Route & General Observations

Standard approach post 12/13-14 wet storm and after new snow 12/15. No obvious sign of instability noticed on this aspect or surrounding slopes. Stout (frozen) rain crust to 2,200 with 2-3 inches of new snow on top and wet to moist snowpack underneath the rain crust. 6-8″ of new snow since 12/14 above 2,200 ft. Near surface rain crust becomes breakable 2,200–2,800 ft and disappears by 2,800 ft. Prominent older rain crust 60cm down at this elevation (3,200 ft), but seems well-bonded to layers above and below.
