ECTP6 down 40 on 1-2mm facets. At 1950m, 5cm of moist, pencil hard windslab/crust overlies 15cm of 4F decomposing fragments. This sits on 20cm of 4F-fist facets, loosening progressively as you approach the Mfcr. Facets appear to be rounding closer to the surface, but remain pronounced at the crust. Multiple 15-20ft shooting cracks observed in support 20 degree terrain on ski down.

Multiple sz 1-1.5 naturals off steep rocky features. View was obscured on run out of most prominent slide, but appeared up to sz2. Lookers right of the middle rock band below toe of the glacier. Likely from yesterday but couldn't confirm.
