I spent the past 6 days on the Wapta, based out of Bow Hut with Grant Meekins 
and 11 Mountain Skills Semester students. We toured and climbed Mt.Olive, 
Mt.Gordon, the "little Crowfoot" area and Mt.Rhonda. Though it is still quite 
early in the season for the Wapta, we found reasonable conditions for ski 
mountaineering.

During the week we had temperatures from -12 to -2, winds were generally 
moderate from the west and southwest, and we received 30cm of snow (mainly 
earlier in the week). 

Earlier in the week we saw several loose snow avalanches in steep, un-skiable 
terrain on Northeast aspects. The most notable avalanche of the week was a 
natural, slab avalanche size 2.5 that occurred on the East face of Saint 
Nicholas peak. This happened during the day on Nov 13, it was triggered by wind 
loading and failed to the ground. This avalanche initiated in skiable terrain 
around 38 degrees.

The coverage on the glacier was extremely variable. We spent a lot of time with 
the rope on, chose conservative routes and probed a lot. The high points, or 
crests of the convex rolls had as little as 60cm, more sheltered/wind loaded 
features had a much as 170cm. There were even small sections of bare ice! 
Definitely not the time of year to be wandering around unroped without careful 
evaluation with the rope on, and plenty of probing to be certain!

On the ski out today we found supportive snow all the way back to the car, with 
the main theme being shallow snowpack and buried hazards! Lots of slow skiing 
and many scratches to the ski bases. There are still some small sections of 
open water in the long canyon, but easily negotiated. It seemed like an obvious 
choice not to ski across the thin skin of ice that is now on Bow Lake.

Our primary concerns throughout the week were:
-Windslabs on North to East aspects in the alpine, especially steep terrain 
near ridge crests.
-Variable coverage on the glaciers.
-Buried early season hazards.

All in all, it is REALLY early  up on the Wapta, but worth the trip if you are 
willing to pull back on the reigns and use good judgement.
