We skinned up from the Manitoba hut on the normal uprack to 3070 ft. and dug a pit before skiing down from our pit location, slightly below the ridge top.

While we did not see any of these red flags at Manitoba, we did see results from natural activity in steeper terrain while driving back in the afternoon. See attached photo for an avalanche we saw at MP 53 on the East side of the Seward Highway.
A low hanging broken cloud layer with mostly clear skies above. Light breeze, and very light snow falling.
At the cabin, a hard, punchy crust existed on the top of the shallow snowpack. As we climbed, the snow pack got deeper and the crust grew thinner until slightly above tree line where the crust disappeared and the snow pack was the deepest we saw.
Hard ice layer near the ground with a layer of facets on top of it, caused a collapse during a CT, but we did not get the same results with an ECT. However, the ECT column may not have been properly isolated leading to these inconsistent results.
