Signs of Unstable Snow

Observations

Toured up to the Snow Lake divide, found a thin breakable crust all the way up with thicker crust on southern aspects.
No visible signs of instability but tests revealed a highly reactive layer.
Quick hand pit on the apron above source broke clean when cutting the back.
We then did 2 compression tests and one ECT on the divide. These revealed a highly reactive layer 46cm down.
