Aspect: North East, East
Elevation: 9,000-11,000

Avalanches: Large remote triggered D1.5 on SE aspect on a steep convex roll. Other avalanches were observed up slate river N-E.
Weather: It was as clear as a bluebird day can get with temps in the low to mid 30*F Wind Calm to light on the ridgeline out of the west.
Snowpack: Touchy!! Signs of instabilities started to be noticeable at 10,500ft with large loud whumpfing and collapsing. The overnight cold temp produced small SH growth in the valley and protected areas up to 11,000ft. The new snow has started to stiffen to 4F with area of wind board ranging from 2-5” thick HS ranged for 300-250cm. Testing the snowpack to check the old snows interface for NSH resulted in CTM19Q1 30cm down on NSH East 10,000ft. Other instabilities were large checking on the downhill sides of multiple trees.
