Observation: Turnagain
Location: Tincan
Standard SW route to 2600′
Obvious signs of instability
Observer Comments
Some cracking under skis in isolated pockets of drifted snow
Weather
Clear and sunny
No precip
~20F
Winds light and variable
Snow surface
1000'-1500' - surface hoar 1-2cm near road level gradually getting smaller with elevation and very small or absent near 1500'
1600'-2000' - 1-2" of loose faceted snow in sheltered areas
2000'-2600' - Variable surfaces ranging from pockets of wind drifted snow to sastrugi to melt/freeze crust
Snowpack
1000-1500' - 3-4" of settled snow that is faceting out on the ground with surface hoar on top
1600' -2000' - 1" melt/freeze crust on the ground gradually getting thicker with elevation. Height of snow ranged from 3" to 6" near 2000'.
2000' - 2600' - Melt/freeze crust found on ground everywhere and averaged 3-5" thick and appeared to be well bonded to the ground. Heights of snow ranged from 3" - 18" and was highly variable from exposed m/f crust to sastrugi to isolated pockets 5" windslabs sitting on facets. See photo diagram as an example.
Snow pit at 2600' on a SSW aspect of Tincan.
Surface conditions were highly variable in the alpine. Note the shiny surface conditions, supportable m/f crust.
Sastrugi in the Alpine
Anti dog tracks on melt/freeze crust at 2200'
1800' - snow depths are very shallow 3-4" with a firm melt/freeze crust sitting on the ground
Poor coverage at 1000', but creeks are freezing!!!

Seattle Ridge, SE face is pretty bare
