(Environment Canada)
SNOWPACK DISCUSSION:
Last weeks storm cycles brought 120cm of snow to the local mountains followed by heavy rains. Widespread small natural avalanches were occurring yesterday as the rain began. The rain, which stopped this morning, has penetrated the storm snow and reduced it down to 70cm. This 70cm of wet snow is sitting on a strong melt freeze crust. Be cautious of wet snow sluffs, especially on South aspects.
Sunrise: 6:40
Sunset: 18:06
The above rating is an assessment of the avalanche conditions as of the posted date. Avalanche hazard is subject to sudden change due to changing weather conditions and variation over terrain. The rating is provided to assist backcountry travelers in making their own educated decision as to whether travel is advisable. Individuals should make their own assessments before travelling into the backcountry.

not on Hollyburn I didn't - the area near the BC Parks trail is a ridge walk and there is little sluffing there.
however, I did see a few other classic avalanche warning signs - pinwheel snowballs rolling off the small summit area of Hollyburn, and the cracks in the snow in the area just above where the cross-country trail ends.
But because that particular area is so well-travelled, and because terrain is low-incline most of the way (except for the final push to the round summit) I estimated the risk near that trail as low.
Now, I wouldn't want to be near the higher incline areas, with no traffic, with lots of wet heavy snow loading.
The Avalanche rating in the North Shore mountains, and Hollyburn's even terrain, enabled me to choose Hollyburn over Seymour or Grouse for today's little escapade.
