Comments
Today we rode Allan Creek. Visibility was low due to flat light making for difficult travel. It was snowing lightly through the day. We observed many recent avalanches ranging from size 1 to 3. All appeared to be sledder triggered on North-East facing aspects at and around 1900-2600m.
Our group tested a North-East facing convex role at 2300m and were able to trigger a size 1. (Refer to second photo) We completed a fracture line profile on the crown and found it had failed on 10mm surface hoar down 65cm. A compression test of the fracture line failed upon isolation on the same layer. We suspect this is the same layer failing as the other avalanches seen today.
Today riding conditions were great but we did our best to avoid all steep slopes and convexities. It appears that windslabs/ stormslabs on all North-East facing slopes are very touchy to human triggering.
