Observation:   Took the opportunity for an overflight of the CNF Wilderness Study Area (WSA) boundary on a beautiful cloudless day. Route: Girdwood -> Whittier -> South to Nellie Juan Lake -> Return to Girdwood. The lack of snow across the zone is quite evident from the air. Crevasses are an obvious hazard in many glaciated areas south of Whittier where a year ago these areas had the look of a smoot >>>> see observation for complete description

Observation:   Skinned up Magnum yesterday (3/28) and there is evidence of cornice calving, exactly as predicted in the Avalanche Advisory. The chunks that have broken off left impressions of about 2 feet deep in the snow pack but didn't trigger any avalanches nor were there any other signs of instability. Snowpack has a frozen top layer on the South/East facing aspects at the lower elevations, up to about 2000- >>>> see observation for complete description
