Evidence of a natural cycle from the day before. Size 1 to size 2. Dug a quick pit on a north aspect at 1990m. HS 160cm, ECTN 27 down 55cm. HST has formed a soft slab and appeared to be sitting on surface hoar at lower elevations. As we skied down towards BTL we could feel the slab stiffing up. Was able to trigger small pillows and convexities at lower elevation. Snowing all day & about 10cm accumulated on our truck when we got down. Very minimal cracking and no whumphing on the tour up.
Snow conditions were: Deep powder, Powder. Weather conditions were: Stormy. We rode: Mellow slopes, Open trees. We avoided: Alpine slopes, Steep slopes, Convex slopes. Riding quality was amazing.
Avalache Conditions: 30cm + of new snow, or significant drifitng, or rain in the last 48 hours. Slab avalanches today or yesterday.
