light E/NE
Air Temp - -5 deg C
Snow surface
Below tree line - a breakable melt/freeze crust ~5cm thick
At Tree Line - the crust thinned and eventually disappeared
Above Tree Line - Light density dry snow, wind packed in spatially variable pockets
Snowpack
In alpine elevations the snowpack mostly consisted of ~20cm of light density dry snow on top of a more dense, more moist layer that served as a base. Wind packed pockets had a more dense wind layer on top of the light density snow.
