Bow Summit snowpack

80 cm deep, weak snowpack at Bow Summit treeline. Buried crust and surface hoar in the middle of the snowpack with facets and depth hoar below. CT 11 taps fails Sudden Collapse just below the crust, then the depth hoar below crumbles away while trying to do tests. Skiing was nice on the surface with 10 cm soft pow, but felt very tentative with all of the rocks around. Very careful skiing.
