Snow Characteristics Comments: 

Storm snow from 28th/29th holding well from lack of wind and direct sun.  Still had to walk in the mud a mile or so from the Big Springs parking lot.  Some southeast to southwest slopes will be have a zipper crust in the morning.  Same for northerly slopes below roughly 8000' that were affected by greenhousing.  By 7500', small push-alanches in the 5" dampened storm snow would run on steep test-slopes on the underlying melt freeze crusts.  

Avalanche Problem #1
Type: 
New Snow
Problem #1 Comments: 

Only minor cracking noted on switchbacks 8" down in the storm snow.  CT18x2 in same layering noted as well though showed no propagation with ECTs in multiple tests.  Only reactive in one mid-slope rollover where the angle increased briefly to over 40 degrees.  New/old interface seemed to have a good bond; would imagine storm snow instabilities to be mostly settled out by tomorrow.  

Avalanche Problem #2
Type: 
Wet Snow
Problem #2 Comments: 

Plenty of cold dry snow ready to run with sun/heating.  

Comments: 

Moderate today; forecast tomorrow depends on overnight winds and chance of sun/heating tomorrow.
