Signs of Unstable Snow

Observations

Snow on trees at 3800’. The trees on the upper slopes of arrowhead did not have snow however. We realized why when the sun poked out for 10 min. The solar exposure was strong and we observed natural pinwheels below our skin track, and on the upper slopes of arrowhead. We bailed on the summit at this point.

Dug a pit for fun at 4,500’ on a north aspect. Found a 3cm crust down 28cm and a more sig crust down 75cm. EctN 20 down 23cm and ct14 rp down 23. No surface hoar or nsf observed at this interface. Moist snow all the way down.
