Snowpit Observations
More detailed information about the snowpack: 

Toured to Old Man's Bowl via Tobacco Flat. Snow coverage is minimal but enough to skin once a few hundred feet up the moraine in the gully. Coverage overall is quite thin, with 10-30cm of snow being the average until rounding the corner and getting into the bowl. Lots of evidence of wind stripping and deposition, with N aspects getting the majority of the loading. Widespread surface hoar up to 3mm was found on all slopes and all aspects observed.

Dug full profile pit to see what is happening outside of the Lakes Basin, profile attached.

General snowpack impressions are that there is a weak layer of faceted grains underneath a very stiff slab of wind deposited snow, and that while large column tests were not in agreement, additional load may not be tolerated well. All small column tests failed under easy or moderate load, CT1 SC being the most notable. PST 26/100 (End) showed propagation potential in this weak layer, though ECTN16 did not propagate (this is most likely due to P+ hard layer above not being fully isolated with cord)
