Signs of Unstable Snow

None reported

Observations

There was no obvious avalanche activity on S facing slopes on the way up the Eightmile drainage and we saw no signs of instability during our ski. Conditions were extremely variable ranging from deep windblown pockets of unconsolidated snow all the way to scoured crust. Leeward rolls were deepest with 1-3 feet of transferred snow.

Looking at Axis and some of the larger N lines there was also no obvious slide activity.

Advanced Observations

Observed Avalanche Problem #1: 
Persistent Slab
Comments: 
We dug a hasty pit on a SE aspect of peak 7057 at about 6600 ft to get a quick read on the conditions. At approx 140cm the upper storm slabs ended at a crust with a clear layer of unconsolidated facets between 140 and 150 deep. We did not dig past this layer.

The upper snow levels were F/4F through 90cm and 1F below...the picture is not an accurate representation of the hardness. :|
