An inch of snow last night and no new snow accumulations today. No signs of instability. 

Strong easterly valley winds but calm winds up high. Light snowfall began around 4 pm.

Good views of several peaks in the park; no deep slab crowns. We saw debris from D1.5 storm snow avalanche from earlier in the week and a D3 wet avalanche from the Feb 8 rain event.
