Snowpit Observations
More detailed information about the snowpack: 

Route: Up N face of Red Mountain by the usual skin track on the W side of the face. Back down the same way.

1000 at 7600', E aspect- Tair 5deg C. Foot pen: 25cm. Surface snow still dry.

1030 at 8000', E aspect- Hand shears failing with moderate to easy force, non-planar about 15-20cm down. Top of the snowpack: 0-10cm = F hard, moist, DF. 10-20cm = F hard, dry, DF. 20-23cm = I MFcr. 23-38cm = F hard, dry, 3-4mm facets. HS = 125cm. While tracking this crust/facet combo, it seemed like the crust was very hard and supportable in some areas and breakable in others.

1045 at 8200', E aspect- Investigating the CR/FC combo after a few easy hand shears in that layer. CTE SP x2 down 30 in the facet layer. ECTPV in the same layer. The crust/facet combo seems to peter out on N aspects and above 9500'.

1100-1200, 8500' to 10000', N aspect- wind affected snow became dominant. Multiple kick turn tests had touchy but localized cracking. (See photo) 4F to P hard wind slabs on E side of rollovers and 4F to 1F sastrugi or K wind crusts on W side of rollovers.

1200 at 10100, N aspect- Tair 4deg C. Foot pen: 20cm to 0cm depending on the hardness of the wind slab. Several D1 wet loose slides from today on the S aspects of McGee at middle elevations.

Driving home: Many roller balls and small point releases on E and S aspects that hadn't been there this morning.
