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.

Melt-freeze crust 80 cm down CT 16 RP, CT 21 RP above crust. ECTX on this layer. November 23rd buried surface hoar 115 cm down. Deep tap test 22 RP. Surface hoar is laid over.
