Alaska Pacific University Snow Science 1 class spent Friday snow geeking at Turnagain Pass.
Route: Tincan common uptrack 1000 ft to 2000 ft.
Weather: Nice sunny day with spring like temperatures and no wind.
Signs of instability: None observed during the tour, but later in the day you could see snowball effect
of warming air temps on sunny aspects.
Surface conditions: Dusting of almost intact low density snow from Wednesday sitting on late
February crust. Surface hoar was growing on the top of snowpack on all the elevations we travelled.
Beautiful large triangle formations, see photos attached.
1700′, S aspect, HS 100cm.
We did not find near surface facets on late Jan melt freeze layer in our pits.
Interestingly, weakest layer was wet facets at the base of the snowpack.
CTV, CT10, CT11 all SC at the ground.
ECTX, PST no failure.
