Rode Cowboy Ridge for the past two days! So beautiful and quiet! Great-to-incredible snow depending on the run. A touch wind affected at the top but the trees were full on blower! Convex rolls released some small slabs yesterday that didn't run far, But today was more stable. Did 4 laps on Friday and slacked today with 3 laps as Flute sucked us in for an early lap. Headlamp exits via Singing Pass which is in excellent condition. Thierry Keable could WB do something about that deadfall and remaining creek crossings to enhance the customer experience? :)

With a little bit of time to spare between separate work obligations, I went for a quick tour up Seymour. I left the truck at around 2.30pm, and toured up to Brockton Peak. I was planning on doing a full snow pit in the area, but ran out of time. Before I packed it up, I did a compression test. Foot pen about 90 cm, surface temps about -3, and -4 at about 40cm down. I got CTE5 down 32 (the block fell apart when I picked it up), and a CTH23 down 90 (much more consolidated). There was also a hard crust down at about 105, which I wanted to test but didn't have time. I turned around at 3.45. When I got back to the truck at around 6.30, another 10-15 had fallen. Be careful out there, especially in light of other observations people have made. Many BC users out there going past Brockton, I can only hope they all have avy training/experience.

    Light flurries with a thin cloud cover.

    Saturday Afternoon.

    Snowmaking--6 Million gallons consumption in 24 hrs, 104,000,000 gallons as of yesterday.

    Icicles were once snow flakes!!

    They get pretty pointy.
