"Plowed Friday afternoon for 3 hours. ~8-10 cm at parking lot."

"Spent with Joe and [Thursday] with Christian looking around the Hankin area to make sure everything was all right. Photos [above] aren't high quality but you can see clearly that Christian was looking hard for blowdowns, hazards and anything unusual that may not be covered in our agreement with RSTBC. Lots of traffic in the Run 8 and Run 8A area. This must be taking pressure off Runs 1, 2, and 3. Good to spread folks out. We finished the day with a run down HC3, kicking out small wind slabs as we went. Pretty sure it was good skiing but the light was so flat we just had to stay focused on keeping our knees out of our teeth.

My internet has been down for a couple of days so no real-time updates. Monday plowed for 4 hours 20-25 cm at parking lot. Wednesday plowed for 6 hours (had to widen out road) 15-20 cm at parking lot. Looks like more snow on the way today and tomorrow so will probably head up Friday night to ensure things are good for the weekend.

"Headed out with Joe yesterday and got a good start on clearing blowdown. Where it was required we bucked and hauled all debris off the run. For tree that were sunk in the snowpack we bucked and limbed but left debris on the run. One more snowfall and you will be able to ski over this. Up-track D is clear (as far as Run 4), Run 4 is clear and Run 6 is clear.
Photos of surface hoar indicate full heads up if new snow falls on this.

"Heres my take on surface hoar. May be interesting to put this on web-site but check my facts. If you don't check my facts we may get some interesting feedback going that will leave everyone enlightened (hopefully).
Surface Hoar: Beautiful, Fun and Spooky
During clear, sunny weather the layer of air above the snowpack warms during the day and holds moisture in the form of vapour. As temperatures drop (late in the day and overnight) the vapour sublimates
(Goes from a vapour to a solid directly - no liquid stage) and forms a point on the snowpack. As this process continues more points attach to the start of the surface hoar and eventually build the feather like flakes we are familiar with. While surface hoar resists change (no tendency to round out and bond) it is easily effected by wind. If undisturbed surface hoar becomes buried by subsequent snowfall it becomes a layer of weakness within the snowpack.
On the surface this crystal is a delight. It sparkles and skiing through deep layers of large crystals produces a tinkly/swishing noise.
With new snow in the forecast keep a heads up for pockets of buried surface hoar. All conditions provide us with great opportunities to learn. Travel safe and enjoy this next weather cycle.

Note from Admin: As stated above, check your facts. Here are a couple of references to get you started (but seriously, don't take our word for it, look into it yourself!):
- The Avalanche Handbook By David McClung, Peter A. Schaerer (pg 49)
- (US) Forest Service National Avalance Center
-The Canadian Avalanche Centres Report Glossary:
Crystals, often shaped like feathers, spikes or wedges, that grow upward from the snow surface when air just above the snow surface is cooled to the dew point. The winter equivalent of dew. Surface hoar grows most often when the wind is calm or light on cold relatively clear nights. These crystals can also grow during the day on shady slopes. Once buried, layers of surface hoar are slow to gain strength, sometimes persisting for a month or more as potential failure planes for slab avalanches.
