[MCR] Mt Athabasca, August 23, 2015

[Public Mountain Conditions Report]

I guided an ascent of Mt Athabasca up and down the AA Col on August 23.

The recent snowfall accumulation of approximately 30 cm has made the 
rubble on the AA Col route less tedious, but has also formed windslabs 
on lee features. Six people who climbed the Silverhorn on Aug 23 
triggered a slab and were carried down 30 metres. They were fortunate 
they didn't go further than that. On the same day, a party of four 
turned back from the Ramp route on Mt Athabasca when they encountered 
windslab. Furthermore, a size 2 slab has cut out of the steep ice face 
below the AA Col next to Mt Andromeda.

Steep ice routes on lee features should be avoided for a while.
