Snowpack: Snow pack depth varied from 140cm to 190cm, deeper as we climbed. No obvious signs of instability on the way up. Resistant planar fracture in compression test with 13 taps. The extended column test also showed a resistant planar fracture but it took 3 moderate loading steps to drive the failure across the column. Both tests fractured on buried surface hoar 60cm down from the surface.
