Triggered Avalanches

Did you trigger any avalanches? 
Yes
Was it intentional? 
No
Avalanche Type:
Wet Loose
Size:
Size 1: Relatively harmless to people
Elevation:
4400 and below as of 10:30 am
Aspect:
SE
Comments:
Shortly after descending below the weather station (skier's right) we triggered our first of many D1 wet loose slides at 10:35 am. Virtually all avalanche slopes or convex rollovers below this elevation slid similarly.

Signs of Unstable Snow

None reported

Observations

We left the Marble Mountain lot around 2:45 and went up Worm Flows. Snow below ~5000 ft was slushy, but we were pleased to find that the upper elevations were quite firm (ski crampons would have been nice). We began our descent just before 10 and found excellent (but increasingly soft) skiing everywhere above ~6000 ft. Below the weather station (4440 feet @ ~ 10:30 am) nearly every avalanche slope or convexity produced small wet loose slides.

Advanced Observations

Observed Avalanche Problem #1:

Comments: 
S - E aspects below 4400 feet after 10:30 am. Very easy to trigger. Very small D1 on these slopes, but potential for larger slides on the higher & longer slopes later in the day.
