Went for a tour up Tam Rim Friday. By the time we got above the escalator and to the edge of the playground the wind had noticeably picked up. Blowing mostly from SW to NE. We dug 1 meter down on a NE aspect to check how the storms from the past week were setting up. HS was 145cm. There was ~10cm of wind slab, 20cm newer snow with a slight crust in the middle, then a combination of rounds and funky little breakable crusts for another 35cm with a more stout 1F/P ice layer on top of smaller grain facets to ground.
On both compression tests we had a CTE 20cm down on the interface between the NS and the older storm snow, then CTM 30,40 and 55cm down. They all popped within 1 or 2 medium whacks of each other on the crust layers. See attached pics.
We went back to lower elevation and had fun in the low angle trees.
It will be interesting to see what this warm cycle does to those upper layers..
