Red Flags
Red Flags: 
Poor Snowpack Structure
Red Flags Comments: 
No red flags observed today but I only made it to 7,000'. I assume that the snow pack is still weak up high on northerly aspects.
Avalanche Problem #1
Type: 
Normal Caution
Trend: 
Same
Problem #1 Comments: 

At the lower elevations normal caution is warranted.

Avalanche Problem #2
Type: 
Persistent Slab
Trend: 
Same
Problem #2 Comments: 

Based on what I saw in the snowpack before I left for over 2 weeks, I would assume that the facets on northerly aspects above 8,000' have not healed.  Lower elevation facets (<7,500' ?) are wet based on the snow profile below.

 

Of concern is that by this time of the year we are typically dealing with new snow related hazards, This year is different and warrants extreme caution.

Snow Profile
Aspect: 
North
Elevation: 
7000
Slope Angle: 
40
Comments: 

HS = 16", HST = 5".  7" of new snow siting on a stout crust.  This is the same crust (pencil +) that has allowed travel at the lower elevations in February.  The underlying facets are significantly wetter then they were last month (I have not been here since Feb. 25th)

There is a slight crust (above glove)  below todays new snow that formed on top of snow from the previous storm (March 14th?) (glove is pointing to this layer).

Photos below:

1. Wet rounded facets.

2.  ECTN results above crust.

3. High country obscured by clouds.

SW Utah Snotel storm totals:

Pahvants:

Pine Creek: 8"

Bob's Hollow: 3"

Tushers:

Big Flat: 6"

Kimberly Mine: 8"

Merchant Valley: 3"

Eagle Point Resort: 7"

Brian Head:

Webster Flat: 4"

Midway Valley: 4"

Brain Head Resort: 9"

Overall I would guess/assume a considerable hazard in the high country based on new snow and underlying facets.  I have been out of town and did not get into the high country today.
