<p>Midpack has become quite weak and would not support the weight of a person on foot in many locations on N-E aspects below 8800ft. Foot penetration 60-80cm. Inconsistent, but positive results for propagation with snowpack tests. Layer of concern was 3mm depth hoar grains 10cm up from ground; On N aspect at 8800ft; PST 60/100 (END) x3 in 3 different pits with an average HS of 110cm, but one PST 20/100 (END) in an area where the HS was slightly shallower (85cm). All these within a 50m zone. ECTP 26 here, ECTX from the deeper profiles. </p>

Snowpack

Substantial greenhousing was occurring and turned the snow surface damp even on N aspects up to our high point, 8800ft. This is good for future stability given that we are now getting light snowfall to bury this layer, but is still likely to become a persistent weak layer at 8500ft and above.

Pushalanches seemed like they would be easy to initiate on steep slopes at elevations below 8000ft on off aspects.
