Supportable corn on solars with mank on low/mid northerlies. Warm wind buff up high.
Melting out soon. A bit of hopscotch up to Silver Lake Flat. The road had standing or running water over ice in the afternoon.

Problem #1 Comments
Looked at the structure at 7750' ENE and 8750' ENE.
Lower elevation showed stable snow with alternating crusts and 'mixed forms'. Facets do linger in between crusts as well. Snow is isothermal. Photo below.
At 8750' ENE, HS was 130 with a snowpack that looked similar to the one found in the Wilson Glades last week. Slab is 40cm thick with alternating thin crusts and rounds. A thin 5mm mf crust caps the drought layer PWL.
ECTP 29 and 35. 2.5mm facets were dry and loose. Although slightly rounding and bonding, it doesn't matter. Did I mention loose? Hazard still exists for human triggered avalanches on this layering.
I worry about this type of layering being suspect for wet slab potential with the weekend warm-up: slab over crust over dry facets. We'll see.

Problem #2 Comments
Saw zero new wet point release sluffs of any sort scanning east Box Elder to the 3 Temptations to everywhere between south Lone Peak to the AF Twins. Cool north breeze and gradual warm up allowing for stability.
