1100’: 50cm soft snow, with patches of knife hard ice in places
1600’: 50cm soft snow over a thick melt freeze crust
2000-2200’: see pit #2 for general structure - probing generally revealed 50-60cm of soft snow over a crust and HS 120-160, with outliers of HS 40-200+ depending on wind affect at top of treeline.
2300’: see pit #1 for general structure
2400’: generally, 20-30cm soft snow over crust with variations from wind scoured areas with HS <20 to wind loaded areas with HS 200+

~2000’ on Eddies uptrack at 11:30, broken sky with calm winds at location but visible wind transport on Eddies summit.
Pit #1 structure in wind loaded location; this photo shows the top 145cm of snowpack.
PIT #2 - structure at 2000’. The second line down indicates where the buried surface hoar was found, and everything from mid handle down was pencil or knife hard.
