Lo esencial
Though the snowpack is mainly in the grips of daily spring temperature swings, a recent large avalanche failing on basal weaknesses on Mt Blackiston is a good reminder that winter remains on high north faces.

Deep layers are still responsive to large triggers (think cornices or rain) on high north faces. Though triggering this layer is unlikely, it's not impossible as evidenced by a large avalanche on Mt. Blackiston last week.

Snowpack Summary
In most areas we are seeing a typical spring snowpack with crusts breaking down in the heat of the day. The exception is high North facing terrain where temperatures have stayed cold and a winter snowpack remains, with facets continuing to linger at the base. The midpack is generally well settled.
Avalanche Summary
Forecaster observed a large avalanche on a high north facing bowl on Mount Blackiston that occurred sometime in the last week. It was triggered by cornice fall, and ran on basal weaknesses. Otherwise, no recent avalanches were observed.
