    INFORMATION & OBSERVATIONS:

    Avalanche Canada Fund Raiser. Awesome evening!!!

    Surface hoar continues to grow.


    Skiing is quite nice down Blackcomb Bowl Ridge.

    Translucent Cornice, yes that means fragile!!!

    Looks fragile.

    Glide crack on Bushrat.

    Separation in the glide crack.

    Truly amazing how the separation occurs in the snow and pulls apart with some integrity..

    Cornice line after explosive control.

    Cornice debris in the bowl.. Be aware once it starts snowing again and visibility is not ideal.

    Warmth creates melt., cornice gets heavier, begins to cleve, and eventually falls off.

    A very spectacular view.

    Cornices grow on buildings as well.

    Avalanche awareness tour, tours are daily at 12:30, top of the Gondola on Blackcomb.

    Cool clouds at days end on Tuesday.

    Big picture Tuesday afternoon.
