WEATHER OBSERVATIONS
 HN24: 0 HST: 0 Sky: OVC Precip: Temps:
 Ridgeline Wind: Light from the W
 Blowing Snow: None Snow Available for Transport: None
 Comments: Some patches of blue sky at the head of Baker Ck in afternoon, but generally overcast.
AVALANCHE OBSERVATIONS
None Reported
SNOWPACK OBSERVATIONS
 HS: 100-130cm above 9500' 
 Upper Pack: Did not cover all solar aspects but generally found firm surface crust on anything with a bit of south aspect. Shaded areas had a few cm's of FC near the surface but didn't find extensive surface faceting. Lots of surfaces blown away to older crusts/hammered snow.  
 Middle Pack: FC near 12/19 were fist hard and 8-10cm thick capped by 30-40cm of 4F +/-. Where slab was weaker above FC (SE slope) saw propogation on ECT, but with a slightly stronger slab above FC (E aspect), got ECTN's.  
 Lower Pack: Only dug above 9600' and found generally strong snow below older crusts.

BOTTOM LINE
 Comments: Even with test results, still traveled with a persistent slab mindset and will continue to. I think most slabs in this area are just not thick/strong enough to see many big avalanches but I feel you could easily get caught of guard in areas with a bit of wind affected snow. Surface crust on solars may dampen new loads affecting 12/19 in this area.
