There’s a nice track across the Neve. Didn’t seem like the big path off the gargoyles has slid yet so it made for good skiing. The lake isn’t firm enough to skate yet so that’s a bummer. The Barrier is in excellent shape with a skis-on creek crossing and easy bootpack to the trail. Skied to inside 1km of the trailhead with a few bunny hops and no damage.
Big G looked great. NF of Dalton Dome looks well plastered. Suspect the Hunt-Kelly is coming into shape.

Trip report from Watersprite lake this past weekend.
Update on conditions: Road was bare in sun exposed sections but extremely icy in the shade up to the plant... past the plant conditions were a mix of slush, rock and ice with variable coverage. Chains were used from the 6km marker onwards.
As expected, at the trailhead the snow was crusty friday AM due to rain likely falling thursday night there, and as anticipated by about 1000m elevation it turned to ~10-15cm of fresh snowfall. This snow remained nice and soft until saturday afternoon when the sun blasted and every south facing slope began point releasing and pinwheeling everywhere (even above 1600m), and with that the snow got really heavy and wet. We avoided everything south facing from then on, and heard lots of snowfalls off of cliffs around the hut as we hung out in the afternoon.
Sunday in the northerly aspects on some lines below the hut were still decent but the snow was definitely gaining weight.
All in all, a rapid turn to spring conditions... |
