Location Name or Route: 
Electric Lake Bowl
Weather
Sky: 
Clear
Wind Direction: 
Southwest
Wind Speed: 
Light
Weather Comments: 
Nuclear NE/N winds have had their way with the Wasatch Plateau. Most open terrain (which is a majority of the area) has been wind jacked by N winds, even blowing up slope in usual protected areas, and ending the go anywhere and ski/ride anything, but wow, it was good while it lasted.

Snow Characteristics Comments: 

Don't get me wrong, there are still very protected areas lower down in trees that were loud powder, and we even got into what CG has referred to as Porn, rapidly warming E facing slopes were creamy and thick at mid morning, but by afternoon were already setting up with surface MF layer.   South facing rollers were everywhere as the sun warmed things up, so in summary, if you can think of any type snow condition it was out there today.  The challenge was reading where it changed, because it was not so apparent, and getting thrown into the back seat or over the bars was a roll of the dice. 

Red Flags
Red Flags: 
Rapid Warming
Avalanche Problem #1
Type: 
Wet Snow
Trend: 
Increasing Danger
Problem #1 Comments: 

Sun is higher in the sky and days are longer as we move into February, lower elevation down canyon was nearly all roller balled out as we came down early afternoon

Avalanche Problem #2
Type: 
Persistent Weak Layer
Trend: 
Decreasing Danger
Problem #2 Comments: 

We chose to poke around in sheltered N facing looking for persistent weak layers down in the pack.  Old surface hoar layer was still there where we looked, see video on ECT below, this is likely healing with time and warmer temps

Snow Profile
Aspect: 
Northeast
Elevation: 
9400
Slope Angle: 
30
Comments: 

Buried surface hoar still intact, down at 163 cm,  ECT 22 Q1, and healing

we did not dig much below the old frozen graupel layer at 118 cm, pack seems in good shape overall, just time for new snow.  Surface was highly variable with pockets of surface hoar, wind board, sastrugi, old worn cornices, and dampening snow from daytime heat.

FORECASTER COMMENTS:  This is the the only full propagation that I've seen in any tests over the last four days. I've traveled from Pleasant Creek down to 12 Mile Canyon and found this layer to be stubborn with no clean shears.
