It was 0°c up to 1700m by 10am with a 5-10cm temperature crust. Above this elevation the crust gradually disappears. Skied up to 2400m on NE aspect with a HS of 300cm+ . Wind affected slightly lower in the path at 2000m. By 4pm, 1700m down to valley bottom was isothermal and almost ski pen to ground. Air temp was +5°c. Managed to cross both rivers in the AM & PM with still a few thin places to cross but it's going to be a bit desperate in the very near future. The day was mostly overcast or broken skies, with some flurries & light winds with moderate gusts from SW. Only recent avalanche activity were some very small dry loose in the alpine out of steep rocky features & steep solar aspects as well as small wet loose on steeper slopes below treeline.
Snow conditions were: Crusty, Heavy, Powder, Wet, Wind affected. Weather conditions were: Cloudy, Warm. We rode: Alpine slopes, Dense trees, Steep slopes. Riding quality was good.
Avalache Conditions: Rapid temperature rise to near zero degrees or wet surface snow.
