<p>Was finding 10-15 cms of faceted snow and depth hoar near the ground on northerly aspects. This snow was damp and undergoing rounding, but still reactive to stability tests (further described.)</p>

Overall was not finding the new snow sensitive and could only produce moderate to hard shears at the storm snow interface (now buried about 25 cms - 10"). Some wind loading on lee aspects from SW-NW winds yesterday and overnight, yet wind slabs were shallow and not sensitive at all to ski cuts. Full propagation on ECT with the slab popping out at Q1/SC shows faceted snow near the ground remains a player. Grains appear to be rounding, but you can still clearly see the angular edges. Grain sizes about 1 mm. Photo/profile shows no temperature gradient, so this will continue to heal, but it appears to be taking its time.

Not entirely sure what to make of this as stability tests show buried persistent weak layer, yet haven't heard of recent activity on this layer.

<p>Full propagation extended column failing on facets/depth hoar near the ground. ECTP22 @ Q1.</p>

Super-dense and graupel-laden. Fun for traveling and riding and just the kind of snow we need in the early season. Some wind affected snow along ridges from SW-NW winds from Sunday into Monday morning.
