Snowpit Observations
More detailed information about the snowpack: 

Toured above Mammoth Rock to top of Sherwin Ridge. New snow totals ranged from 5cm of heavy wet snow at the trailhead to 20cm of moist powder near the ridgeline. Wind affect is pronounced, with shallow wind slabs and exposed rain crust comprising the majority of travel along the ridge, though softer deeper snow could be found just beyond the lee zone in sheltered trees. 

Kickturn tests could only produced isolated failures and small shooting cracks up to 2m (see photo). Hand pit tests failed easily on dry snow 20cm down, and where more snow was deposited was well-bonded to the rain crust. Ski cuts on un-corniced entrances to the Hose and Main Avy Path only produced very small shallow slab releases. Skied the Hose down and had no other signs of storm slab or loose snow problems.
