Snowpack

Rain crust present to 2100' under 2-4' of snow.
Below 1500' the snow is still moist to wet below the crust.
Pit @ 2100', W aspect, 32 degrees. 1cm rain crust was 100 cm below surface. February 9th buried surface hoar 125 cm below the surface. HS: 368 cm (wind loaded area).
Eddies snowpack is definitely deeper than south on the pass. There is still the potential to trigger the surface hoar in a shallower part of the slab.
Did not do any stability tests below 1500' where the snow that is still moist below the rain crust. Curious to see if the surface hoar is reactive at all under this set-up. Lower likelihood of affecting that layer. Will take some further investigation.
Probed across the slope in this area and found HS varied from 230-380.
Hand pits on the way up showed the snow sticking to the rain crust.
None of the steeper rolls on Eddies W slopes were triggered by skiers today.
