Avalanche Details

Skied southern aspect from Tincan common, observed poor bonding of new snow to old snow pits on the way up but did not note any propagation on ski cuts on west-facing aspects. Skied 35 degree + roller on southern aspect towards the end of the line and the new snow in the past 24 hrs failed on the underlying sun crust. Skier was able to ski off the avalanche and was not caught or carried. We made the mistake of attributing ski cuts on west-facing aspects to more southernly aspects that have been more sun affected and had a harder bed surface.
