Avalanches: 5 harmless wet loose avalanches ran naturally on a SW aspect BTL. I could see a fresh D1.5 debris pile on a S aspect NTL, looked like it might have been a slab release but too far to see clearly.
Weather: Broken skies. Warm, greenhousing.
Snowpack: No signs of instability across various rollovers and steep roadcuts BTL. Mid-pack facet layers produced non-propagating results. The structure on southeast aspects appeared to be the most fragile for incoming loads. Northeast aspects could handle a larger load but will produce larger slides. See photos and captions
NE aspect BTL. Â ECTN 21, PC on 1.5 mm F facets. Â F to 4F+ slab.
N aspect NTL. Â ECTN 22, BRK. Â 45 cm down, on F+ 0.5 mm rounding near surface facets. Â F to 1F slab.
SSE aspect BTL. Â ECTN3, BRK. Â 45 cm down, below a thin meltfreeze crust on F facets. Â F to 4F slab.
