Standard uptrack to ridge. Skinned over to Hippy Bowl and looked into Todds Bowl.

Red Flags
Red flags are simple visual clues that are a sign of potential avalanche danger. Please record any sign of red flags below.
Observer Comments

None observed. Overall signs pointing towards storm snow stabilizing and the concerns about persistent layers decreasing.
There was some evidence of small slides in Todds and the chutes into Todds from this storm. We also got a better look at the larger debris pile in Todds from the Thanksgiving weekend storm.
Hippy bowl had old debris and a blown in crown that may have been from this storm. Some of the debris is from the earthquake slide in Hippy Bowl.
