Quick report

I found weak snow in most locations except on shallow, moist, sunny aspects. The slabs I found above the weak layers were either too thin or too weak to propagate a fracture. I observed limited wind-loaded areas where this would likely be a different story. 

I rode and walked on a limited amount of older drifts around the summit; this was the only location where I found boot-supportable slabs.

Mostly clear. Some thin high clouds midday that thickened in the afternoon, particularly over the Soldiers and W Smokys. Mostly calm, occasional very light wind. Temps were warm enough to cause steeper sunny slopes to become moist. These will develop another crust.

Snowpack

Snow amounts increase significantly at similar elevations from the Warm Spring winter closure to Dollarhide Summit. This is not uncommon, but more frequent early-season snows seem to have withstood melting and warm days near Dollarhide, creating a much more dramatic difference than normal. Start zones above Frenchman's Bend (8,000-8,500') were heavily disrupted by timber and held similar-looking coverage to 7,000' slopes near Placer. Higher snow totals and better coverage looks to extend over the summit into the Soldiers. 

NE @ 8,500', HS = 60 cm, burn area near Wx Station
See photo. Small surface hoar at the surface. A 45 cm slab grades from (F) near-surface facets to (1F) packed small facets. Very weak 20 cm thick layer of 3-4 mm depth hoar at the ground. A faint, fragile (12/6?) crust was noticeable down 27 cm. (11/30) produced ECTNs 13,14,15, and CPST 30/100 END. 

W @ 8,600', HS = 45 cm, previously wind affected
See photo. (11/30) was likely disrupted by wind here ECTX (x2). Facets under the (11/22) crust down 13 cm look problematic when we build a slab.

SE @ 8,800', HS = 40 cm, open planar
See photo. The structure here was not great, particularly below the (11/22) crust down 13 cm. I did not find weak snow at the ground. ECTNs and ECTXs below each of the two prominent crusts. 

SSW @ 8,500', HS = 20-30 cm, steep, open, planar
Steep SW, S, and SE have moist snow with a mixed bag of stout crusts. Slopes closer to Placer and Warm Springs are bare at this elevation. 

Avalanche

No new or recent avalanches were observed.
