Heavy wind affect in the alpine. Lots of new snow/cross loading. Natural avalanches present that released within the last 24hours. We performed a column test on a SW aspect. failed within 6 wrist taps. Layer failed 45cm down likely on the early December weak layer. Following this we managed to get a result that stepped down to a buried layer around 70cm. The snowpack where we tested was 130cms deep. We stuck to low angle terrain and exited though mostly open trees down. We had just broken tree line when we decided to call it and ride down.

Snow conditions were: Deep powder, Powder, Wind affected. Weather conditions were: Cold, Sunny. We rode: Alpine slopes, Mellow slopes, Open trees, Sunny slopes. We avoided: Convex slopes, Steep slopes. Riding quality was amazing.

Avalache Conditions: Slab avalanches today or yesterday. 30cm + of new snow, or significant drifitng, or rain in the last 48 hours.
