Some Duffy area observations from Lee Lau:

More for you.  Heal up soon Wango

From valley E of Cayoosh Pass. Pronounced change with a marked temperature inversion. -19 at valley bottom (1200m). - 5 at 2020, 0 at 2200m at ridgeline. Clear skies. Winds light from N explaining why there was windslab above treeline on NW ascent slope and also on NE slopes. 

Probed snowdepth 90 cms at 1600m, 135cms at 2020, 145 at 2150 all on NW slopes. 

Hasty at 2200m at ridgeline on SW slope; HS 90cms. Top 25cms fist, 35cms 4F, 30cms decomposing facets. Easy shear on windtransported top 10cms. Nil result on the 35cms and 55cms layers. Ski quality on the SW slope was very high but the inversion is supposed to persist tomorrow which should degrade quality.




    Thin thick layer of cloud passed over the area around 11:30. Flat light in the glacier!!
