Observer Comments
Weather
Partly cloudy in the morning becoming mostly cloudy in the afternoon
Temps mid 30s to mid 40Fs
SE winds 0-15mph with gusts in mid 20Fs
Wind building later in the day
Wind blowing light flurries in the afternoon along ridge top
Snow surface
Supportable MF crust on all aspects and elevations to ~3000'. Was soft and corn like on solar aspects for the entire tour.
At 2300' there was 1cm recent new snow from earlier in the week and was dry on shaded aspects. On solar aspect this snow had transition to MF crust. Moist corn snow was consistent along ridge to 3000' on E to SE facing terrain.
Above 3000' the surface snow was more variable with a firm breakable 2-3cm MF crust and patches of 2-3cm wind deposited snow.
At 3800' on North aspect the top 10cm was dry snow that had also been wind deposited.
Snowpack
Probed in a few locations
~1800' HS ranged from 60-90cm
~2300' HS = 130cm
~3800' HS ranged from 70-200cm
At 2300' the top 20cm was MF crust with moist melt forms below. Snow surface was supportable to boot.
Dug one pit on a NE aspect at 3805' just beyond the corniced ridge on a wind loaded location, HS=195cm, Pit height was ~90cm. The top 10cm was new snow from earlier this week, sitting on near surface facets. NSF were .5-1mm in size and failed with hard force in a shovel tilt test. A 1cm MF crust was found 30cm below the surface and was hard to sheer in shovel sheer test. Compression test had no failure. The snow was pencil hard below MF crust. Could feel with probe weaker snow near the ground in the bottom 35cm of pack.
At ~1300' there are patches of no snow to 25cm MF crust
Corniced ridge above Ragged Bowl with an older crown mid-slope and old wet cornice chunks and rollar balls
Older avalanche, likely from March storm with debris and very faint old crown still visible. This was on East aspect.
1cm of newish snow from earlier this week on MF crust at 2300'
MF crust below 1cm of snow at 2300'
View of South - Southwest aspects of Goat peak and Goat Shoulder. Much of this snow shed during the March storm.
Poor visibility and winds picked up later in the afternoon
