From skier obs 2/27/21: "~6-8" of fresh snow. No wind loading or significant signs of instability. Calm winds with scattered clouds and occasional very light snow. Dug a pit at the summit. ... I found plenty depth hoar at the bottom of the snowpack. It was not as weak as what I've seen earlier this season (4F), but we're still talking 4+ mm grains with well formed cups. ECTX and PST 60/120 to end on the depth hoar layer. Pit profile attached."
