Skied one of the South facing slide paths down to the Duffey Lake Rd off the West Shoulder of Mt Rohr today, with. The skiing was better than expected, with some great turns in facets on a NW aspect on the way up between 5800' and 6200'. Below this elevation a thin crust (Nov. 29th?) became grabby on the skis, and above this was a wind-crust on the surface. The South facing slidepath produced some good facet turns from 7300' down to around 6300' where the snow became breakable.
Avalanche activity:
3 size 1-2 natural slab avalanches observed on a South West aspect around 6000' in convex rocky areas, suspect a couple of days old. 1 old size 2.5 avalanche crown observed on East aspect on most southerly glacier on Cayoosh Mountain in steep start zone.
Weather:
-19 at the salt shed at 9:10am
-17 on the West Ridge with light winds from the NW at 1:15pm (not as cold as expected)
Snow Profile:
11:30am
5800'
North West aspect

Height of Snow 240cm
30 cm's of facets (fist hardness) over 1 cm thick crust (Nov. 25th), with a thin (less than 1cm) rotting crust down 10cm (Nov. 29th?)
Hard shear (resistant) down 31cm on 3mm facets below the Nov. 25th crust.
