We just finished one of the ACMG Assistant Ski Guides exams
over the last 9 days.
We traveled through the Wapta area on the 7-8, Albert Icefield
on the 10-11, and Rogers Pass on the
12-13.
Here is what we found
Wapta Icefield- Objectives included Mt Gordon, Mt Olive, St
Nick, Mt Balfour. Overall fast alpine travel conditions, with isothermal
conditions at tree line and below in PM. Generally good snowpack
stability with deteriorating conditions from daytime warming.
Albert Icefieds (Southern Selkirks)- Conditions changed over
the two days from spring like conditions, to winter with 15 cm of new snow in
alpine, moist below 6000’. Light to moderate winds from SW creating
some transport at ridgetop and lee features. Stability remained in the
good range (mod- low hazard), deteriorating on solar aspects from daytime
warming/ radiation.
Rogers Pass-
Traveled in Asulkan, Illicillewaet, and Connaught
drainages. New snow accumulations on average of 30 cm with light to
strong SWly winds (location dependant). Soft slabs and lee loading
beginning to occur, moderate trail breaking up to 30 cm. excellent powder
skiing on North aspects above 5500’. New snow overlies variety of
surfaces depending on aspect and elevation, including supportive crust in
alpine, moist snow at treeline, and wet snow below tree line. Stability was
on a decreasing trend with additional snow accumulations and wind transport/
loading.
Overall temperatures in all areas ranged from -5 to
+5. Limited avalanche observations, mostly solar triggered loose snow
avalanches on steep southerly and westerly aspects.
