Comments
Over the last 3-4 days, the snowpack has settled 10-15cm, makes the upper 90cm much stronger and homogenous. Today's sunny, warm weather broke down much of the surface hoar, which was now quite rounded.
I dug a pit at 9,554 in the Canyon periphery.
110cm total depth
Due north at 32 degrees
Basal facets are still sharp and angular - not breaking down.
ECT test = 30/nil
Compression test = 30/nil
The upper 90cm snow structure looks very good - 4F for the top 60cm and 1F for the bottom 30cm, and then 20cm of basal facets.
The surface snow quality is still good on many aspects.
I think the majority of the central Wasatch Mountains are at low to moderate danger, but in the upper elevation, north facing areas with large collection zones (Pfiefferhorn, Y-Couloir, Birthday Chutes, etc.) there is still a high danger with serious consequences.
Today's Observed Danger Rating
