Snow Characteristics
Snow Characteristics Comments

Slight wind skin in some exposed areas. No co/cr observed. No new avalanches observed. No slab results with several small cornice drops near TLP........ 2 pits: #1, WNW @9700'; HS 100cm; CT12, CT13, ECTN12 all within storm snow; CT27 SC, CT25 SC on facets down 60cm.. #2, NE @10,000'; HS 170cm; failures observed within storm snow; CT25 SC, ECTP25 SC, both at the ground. Also got 2 ECTP 30+ in the same pit; we were trying hard for weak snow in this one........ The slab is getting thicker, our PWLs are becoming harder to trigger. With a sunny weekend on its way, and powder-starved community I wouldn't be surprised to hear of some close calls over the next few days.
