Macdonald West shoulder

We rode Mac Donald west shoulder on the 27th. We could observe a soft & thin wind slab on our way up. This slab was easy releasable by a ski cut on small convex and we had light wind for our time out there. We start skiing from 200m from the shoulder. Where we did a CT test. Results at TL : CTE1 (SP) down 10cm & CTH29 (SP) down 55cm. The soft wind slab was stable on our way down. We did not observe any cracking around our tracks or concerning sluffing. Definitely cold snow, it was hard to pick up speed and we could feel a bit of resistance from the wind slab at TL but still good riding quality.
