Observations

Bailed on Mazama bowl approach as rollerballs were active and top 4+" were wet. Changed to 1/2 lap of upper Iceberg trees and back to Bagley. Skied a last lap on Martha's which was better skiing. Zipper temp crust on all aspects in Bagley, but soft and mostly rippable in the shade.

There was a widespread storm slab cycle last night or early this morning on multiple aspects of Table and Herman

Observed Avalanche Problem #1: 
Wet Loose
Comments: 
Widespread wet loose to small D2, some piles deep enough to bury on Herman (little Swiss ran during day). Early afternoon winds and cooler feel seemed to limit shedding
